Colorful Flowering Plants for Portland Landscape Designs: Geum (aka Avens)

Brighten Your Portland Landscape with Colorful Orange Flowers – Geum (Avens)

If you’re looking to add lively colors to your garden, let me introduce you to Geum, also known as Avens. This charming perennial bursts with vibrant blooms ranging from soft yellows, pumpkin and peaches to fiery oranges and scarlets, making it a sought-after choice among my Portland landscape design clients this year.

The Appeal of Geum in Landscape Design

I love incorporating Geum into my designs because it’s as easy to grow as it is pleasing to the eye. There are plenty of cultivated varieties to choose from, with color palettes spanning from subtle peaches to bright scarlet. Available in both low, path-edging sizes and taller 24-inch varieties, Geum is popular right now, especially with the recent introduction of hot orange and melon-hued cultivars that thrive in full sun.  This plant is also a great addition to pollinator friendly planting plans.

Some of my favorites include the sterile variety ‘Totally Tangerine’ and the sun-scorch resistant ‘Starkers Magnificum.‘ Other notable mentions are ‘Lemoncello,’ ‘Firestorm,’ ‘Mai Tai,’ and ‘Sangria.’ Each offers a unique splash of color to your garden.

Choosing Companion Plants

Pairing Geum with the right companions can make or break its beauty in your garden. Lavender makes an excellent partner due to its contrasting leaf color and shape. Avoid planting Geum next to Black Eyed Susan,  as their foliage can look too similar.  Tip: Consider using ornamental grasses to visually separate them.

Care and Maintenance Tips for Geum

While Geum is relatively low maintenance, informed care can go a long way in keeping it thriving. Plan for regular irrigation, especially if the plant is in full sun. Yearly garden mulching is beneficial, while fertilizer is not typically required. Deadheading is essential to prolong the blooming period and keep your Geum looking its best. If you don’t deadhead the plant will still look great but not as colorful for as long.

Geum in North Portland Garden

As for dividing your Geum, the new sterile varieties don’t typically require it. However, if you notice reduced flowering, woody stems, or overly clumped plants, it’s time to divide and conquer! This can also be a great way to propagate more plants for your garden.

Keeping Those Blooms Coming

Interested in extended flowering? Go for sterile varieties, as they channel more energy into blooming rather than seed production. In terms of growing conditions, differentiate between sun-loving Geums and those that prefer partial shade or dappled light.

Regular deadheading is a must for maintaining long flower production. Remove the spent flower heads just above the next bud on the stem. If your plant looks a bit tired, and you don’t want to deadhead each small flower, presto!  Cutting it back to the ground – ideally around mid-June in Portland – can rejuvenate its appearance for the season, though it typically won’t bloom again that year.

Watch and Learn

I recommend checking out a video from 2023 that demonstrates deadheading techniques. Toward the end, you’ll also learn about Geum varieties suited for woodland or shaded areas versus those thriving in sunny spots.

Privacy Screening Landscape Design for Kerns Neighborhood Portland: Part 2

Portland Plant Tips In Kern Neighborhood Residential Landscape Design

Plant tips for Kern Neighborhood residential landscape design.

In Part 1, I dropped by my clients Chris and Veronica’s Kern neighborhood back yard to get my eyes on their privacy tree, a Japanese elm called City Sprite planted 3 years ago by Landscape Design in a Day. It was doing beautifully but my clients had concerns that a talk with Honl Tree Care addressed. My visit also included some tips for the rest of the plants in their landscape design.

Kern neighborhood residential landscape design update.

Plant Health Care Tips

While I was there, I enjoyed seeing how much all the plants were filling in and checked on a few plants Veronica wanted advice about:

  1. Weed Prevention – To control the seeding on our native Heuchera and Fringecup perennials, cut back the flowering stalk before it goes to seed.  These two perennials provide food for bumble bees and many other important pollinators.  Also be sure to do this with the non-native Lady’s Mantle.  I like to pick the flowers of Ladys Mantle ( Alchemilla mollis) so yes please leave the flower on for the bees but be sure to deadhead it before it goes to seed and spreads.
  2. Re think and edit the plantings under the elm. A few plants are not getting enough sun now that our tree has gotten so much bigger.  The culinary purple sage needs a sunnier spot and could even go in a big pot and be moved.  I don’t see a good spot in the other planting beds for it so I would go for the pot approach.
  3. Shade plant tips for Kern neighborhood landscape design.

    Hardy Fuchsia thrives under privacy tree.

    The summer flowering Daphne and the hardy fuchsia near the purple sage look fantastic and can stay. The mass of Crocosmia we kept from the old garden is getting so big it is a little out of proportion.  You can always thin the Crocosmia.  Split the plant mass and remove the stalks in the middle as they are the oldest ones. Or maybe you are enjoying that very low maintenance plant as a large mass.

  4. Here is something to deal with soon.  The root weevil population is increasing. See my blog for no chemical advice on lowering their numbers.  They sure spoil the look of many part shade plants.

    Hosta Halcyon is slug resistant but root weevil re notching leaves spoiling the plants appearance.

  5. Your fun stepable groundcover that softens the edges of the big architectural slabs, Cushion Bolax, can be trimmed once a year or more to prevent it from growing over and minimizing our large pavers. Why trim it off the pavers?   Because the large pavers shape adds an attractive architectural element to the landscape overall and if it gets covered with the groundcover, we lose the impact.   See initial blog post from 2021 with testimonial from clients Chris and Veronica.

Before Privacy Tree

We placed the City Sprite Elm to provide privacy for the dining area and it’s doing a great job for us.  However, it has not been without some worry for my clients.

Beetle Damage on Privacy Screen Tree

Japanese elm is resistant to Dutch Elm Disease so we can use this tree as a long-term solution without worrying it might succumb to the disease that has caused City of Portland to remove so many mature and ginormous elm trees.  Veronica noticed a beetle eating the leaves and making lots of holes in the leaves in June.  She contacted me to enquire about whether this was a serious problem and if so, should she replace the elm?

Beetle damage to leaves of Japanese Elm, privacy tree chosen in Kern Neighborhood landscape design

Japanese Elm leaves with beetle damage.

As I am not an arborist, I make sure I know some great ones.  I talked to Honl Tree Care and sent them photos.  They agreed that the defoliation shown in the photo was not serious, were somewhat surprised that the elm beetle was feeding on the Japanese elm as this is not typical.  They are confident that her elm tree will not get Dutch elm disease.

The best course of action was to take good care of her tree with proper watering and put up with the beetle’s minor damage.  Mind you it doesn’t feel like minor damage especially in June when the beetle is munching away but by July the beetles are done and the tree is looking vigorous and downright robust in spite of the holes in the leaves.

Northeast Portland Test Garden for Drought Tolerant & Pollinator Friendly Plants

Tips for Tricky Native Plants in NE Portland Garden Design

Hilary Hutler North Portland Landscape Designer with Fox Tail Lilly  (Eremurus) an excellent pollinator plant

Welcome to part 2 of my blog series on drought tolerant pollinator friendly plants for North Portland home landscapes.

My disclaimer: This is my experimental and play garden so while some of the plants listed here are easy to grow and meant for a typical homeowner , others are a bit tricky or cause skin irritation, are a bit toxic or are especially thorny.  They are very interesting and plant-nerd cool plants that are also pollinator friendly and drought tolerant. I love foliage but obviously flowers feed bees and who doesn’t love flowers?

Mixing PNW Natives with Mediterranean Plants

Northeast Portland drought tolerant Canary Clover

Dorycnium hirsutum or Canary Clover is drought tolerant in St Johns Front Yard Portland Oregon

First up is Dorycnium hirsutum*. This plant loves it dry and handles the heat beautifully. It has such a soft sea foam green foliage that the wonderful flowers and colorful small fruit capsules (captivating on their own merits) are just the dessert to my mind. Be aware that this plant can seed around a bit. If you are not the person who can pull out a plant that has seeded in the wrong place…walk on by. The web still says it’s evergreen but here in Portland it often dies back and +comes back strong once the heat of summer hits. Common name is Hairy Clover Canary or Canary Clover, but it does not look anything like typical clover…hmmm. It lasts for perhaps as long as ten years but will cast a few seeds so you have a new plant to take its place.

Drought tolerant pairing of Lewisia & Artemesia Northeast Portland plants.

Lewisia thrives in north portland front yard also called Cliff Maid or Siskiyou Lewisia. Background silver plant is Artemesia ‘Valerie Finnis’.

I’m surprised with how big and healthy my Lewisia (our southern Oregon native plant Lewisia cotyledon.) I didn’t expect it to do well because it is planted in compacted heavy soil, (it prefers loose open dry soils) but it has really taken off.  It’s twice the size I typically see in Portland gardens.  As you can see by the picture,  I’ve planted it in front of the Artemisia ‘Valerie Finnis’.

Some Aggressive Plants Can Be Tamed by Planting in My Worst Soil Area

‘Valerie Finnis’ Artemisia is a beautiful mounding silver green shrub. It can be an aggressive plant so use it’s tendencies to your favor by planting it in a heavier clay soil area, as it can take over in loose open soil.  In my garden it is planted in my worst soil and totally handles the heat and dry conditions once established. You can let the flowers come on for a few weeks and then cut the whole plant back. The flowers are a pale yellow, that will feed pollinators and are not unattractive. I prefer to cut my plant back in May to prevent flowers because I love the silvery green leaves but also to keep the plant full.  If you don’t cut it back it gets leggy.   Note this plant dies back to bare stems in the winter.

Pruning tip for Artemisia:  I employ The Chelsea Chop, a pruning technique which is usually done in May and involves removing 2/3rds of a summer or fall flowering perennial.  This term was coined by Tracy DiSabiato in her excellent book “The Well Tended Perennial Garden” I happen to have sitting right next to my computer.  It’s an older book so you can get a good deal on this book at our Powells Books in Portland.

Drought tolerant & pollinator friendly plants for northeast Portland.

Drought tolerant planting combination is a thriller, colorful and great for pollinators too.

Create a Drought Tolerant Planting Combination for Year Round Interest

I’ve also had success with a combination planting of Echium*, Phormium, a small blue leafed Agave and Sedum rupestre ‘Angeliana’. This plant quartet has something going on all year round. The Phormium gives us year round structure, while the Agave gives both foliage color, contrast and texture. The mass of low semi-evergreen Sedum rupestre ‘Angelina’ adds a soft textured low foliage element and the Echium is the total drama queen with a 30” flower spike. Although Echium is somewhat toxic to people, the bees love it! And be aware the Sedum ‘Angelina’ is no angel and will spread, so best to use it in heavy soils and rarely water it to keep it polite.  Summer flowering Echium  must be pruned down at the end of the season to keep it from seeding about too much.  It can cause skin irritation so wear heavy gloves when handling this plant.  Echium will seed so I typically cut the spent flower stalk and put it in the garbage rather than my compost.

More Summer Flowers for Bees in North Portland

California Fuchsia, drought tolerant plant for Northeast Portland gardens.

Flowering for four months straight in hot full sun with no irrigation is my idea of a drought tolerant plant for my north Portland garden.

Epilobium ‘Catalina’ – California Fuchsia loves the hot dry Mediterranean summers we have and flowers from August through November. I see the hummingbirds flock to this plant for months.  Once it was well established it has never been watered since. This plant gets trimmed back a few times a year to keep it looking great but it’s worth it.

It also looks great adjacent to this public sidewalk in northeast Portland planted in this boulder wall.

Pollinator, bee friendly northeast Portland Eryngium.

Eryngium ‘Big Blue’ pulls our native bumble bees in by the droves. Like the Sedum ‘Matrona’ the flower itself is made  of many tiny flowers so lots of food for pollinators in a single flower.

Here’s a perfect plant that is both pollinator friendly and drought tolerant.  Eryngium ‘Big Blue’ –  Sea Holly in addition to attracting and feeding lots of pollinators, it adds dramatic beauty through the summer landscape and well into fall. The seed heads dry and remain a part of the garden view long after the silvery blue flowers have faded. Unlike many plants that claim to have blue flowers only to disappoint, this flower is absolutely blue.  And don’t forget our native bumble bees-they adore feeding from my Eryngium Sea Holly.

Purple Flowers Pollinator Plant Combination

Monardia Bradburiana – Eastern Beebalm is best in heavy soil and some shade to slow it down.  It is an excellent pollinator food plant and is native to the Midwest.  It is planted with a poppy called ‘Lauren’s Grape’ and the deep purple of this poppy is simply amazing.

Honey bees are busy feeding and collecting pollen from this dark purple poppy flower.

You can grow it from seed and here is a source, Renees Garden   For great contrast with the poppy flower and foliage, I used Sedum ‘Matrona’ for its large succulent leaf.  The big flat umbel flower head is made up of a host of tiny flowers and has hundreds of nectar sites for pollinators.  It’s mauve purple foliage is a dazzler with this planting combo.

My landscape in north Portland is a perfect place to experiment with plants for a drought tolerant and pollinator friendly garden in the Pacific Northwest.  With a thoughtful selection of plants, I’ve created beautiful and relatively low maintenance plantings that provide for pollinators, and is very drought tolerant.

Drought Tolerant Plants for Front Yard Curb Appeal In Portland

Evergreen Ground Cover Plantings for Portland Front Yards

This blog could be called many things…..Drought tolerant Plants for Front Yard Curb appeal in Portland or  Evergreen Groundcovers for Front Yard Curb Appeal but actually it should simply say these plants together are my favorite all season interest groundcover.

Low Water Ground Cover Plants – Heathers with Succulents

I want to introduce a drought tolerant heather that looks fantastic with hens and chicks and talk about how to use these plants for year round good looks in your Portland landscape.

Reasons to use Heather with Succulents or Hens and Chicks

We garden designers want attractive planting combinations to be year round colorful attractive plants that look great together, suppress weeds, feed bees and are simple to care for.  This is my 2nd blog of three showcasing the use of low water and drought tolerant plants.

What is Great About Planting Heathers and Hens and Chicks together?

Drought tolerant heather, sedum and hen and chicks landscape in Portland.

Shortie Heather  (with Sedums and Red foliaged Hens and Chicks), grow nicely in rock crevices

Contrast!  The fine soft needles of the heather, the large blunt shape of the Sempervivum leaf and the rosette that it forms creates a strong contrast.  Using these combinations really tickles my designer’s fancy.  Using contrast is an important tool for design.

Drought Tolerance:   They both need well drained soil and must be irrigated the first summer to establish mature drought tolerant roots.  So yes plant them together – they are a perfect fit.

Heathers and hens and chicks are evergreen, provide multiple foliage and flower colors to create interest.  It’s fun to see a gold leafed heather with the dark red rosettes of a hen and chick by the front door in winter.  No wonder I love to use them for a colorful year round landscape planting plan.

The Shortie Heathers are My Favorites

Texture galore with drought tolerant evergreen groundcovers including heather, hens and chicks and sedums

Heather and succulents make a tapestry of color in the garden of Marcia Peck on ANLD garden tour.

The shorties – Besides being so attractive these very low (4” tall or less) heather (Calluna vulgaris) are well worth it because they need very little to no pruning at all.  Some clients don’t remember to prune anything so these shorties are just right for them.  All the other types of heather have to be pruned.  I’ve nicknamed these heather ‘shorties’ to set them apart from the many many other kinds of heathers.  If you call them a “shortie heather” at a plant nursery they will not know what you are talking about.  Stick with the latin and look for these at specialty growers and nurseries.  See end of blog for where to buy these special heathers.

I like to use a very short heather with my hens and chicks like this three inch high heather called Calluna vulgaris ‘Mrs. Ronald  Gray’. This heather has needles that grow in a configuration that look like tiny ferns fronds and is my favorite of them all.   Other very short 2 inch to four-inch-tall heathers include Calluna vulgaris ‘Caleb Threkheld’, and ‘White Lawn’.  I use these shortie heathers in a variety of situations with many different kinds of plants but they look especially good with the succulents. They will also drape over a wall nicely.

The Difference Between Drought Tolerant Heather and Other Heathers

The stems look like feathery tiny ferns on this unique Calluna vulgaris, Mrs Ron Green (shortie heather)

I want to be sure my readers will understand that not all heathers are drought tolerant (and most of them are not shorties either).  Heathers named Calluna vulgaris – Scotch Heather (summer and fall flowering heathers) are very different from the spring flowering heathers (Erica carnea and Erica darleyensis) in terms of their soil conditions and water needs.  The Calluna must have well drained soil. They must be watered regularly and carefully their first summer, after that, they prefer less water and can become drought tolerant after just a few years of maturity.   They need full sun or at least 8 hours where Erica carnea can make do with less.  Erica darleyensis can take light shade although I like to grow them in full morning sun.

I Water My ‘White Lawn’ Heather Once a Month in Summer

My Calluna vulgaris ‘White Lawn’ at my vacation house gets watered once a month if its been hotter than usual in the summer.  I’m only there once a month and they even made it through the heat dome of 2021.

Plant Heathers in fall

Life will be easier, and kinder if you plant your heathers in the fall-best practice.  Planting in early spring would be next best.  Planting in late spring or early summer will mean complete devotion to watering these plants.  It’s easy to kill heather their first summer and here is why – most plants leaves will droop a little and let you know they are dry.  You water them and all is forgiven.

Heathers Cannot Dry Out The First Summer

Not so with heathers – Heather cannot dry out the first summer, not even once or it’s all over.  This is why planting in the fall is easier on you.  If the chance they will have to be replaced come fall is not a problem for you, you have nothing to lose except the plants.  Most of us won’t be planting 50 of these so our loss is minimal except for the shorties which are harder to get in the first place…..still calculate your potential loss and decide if you want to gamble now that you have the facts.

No Pruning for the Shortie Varieties of Calluna Vulgaris – Scotch Heather

Portland landscape with freshly pruned heather.

Calluna vulgaris – heather freshly pruned at the Oregon Garden. These heathers get about 12″ tall and must be pruned each year.

Taller type heather must be pruned thoughtfully every year but mostly one never needs to prune these shortie Calluna vulgaris – Scotch Heather.  I have plants Calluna vulgaris ‘White Lawn’ that are over 10 years old.  I’ve let one heather spread out and moved any hens and chicks that got in the way.  I have a patch that is over 15 years old and it’s about 24″ wide now.  I like it that wide and I still have room for plenty of hens and chicks.

Drought tolerant Calluna Vulgaris heather in Portland landscape.

My large two foot swath of Calluna vulgaris ‘White Lawn’ gets little to no water at my vacation home. This is what I call a “shortie” heather.

If you are still with your heathers in ten years, you can choose to either referee so the heather doesn’t totally bury the hens and chicks as it matures by carefully pruning out a section of the heather or….You could be a lazy gardener and just let the heathers grow over the top of the hens and chicks since by then you will have lots and lots of the hens and chicks.  I love the combo so I have done a little of both. Just realize that the section you cut out of the heather will not grow back.

Happily hens and chicks are so easy to transplant.  Sometimes I pick little chicks off the mother plant and tuck them into a cooler spot in the ground even with no roots on them at all and often they root and thrive – they are that easy to transplant. Learn more about hens and chicks.

Finding the Shortie Heathers to Buy

So perhaps I’ve convinced you that these shorties heathers are just right for adding full season color and interest to your low water landscape.  Where to buy them?

Highland Heathers – Janice Linewebber can u.p.s. right to your door. If her web site is not updated just e mail her at hheathers@canby.com  Ask her if she has any Calluna vulgaris that grows only 3 or 4 inches tall.  She will probably ask if you are my client…I love these little shortie Calluna vulgaris heathers so much in my designs.

Heaths and Heathers is mail order and while there are threats of retirement….so far we can still order from her. She is also on Facebook as Heaths and Heathers Nursery and is in Washington.  Ask her for substitutions as she has some shortie heathers I’ve never grown or used. A shortie is 4″ or under when mature.

There is a large wholesale grower in the area called Little Prince that sometimes grows these heathers. Therefore, I have found them at Cornell Farms and Portland Nursery at times.
