Pruning Nandina easily for Portland residential landscapes

Pruning Nandina easily, the perfect low maintenance plant, for Portland residential landscapes

Low Maintenance Shrub (Nandina) for Portland Residential Landscape DesignI promised I would follow up from my last blog about Nandina domestica – Heavenly Bamboo and how seriously low maintenance they are.  I’ll give you my easy pruning trick for Nandina and you’ll be all set to use this shrub, a low maintenance year round beauty, in your Portland landscape.

What’s the problem with shearing Nandina?

If it’s so easy to prune why do we see so many sad looking Nandina out there? People try to prune them like a boxwood hedge.  Boxwoods have a typical shrubs’ woody structure and little tiny leaves.  They can be sheared and look pretty good.  Nandina are a multiple cane plant with a compound leaf composed of many oval shaped leaves.  The best way to ruin their appearance is to shear them into little round balls or squares.

Ugly Nandina in Portland Landscape Need Pruning TipRestore leggy sparse leafed Nandina plants

These photos illustrate embarrassing ugly examples of Nandina out there in commercial and residential landscapes.  These sad plants at my local bank have not been pruned at all.  If yours look this bad, hold off on tossing them.

Portland Landscape Designer's example of poor pruning techniqueWe could correct these ugly leggy Nandinas’ appearance in one year by applying the pruning technique I have illustrated here.  These Nandina domestica ‘Gulfstream’ could look amazing with regular irrigation and pruning once every year or two.

My drawing “Fix Leggy Nandina” illustrates restoring a Nandina that has developed leggy bare canes (or stems if you like).  It has no foliage at the base of the plant.

The Cool Trick to Pruning Nandina

The simplest pruning technique is to cut 1/3rd of the canes to the ground and call it done.  This technique will get you a much better plant once the new canes sprout. I control the height by selecting the tallest canes to remove.

You can take your easy pruning a step farther and select another 1/3rd of the canes and cut them at different heights.  If you only have 3 canes to work with it would look like my “Fix Leggy Nandinas” illustration and in one year it would have a new cane with leaves on it sprouting from the ground and the stem you cut back would have new stem and leaves above where you made the cut.

When to Prune Nandina

You can prune nandina any time of year here in the Pacific Northwest.  I like to remove canes to use for holiday table decoration in the winter but only from a robust plant with lots of canes.  I  prefer to do restorative pruning (such as in my illustration “Fix Leggy Nandina”) as early as March or as late as May.

How to Prune Dwarf Nandina

The technique is mostly the same, but dwarf varieties like ‘Firepower’ need almost no pruning to contain height and if they get enough sun, they rarely get leggy.  The plant can get too wide so I like to thin a few canes out at the bottom (or up to 1/3rd of my canes) every year to keep the plant from ever getting too wide. This allows the little plant to continue serving as a colorful year round foundation plant for the long term in your landscape.     Here is a good video to illustrate pruning the dwarf varieties.

Portland Garden Designer’s Holiday Gift Ideas

Portland Garden Designer with Favorite Tilly Hat

Portland Garden Designer’s Gift Ideas

Here are my favorite items to give as gifts.  The Tilley hat, favorite therapeutic hand cream, inexpensive gloves, Garden Design Magazine, plants as gifts and pruning tools.

The Tilley Hat

You can buy a Tilley hat at REI, Bonnet in NW Portland at Bonnet or on line.  I love my summer (Hemp fabric) Tilley hat because whether it’s picking peaches or playing with my dog, my hat stays on, it’s easy to wash.  I am around a lot of dirt and it is still a cream color. It protects my face from the sun (is recommended by some dermatologists for that purpose) and it’s not too hot to wear in the summer.

Hand Care

http://www.crabtree-evelyn.com/collections/gardeners/60-second-fix-for-hands/Gar-Fix-For-Hands.html

Great Hand Care Product

My favorite hand care product is Evelyn and CrabTree  60 second fix for hands.  It has 2 products, the Ultra Moisturizing Hand Therapy and the 2nd product called Hand Recovery.  There are more heavy duty hand products out there but this one has a light fragrance and penetrates the skin.  It’s therapeutic.  I handle art supplies and  garden so I like a good hand product.  Andalou Naturals Hand Cream is also nice but doesn’t penetrate the skin nearly as well.

Gloves

I love having A LOT of gloves.  I’m a person who misplaces gloves and as a child I resented that nursery rhyme about the kittens who lost their mittens because clearly I was going to be one of those kittens.  I have 20 pairs of inexpensive work gloves.  Gloves are great stocking stuffers.

Plants As Gifts

North Portland Garden Design Itoh PeonyNorth Portland Itoh Peony in Garden Design

Itoh Peonies are so popular this year (2017) that wholesale and retail sources sold out completely. The variety called ‘Cora Louise’ was the most popular and the first to be gone from retail and wholesale sources.   Why are Itoh Peonies special?

They are tough enough for low maintenance landscapes so they are not just for serious gardeners……..and serious gardeners have simply lost their minds over these beautiful and sturdy stemmed plants.  If you have a gardener in your life who loves big colorful flowers……..this gift will express your love for years. A gift certificate to a local retail nursery with a photo would do it. Expect to spend $125 to $150 for a 5 gallon plant.  Here are links to Portland Nursery gift card, Cornell Farm gift card and a video explaining more about Itoh Peonies.

Another popular plant for gardeners that you can buy in December are Hellebores and the big garden nurseries will have these for sale starting in December through March.  These are somewhat toxic so don’t leave them where small children or pets can get them.

Pruning Tools

Pruners –  I love Felco and Corona tools the best.  Cheaper but very lightweight pruners and clippers from Fiskar are popular too.  Here is a good one called PowerGear.  Felcos are for the gardener in your life.  I still love my #6 Felco hand pruner for smaller hands and think they fit most women better than a #2 Felco hand pruner. Utube video on how to select ergonomic pruning tools for people who want to learn how to prune their trees and shrubs.  The right tools make a big difference in the outcome for your plants.

Ornamental Grass in the Landscape

Low Maintenance Grass for Your Landscape Design

Low maintenance xeriscape landscape design with good grasses.

Good grass like Pennisetum Alocuroides ‘Little Bunny’ – Dwarf Fountain Grass is drought tolerant along with Stepable Thymus Pracox ‘Elfin Pink’,  a nearly flat Thyme groundcover.

Designers love to use ornamental grasses to add structure and seasonal interest. They have instant appeal and we designers are suckers for plants that soften pathways and make a dramatic statement.  They are a staple in modern landscape style. However, grasses have a bad reputation.

Grasses for those Who Hate Weeding

I’ve had to reassure more than one new client the grasses I use don’t spread or reseed. My years of experience with plants means I’m slow to use the untested new plants, including grasses.  I’ve seen too many new industry introductions (plants) that looked like a good thing turn into thugs after a few years in a garden. Most of my clients say they dislike weeding over all outdoor chores so I shun plants with potential for adding weeding to the maintenance list.

Researching New Plant Material

I’m writing this blog during my winter break when I research new plants and prepare for another busy year designing Portland gardens. I confess to being a teeny bit bored with my tried and true grasses.

I was quizzing a couple of my landscape designer buddies about new ornamental grasses.  I discovered they are sticking to the tried and true grasses and not using any new risky plants in their designs either. Here I was thinking they might be experimenting with new plants and that I was getting behind! Nope they are nervous nellies about using an unknown too.  We see what happens when a client buys some new cute plant only to have it take up a forever place all over the property…

Beautiful Bad Grass? – Mexican Feather Grass

Designers are concerned about grasses that seed and make weed problems for our clients.  The Mexican Feather (Stippa Tenuissima) Grasses are highly desirable because they are so finely textured the slightest breeze sends them into graceful sway. They are over the top beautiful! They can seed some or a lot and they are the darlings for xeriscape or low water gardens.  This grass is perfect for many dry and hot natural areas in California and (so naturally enough) it is on their noxious weed list.

This Bad Grass is so good in Modern Design

I don’t use Mexican Feather Grass but I have wanted to…they are unique, beautifully blowzy and are a stunner for modern minimalist designs.   I have a local gardener pal who has them in her large Portland modern garden design to fantastic effect. People who are gardeners with a capital ‘G’ may keep up with weeding out the unwanted grass seedlings. Still, all it would take is a distraction, health problem, or too much over time, and this grass would be seeding into a new planting bed at your property and then your neighbors! Part of hiring an experienced designer is the safety margin we bring to the design process.

Beautiful Good Grass Blue Grama ‘Blonde Ambition’ 

Low maintenance plant Blonde Ambition for Portland landscape design.

Bouteloua Gracilis or Blue Grama Grass ‘Blonde Ambition’ moves in the breeze like living art.

Bouteloua Gracilis or Blue Grama Grass ‘Blonde Ambition’ relieves my boredom in a flash and is a great substitute for the wildly popular Mexican Feather Grass. Discovered by David Salman of High Country Gardens, this plant has all the drama of Mexican Feather Grass but won’t seed around.   It’s very dramatic looking with a flower head that juts to one side like an eyebrow.  It’s evergreen and moves beautifully in the breeze so it’s not just a plant, it’s living art.

Low Maintenance Landscape

Cut it down in February to two inches tall, scuff the crown of the plant and pull away any loose grass stalks from the crown.  It will thrive in a lighter soil mix with lots of sun.  It prefers no fertilizer, low water and can be fully drought tolerant after established.  To kill Blue Grama Grass, plant it in heavy clay and over water it.  I’m excited about adding this good grass to xeriscaping planting plans in the coming year.

Ferns for Portland Landscape Designers

Ferns for Portland Landscape Designers

I’ve been following Judith Jones and her career as a fern expert extraordinary before social media existed.  She’s been my fern guru for 20 years and I’ve tried to catch her lectures when she comes to Portland at Joy Creek Nursery, HPSO plant sales and garden shows.  My favorite Judith sighting was at the Seattle Flower and Garden Show when her show garden as the set for the Flintstones.  She was dressed as Wilma complete with a bone in her hair.  There was a dozen or more 8’ tall tree ferns and a 20’ tall volcano.  It looked like a real tropical fern forest.  It’s still my favorite show garden of all times.  She and her nursery Fancy Fronds have been my source for ferns in my designs.

She gave a special program for ANLD Portland Landscape Designers the other evening. She has continued to evolve and had new plants for me to consider as well as highlighting my old favorites.   It was such a pleasure to see her and learn more about ferns for landscape designers.

Tracys Hybrid Maidenhair – Adiantum x Tracyi

Is it possible to have a new fern?  This maidenhair was discovered in the 1900’s instead of 2000 bc which makes it new in my book.  Tracyi is a natural cross between two California native deciduous Maidenhair ferns and oddly enough it is evergreen.  Clients like a plant with long seasonal interest. The leaf or pinnae is cute, it has little dimples in the edge of each leaf.  The plant is a foot tall and like many Maidenhair ferns, the texture of the plant is what people notice most.  The best place to buy it is Judith herself at www.fancyfrondsnursery.com   I will list it in the shade category but many maidenhair fern can take some sun and become low water plants over time.  Typically, they are listed for moist shade.

Peacock Moss Modern Landscape Style

Kraus’ Spikemoss – Selaginella Kraussiana is a low ground cover fern that is underused. Some think it isn’t cold hardy for Portland, Oregon. Not true! I have it growing outdoors in a container where it’s handled many winters. It’s thriving in boulder crevices up in Willamette Heights. Plant it where it will have good drainage and light shade.

Kraus’ Spikemoss – Selaginella kraussiana ‘Gold Tips’ 

My descriptive words for Spikemoss are baby chick fluffy, with evergreen piles of adorable pettable  texture.  Judith feels it is underused and recommends it for Portland designers.  Don’t get confused and purchase Peacock moss, Selaginella uncinata because they are devoured by slugs.  I’ve been using Spikemoss for years at garden shows to dress up my pottery which is how I know that the millennial generation loves it.  They come running into my booth to pet the moss and ask if it is real. Spikemosses are not true mosses and are classed with ferns because they have a vascular system and moss doesn’t.   I’ve used Spikemoss in between boulders and I love the effect. My advice for boulder plantings is plant twice as much as you need, use a mix of compost, clay and sphagnum moss in the crevices. Don’t plant them at the base of boulders; they won’t get enough light.  Where it succeeds, it is eye catching with chartreuse fluffy fans against gray boulders. It has succeeded planted under my  (containerized) Dwarf  Vine Maple for 6 years so cold isn’t an issue.

Narrow Planting Beds

Photo credit Fancy Fronds, Judith Jones Narrow fern fits urban gardens (Scaled Male Fern Dryopteris 'Stableri Crisped')

Scaled Male Fern – Dryopteris ‘Stableri Crisped’ – Grow this fern in front of a long fence to make the fence subordinate to the landscape instead of the most prominent feature.

Ferns for Narrow Planting Beds – Narrow Golden Scaled Male Fern-Dryopteris affinis ‘Stableri’ which has no crests and ‘Stableri Crisped’ which has curled and crimped pinnule margins.  Think amazing texture!   Judith suggests these for narrow planting strips in general and in front of tall fences in particular.  My experience is that builders and concrete contractors often create front walks that only leave a skinny strip for plants.

Imagine a  6′ tall fence with, you guessed it,  about 15” to plant in.   It’s a problem for homeowners and even designers struggle finding plants that fit this situation.  Jack hammering out the front walk and starting over with a new one is the best thing if there is space for other options and budget.  The rest of the time we find the right plant that will fit that location for years without our clients needing to do much.  Can you imagine a fern trimmed into a lollypop?  We are trying to avoid that sort of business!!  Sigh…….. These handsome ferns could live for decades in that narrow area as long as the soil drains reasonably well.  These ferns are also my favorite for visually making the fence subordinate instead of prominent. The narrow vase shape also makes them perfect contrast partners to plants with large leaves like Hosta or Fatsia in larger planting beds.

Foundation Plants

Sword Leaf Holly Fern – Polystichum xiphophylum  and Makinoi’s Holly Fern – Polystichum ‘Makinoi’  

These two ferns could become your new regular use plants in designs.  They are evergreen, not as tall as many ferns and look good in foundation plantings.  Place them in partly shaded and shady areas.

Olive colored foliage makes this fern unique for Portland Landscapes

Makinoi’s Holly Fern – Polystichum ‘Makinoi’

Sword Leafed Holly Fern – Polystichum xiphophylum is neat and small at 15″ tall.

Makinoi’s Holly Fern – Polystichum  ‘Makinoi’ –  Olive, straw gold and russet fern with lustrous fronds is beautifully different than other ferns. Judith says it like this: “There is a reptilian sheen to the olive-green linear-lanceolate fronds which blends subtly into the varied straw to chestnut colored scales cloaking the supporting framework.”   It’s typically a 2-footer and evergreen or ever olive.  Some filtered morning light is okay but this fern is not for sunny areas.

Shade Garden Combination of fern and hosta

ANLD Member Rick Hansen design Arachniodes Standishii – Upside Down Fern in 2015 Designers Garden Tour. Note the color echo achieved by matching the mid green of the fern with the mid green leaf edge of the hosta.  See the contrast from the ruffled texture of the fern with the smooth hosta leaf.

 

 

Big Drama Fern

Upside Down Fern – Arachniodes Standishii  –  It’s not an upside down plant but the way the little pinnae are organized is opposite of all the other Arachniodes ferns in the world.  What I  care about is that it is cold hardy here (native to Korea and Japan), has an over the top lacy pattern and is easy to grow.  It’s semi evergreen.  It can take a little direct morning sun, typically place it in filtered shade with some deeper afternoon shade.  Plant it in front of other plants for a peek through the lace curtain effect.  It can eventually get large (4′ tall and wide) and I am trying mine on the north side where it will get sun until noon in mid June.  I’m pushing my luck a bit so we will see if it scorches and if so how long it takes to recover.

After the lecture, I bought plants. Even in my near senior status I felt that good old plant lust rise to the surface.  I usually don’t indulge in buying plants at lectures.  Managing all aspects of my landscape design business doesn’t leave me a lot of time for my former hobby of gardener and plant enthusiast.  I must be careful that I don’t kill plant material purchased in a state of amnesia about the reality of my life.  I bought these 5 ferns:  Tracys Hybrid Maidenhair – Adiantum x traceyi, Narrow Golden Scaled Male Fern  Dryopteris x complexa ‘Stableri Crisped’, Arachniodes Standishii, Upside Down Fern, Makinoi’s Holly Fern – Polystichum  ‘Makinoi’, and have lost the tag on the last one.  It’s clearly a Holly fern of some kind.

Buy ferns from Judith

My clients and I buy ferns directly from Judith off her web site or via an email. I like buying from her and get loads of advice and information when I need it. They arrive in great shape and are mostly sized between a 4” plant and a quart.  If you want bigger sizes, contact her before the spring or fall HPSO plant sale and she can bring them down for you.  Your clients can buy directly from her too.

Colorful Cape Fuchsia Makes Beautiful Summer Memories

N. W. Portland roof garden with cat Cracker Jack

My cat loved to watch hummingbirds.

Colorful Cape Fuchsia Makes Beautiful Summer Memories

Hummingbirds love Cape Fuchsia for the nectar.  I love to use it in designs because it adds so much color, is easy to grow and the new varieties work well with modern and cottage garden styles.  This plant is a crowd pleaser and I use it frequently.

I planted my first Cape Fuchsia, Phygelius x rectus ‘Salmon Leap’ on my roof garden in Portland’s West Hills. It was at 900 feet and we had snow every year.  The house was designed so that the third floor master suite had easy access to and a view of my roof garden.  It had a hot tub that was 20 feet from my bed, a big overstuffed outdoor sofa with an overhead cover and plenty of Cape Fuchsia!  In spite of the colder winters, the Cape Fuchsia (native to South Africa) never flagged or failed in the 12 years I lived there.  I loved my roof garden and the only family members who loved it more were the 4 leggeds, Barley,  Cee Cee and Cracker Jack.  One particular day everyone was curled up on the sofa.  I was reading and pets were napping.  All was peaceful.  I heard a strange whirring noise.  At first I didn’t see anything unusual.  Out of the corner of my eye I saw my pets’ heads were going up and then down and then up, I saw a small blur.  What was happening?

Humming Bird Mating Ritual

We were witnessing a hummingbird mating ritual.  The male made a 90 foot oval flight pattern to within an inch of his intended.  She was steadfastly ignoring him and drinking nectar from my Cape Fuchsia.  There wasn’t even a flicker in his direction.  The buzzing sound was made by his high speed downward trajectory.  It abated on the way up.   It was mesmerizing.  It was one of those beautiful summer garden memories that I treasure.    Just us mammals all watching the entertainment together.

Cape Fuschia Varieties for Hummingbirds

If you would like to have some close encounters with hummingbirds or you just love colorful plants, the Cape Fuchsia is the perfect addition to your garden.  The best hummingbird attractors are the older varieties because they flower in the most intense coral red shades.  My favorites are ‘Devils Tears’, ‘Salmon Leap’ and ‘African Queen’, but they are too big and a bit too rowdy for a small yard.

The new varieties are more compact and a little tidier in habit.  The flower colors are available in more traditional flower petal shades.  When these new colors first came on the market I was annoyed.  I felt like they had dumbed down a great plant by removing the coral shades…….but then I saw it wasn’t an either or.  I now had more choices and that is always a good thing for a garden designer.

If you love modern landscape design style but don’t want to give up color, these new Cape Fuchsia are perfect  because they are smaller.  They look great in a mass.

Here are 2 new varieties from Skagit Gardens:

Croftway purple prince cape fuchsia

Skagit Gardens’ Croftway Purple Prince is an intense magenta.

Phygelius Aequalis ‘Croftway Purple Prince’ has that intense magenta color.  I think it looks really good with Black Mondo Grass………Morticia Adams where are you now?  It glows in the evening light.  ‘Croftway Purple Prince’ is cold hardy for the Pacific Northwest and listed as zone 6 Yah!

Phygelius Aequalis ‘Croftway Yellow Sovereign’ is 18 to 24 inches tall by 24 inches wide.  Many plants with soft yellow flowers burn in full sun but ‘Yellow Sovereign’ can take the sun and heat.

Full sun easy care yellow sovereighn cape fuchsia

Skagit Gardens ‘ Yellow Sovereign’

Barbara Ashmun, Portland garden writer has a great article about Cape Fuchsia’s.

I don’t tend to use the older varieties of Cape Fuchsia in front yards as the winter appearance is too ragged without a major trim.  If you love this plant like I do, simply cut it to the ground in mid December for a tidy look.  People who like a very tidy landscape may want to pass.  It will seem too messy for them.
