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.

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

Seed heads can be snipped off to prolong the color show of Geum in Portland garden

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.

Low Maintenance Ornamental Grasses for Your Portland Garden: Part 3 of 3

Switch Grass is a Native, Low Maintenance Addition to Your Portland Garden Design

Switch Grass: Colorful grass blades with drought tolerance too

Switch grass is a native American grass that offers dramatic color and form, making it a standout in any garden:

  • Mass Planting: This grass looks fantastic when massed or used as a focal point. It’s particularly effective in modern landscapes but fits well into naturalistic gardens too.
  • Seasonal Interest: With its vibrant mid-summer and fall colors, switch grass provides interest when many other plants are fading. I have noticed many of the newer varieties of switch grass blades color up even by mid June depending on how hot it has been.
  • Water Needs: Once established, switch grass is very low water. However, it’s crucial to plant it in well-drained soil. Avoid areas where water can puddle, as this will cause the roots to rot. If you still have powerful overhead sprinkler spray be aware the water spray can cause these grasses to fall over.  Drip irrigation is better for this reason and that it is easier to water deeply and infrequently which is a perfect fit for this grass.
  • Height Considerations:
  • Stick with grasses under 4′ tall for low maintenance.  I always use shorter cultivars 36 to 44 inches tall to avoid my clients having to add supports.  But, taller varieties (such as 6 or 7′ tall switch grass) can be so stunning if you’re willing to put a ring or other support around the plant in spring.  Piet Ouldalf, a famous garden designer uses heavy metal rings with feet (the ring was about 14” to 18”) around his 6′ tall ornamental grasses.  I found this video link on the web for a grass ring but wow these grasses in the video are huge and much wider than any of the tall grasses that I use.   I was in Piet’s garden back in 2001 and saw the supports he uses.  It made me laugh because I had thought when my tall grasses flopped that I was overwatering or doing something wrong but even the master uses supports for tall grasses.  If you are an adventurous gardener, willing to use supports, go for some of the tall varieties like 8′ foot tall Thundercloud Switch Grass.

Switch grass is a versatile and resilient choice, offering beauty and adaptability to various garden styles.  It doesn’t provide well for Willamette Valley native insects but it pairs beautifully with pollinator friendly plants like Blanket Flower, Salvias, Penstemons and more. It makes an orderly but loose effect with native pollinator friendly shrubs like Coyote Bush.

Creating a custom landscape design requires a deep understanding of plant behavior. As a landscape designer, my goal is to select plants that not only look beautiful but also thrive in your specific environment with minimal maintenance. Here’s how I can help:

  • Custom Designs: I tailor designs to fit your space and lifestyle and your eco consciousness.  I won’t proselytize but am happy to create plantings that feed our native insects.  Birds gotta eat too and what they eat are insects.  Or maybe we will only use a few native plants and use more non native plants that help bees and use less water all without cramping your style.  Whether you want a low-maintenance garden or are more interested in plants that require learning how to care for them… I’ll create a plan that works for you.
  • Knowledge and Experience: I understand how different plants grow and perform and what it takes to care for them.    Lets create a thriving and vibrant planting plan for your new landscape.
  • Personalized Advice: We’ll discuss what “low maintenance” actually means to you and design a garden that meets your expectations and provides the stunning visual appeal you expect from a landscape designer.

Low Maintenance Ornamental Grasses for Your Portland Garden: Part 1 of 3

Creating Stunning Landscapes with Ornamental Grasses: Expert Tips from a Landscape Designer

Drought tolerant and colorful N.E. Portland front yard boasts ornamental grasses like Blue Fescue.

As a landscape designer, one of my favorite elements to incorporate into a garden is ornamental grasses. Not only do they provide year-round interest, but they are also incredibly low maintenance and many are drought-tolerant. Grasses visually tie the plants in the garden together and add a calming influence.

I’m excited to share some insights and tips on using grasses in Portland landscapes and how to keep them looking their best.  The grasses I am talking about today are available at most garden nurseries and are perfect for creating a striking, low-maintenance landscape.

Fescue Grass: Elegance in Blue

Festuca glauca – Blue fescue is a stunning choice for any landscape. It’s soft blue hued blades add a touch of elegance and contrast, especially when paired with vibrant perennials like sedums. (They work with so many low water plantings.)  Here are some important tips you need to keep your fescue looking its best:

  • Planting: Space them further apart than you might think – at least 24 to 30 inches. This allows them to grow and shine without overcrowding.  Low ground cover plants (under 5 inches) can be planted close by and creep right up to the grass.
  • Maintenance: Mostly, you’ll just need to comb out the dead foliage in the spring with the occasional spruce up as needed.  When they get too big or start getting floppy, split them (very few people do this anymore), or just replace them entirely. They typically look great for about 3 -5 years assuming you didn’t overwater or over fertilize them which can cause rapid growth. I’ve never fertilized mine.
  • Water Needs: Once established, fescue has low water needs.  Figure out how you will water this area much less than other areas of your landscape.  If you can’t cut back the water using your irrigation system without damaging other plantings, try re configuring your overhead spray irrigation or close off the section of drip tube by replacing it with tube that has no holes in it.  (The term ‘established’ means the plant has been in one place for a full year or two.)
  • How to Kill this Plant:  Water it every day in the summer, over fertilize it, or plant it in a low place where winter water will puddle which will cause root rot.
  • Companion Plants: In this garden I used sedums, hens and chicks, and lower water perennials like Rudbeckia (black eyed susan) which are excellent companions.  The low sedums and succulents fill in around the grasses and add bursts of color. Other low water perennials such as colorful salvias, penstemons and blanket flower (Gaillardia) work well as do dwarf pines or other low water dwarf conifers.

Low Maintenance Reality

Even though you may need to replace fescue every 3-4 years, I still consider them low maintenance.  Sometimes I use fescue as a temporary planting, removing them once long term plantings such as dwarf evergreen shrubs have filled in and reached a more mature size.   Other times I deliberately use fescue for the long term vision with the client knowing they will be planning to replace them as needed.

Low Maintenance Fountain Grass: The Steady Eddie of Ornamental Grasses In Your Portland Garden Design

Portland area residential landscape designer.

Fountain grasses planted with late flowering Italian lavender create great textural contrast and cascade down this dry hot slope showing early fall color.

Fountain Grasses: Versatile, Vibrant and Low Water

Fountain grasses are popular for a reason – their graceful, often arching foliage and feathery plumes add movement and texture to any garden. They work beautifully in both formal and informal settings and look great with a variety of plants:

  • Commercial Appeal: Fountain grasses are often seen in commercial plantings, but don’t let that deter you. In residential gardens, they pair wonderfully with pollinator friendly naturalistic garden plants like heather, lavender, shrubs and many more pollinator friendly perennials that are stunning with fountain grasses.
  • Crowded Beds: When your planting composition starts to look crowded, it’s time to split or thin out some of the grasses. Many grasses including fountain grass need to be split every 5 years minimum.  If you overwater they may flop and they will need splitting sooner.  Splitting or thinning out some grass plants keeps the planting composition looking the way we designed it and avoids having the plantings grow into each other.  Crowding spoils the beauty of the different plants shapes and how their distinct shapes contrast with each other. I praise the faster growth of grasses over shrubs.  Using grasses means we don’t have to wait 5 years or more for the planting scheme to come together.
  • Versatility: Fountain grasses can fit into various garden styles, from modern to cottage. They’re also a great choice for adding height and interest. Last of all they can be used as temporary plantings while waiting for trees and shrubs to mature.

    Drought Tolerant Planting:  This plant handles lots of sun, and heat in Portland.  Once established most fountain grasses will take plenty of heat with a minimal amount of water.  These past two summers we have had high temps for longer periods than usual so the grasses next to concrete may need occasional deep watering to prevent scorched leaves.

Remember, even commonly used plants can create stunning effects when thoughtfully paired and integrated into your landscape.  Commercial plantings typically use one kind of plant en masse which is often kind of boring and doesn’t provide the diversity our pollinators need.  Pairing fountain grass with dark red hens and chicks and drought tolerant heather (like Calluna vulgaris ‘Mrs Ron Gray’)  is an eye catching combination.

Problems with Fountain grass are similar to fescue, overwater, fertilize, or plant in a heavy clay soil that is soaking wet in winter.  Dog pee can brown out sections of fountain grass.  This urine damaged section often dies out and it doesn’t recover.  I never set them close to the public sidewalk in city front yards with lots of dog walkers.  Some neighborhoods have a lot more dog traffic than others.

Landscaping A Mixed-Use House & Office Property in Eliot Neighborhood: Part 2

Posted by Landscape Design in a Day

Including Existing Trees & Plants In Eliot Neighborhood Front Yard Landscaping

Before landscaping picture of eliot neighborhood Portland home. Includes 2 existing boxwoods that will be kept.

Existing overgrown front yard in N.E. Portland’s Eliot Neighborhood . Our new planting plan will showcase this bungalows’ best features.

When revamping a landscape I like to start with the existing trees.  The tiny front yard of the Eliot Neighborhood property features two prominent trees: a young Dogwood, approximately 12 feet tall and wide, in the lawn area, and a young Serviceberry, about 10 feet tall and wide, situated in the parking strip.

Plan for the mature size of your trees

When evaluating trees in a landscape, I can realistically envision what size they will be in 10 or 20 years; most homeowners have a disconnect from what the tree tag says about growth rate and size when they buy the tree.  So, happily in this case, the trees my client planted 5 years ago can stay with a bit of professional help.

An example of mature Dogwood trees shaped in the form used at the Eliot Neighborhood Portland landscaping project.

This is  a similar form of tree now as mature Dogwood trees in N. Portland. These very mature trees  +30 years, were slowly limbed up a long time ago.  Look at the nice big trunks that developed.  Never remove lower branches from a young tree without knowing what you are doing.  You can stunt their growth forever.

Dogwood tree at Eliot Neighborhood Portland landscaping project.

This fairly young lovely dogwood tree will grow into the parked car area in the near future. It’s beautiful with all its lower limbs isn’t it?  N.E. Portland parking strip.

Professional Tree Pruning

Leslie already has an arborist who comes every year and he is pruning our Dogwood with minimal cuts due to its young age.  But now that we are putting a path between the dogwood and the house, he will come in and prune some additional low branches out so we can walk through this area to the office. Eventually this tree will be crown raised also called limbed up.    My photos give you a better idea of how big these trees get.

Practical Tip for DIYers: Avoid pruning young trees too early. I generally advise against any pruning for the first two years after planting and then only very minimal cuts if at all. This ensures the trunk develops adequately.  Too much pruning can stunt your trees growth and cause harm to its structure. If your tree is tiny, wait until it has developed a much larger caliper trunk before limbing up. This process, is typically known as “lifting” or Crown Raise .  It involves the removal of some lower limbs by a certified arborist.

Plants

The backdrop features a trio of  golden Italian cypress, while the garden itself includes a peach-toned rose and perennials in Leslie’s favorite colors; sky blue, apricot, lavender, and strong pinks.   Leslie knew exactly where she wanted her apple tree Belgian Fence  (this is a pruning technique similar to espalier) and it will be part of the barrier for the west side of the backyard.  I selected compatible plants, such as Echinacea ‘White Swan,’ and several fun self seeding annuals (Love in a Mist also call Nigella the sky blue flowering form will be seeded into this bed.)   California poppy and honey scented alyssum are some of the self seeding plants on our list.  Self seeding annuals and bi-annuals like Forget Me Not seamlessly integrate the garden.

 

Example of Lady of Shallot Rose that was planted at the Eliot Neighborhood landscaping project.

Selecting a rose is tricky.  While trial and error might be fun for some, most of my clients want me to pick for them.  Leslie wanted a fragrant peach apricot toned rose that is disease resistant.  For some reason there are very few disease resistant roses that are in this color range and that are also fragrant.

The rose I recommended is called Lady of Shallot and the flower changes color as it matures showing yellow, apricot, orange and warm pink.  It is fragrant, disease resistant and can be 5′ tall. I have several clients who now feel this is the best rose ever for its beauty and fragrance.

Leslie was delighted with the backyard garden design, appreciating the magical customized garden we created.
