Colorful Four Season Plant for Portland Residential Landscape Designs

North Portland residential landscape design for year round colorColorful Four Season Plant for Portland Residential Landscape Designs

I like to use Nandina as a colorful four season plant for my Portland landscape designs.

Advantages

The foliage is colorful year around.

Very low maintenance plants if you know the cool pruning tip.

They are easy to prune successfully so you can keep them for years.

Nandina varieties fit multiple diverse needs in the landscape because they can be small (18″ to 24” tall) or up to 8 feet tall.

They thrive in half or full day sun.  Deer don’t typically eat them.

People prune it wrong and then it’s so ugly they remove them – this is so easy to avoid.

It’s not a successful shade plant and will look leggy and sparse in the shade.  They will look so bad they will be removed.

People think Nandina is drought tolerant and they don’t water it in the summer……….this ends badly.

Nandina (from China) doesn’t feed our native insects; therefore, overusing it limits food for our native bird population.  I like to select at least a few native plants for companions.

Is this plant overused? Some garden designers snub the Nandina plant because it is used in commercial landscapes. Nandina is useful to my Portland residential landscape design clients who want low maintenance landscapes.  With the right plant partners Nandina can sparkle in a home landscape.

North Portland residential landscape design for year round colorHow I Use Nandina in Garden Designs

Nandina domestica – Heavenly Bamboo (not related to Bamboo)

There is a variety of Nandina to fit every landscape:

  • 6 to 8 foot tall  ‘Moyers Red’ or 4 to 6 foot tall ‘Plum Passion’ dress and soften an expanse of fence, hide the hot tub or garbage area nicely
  • 2 to 4 foot tall ‘Sienna Sunrise’, ‘Moon Bay’ or ‘Firepower’ work well in foundation plantings and entry areas.

Use a tape measure on planting day, assume the size info on the plant tag is being modest and give your plant more room to grow.  Some varieties of Nandina will grow 3 to 4 feet wide.   To keep your Nandina from getting too wide, I suggest pruning out entire canes at the base of the plant once a year.  For varieties that are listed as 3 to 4 feet wide, plant it at least 30 inches off your path.

A new variety called ‘Blush’ is typically 24 inches tall and 18 inches wide. The evergreen leaves turn an intense claret red and hold their color for months, longer and redder than other Nandina. ‘Blush’ was designed for the southern United States where it is fully drought tolerant. In Portland, all varieties of  Nandina including ‘Blush’, requires irrigation in summer. Multiple articles on the net enthusiastically state ‘Blush’ is drought tolerant but they do not mean here in the NW.  In the high humidity of an Alabama summer I too am probably drought tolerant…..Mint Julep anyone?

I love to combine Nandina with textured or needled plants that contrast with the narrow Nandina leaves.  Dwarf conifers, (Pinus mugo ‘Sherwoods Compact’), heather  Erica carnea ‘Adrienne Duncan’ or ornamental grasses like  Opiopogon (black mondo grass)  work well.  NW native plants, like salal, sword fern and huckleberry give  contrast and good looks.  They also provide food for native insects and for our birds who must eat native insects for food.  Pairing Nandina with typical cottage garden plants disappoints my aesthetic; there isn’t enough leaf contrast.

How to prune Nandina

The key to success with Nandina is learning how to prune it which is all about thinning the multiple canes (or stems) of the shrub.  Read more in my next blog or check out this u tube video I found to get you started.

 

 

 

Modern Landscape Design Plants for Portland

Modern Landscape Design Plants for Portland

As a Portland landscape designer I enjoy helping clients who want modern landscape design plants.

While well crafted hardscape is the key element to a successful modern style landscape, plant selection and how they are used is critical.

Here are a few things I keep in mind.  Balanced plant repetition, contrasting textures and overall shapes of plants, full season interest plantings, and low maintenance plants.  Keep in mind that the typical plants for modern style are not great for wildlife because they lack diversity.  My designs consider the clients many unique interests. A modern style design can have wildlife friendly plants included.

Here are 10 plants that work well for modern landscape design and are fairly easy to find.

Modern NW Natural Landscape Design

Emily after backyard

Freshly installed Landscape Design in a Day. Emily says, “Carol got my desire for simplicity and my style both with the plant material and the hardscapes.”

My new client Emily contacted me with two problems.  One – she needed a landscape design for her new home that would be pleasing and fit her space and her style.  She wanted to enjoy being outdoors in her small backyard in the summer.  She knew she didn’t want lawn and she wanted entertaining space.  She had a small terrace outside the kitchen door which is certainly big enough for a cuppa coffee, but it didn’t feel naturalistic and certainly wasn’t big enough to entertain.

Two – no matter what sort of landscape design we did she would need regular landscape maintenance.  In addition to finishing school, she spends a significant amount of time in France with family.  Lots of people say they need low maintenance.  Emily really needed low maintenance and a professional gardener who would not trim her Japanese maples into lollypops in her absence.

Dziedzic before backyard

Spring of 2016 Emily’s new landscape was overrun with weeds.

When she called me late spring of 2016 her landscape was completely overrun with weeds, and her plants (recently planted fall of 2015) were struggling.   Emily is an affectionado of minimalist design. Her ultra modern Westmoreland home is designed for renting out the bottom floor and she has a tenant. Emily loves ferns and Japanese maples. She prefers green leaves to the overly colorful variegated designer plants. She loves a woodsy naturalistic style for her plantings but wanted a minimalist modern style for any hardscaping.

Tough Environment for plants – Dry Shade

Three huge maple trees in neighboring landscapes created deep to dappled shade.  In summer they took all the water and in winter they buried the landscape in pounds of wet mucky leaves.   Fall clean up with Oregon Bigleaf maple starts in December.  It is not the romantic vision of a person wearing a light sweater whistling and raking up dry pretty leaves. You’re wearing rain gear and using a shovel lifting up pounds and pounds of wet muck.   Many plants would simply rot and die.  I would need to carefully select plants that can survive being buried by such a deluge of leaves. This was a tough environment for plantings.

Dziedzic acer-japonicum-aconitifolium

Emily loves Japanese maples. We selected Acer Aconitifolium ‘Full Moon’ Japanese maple for her shaded backyard.

Design Decisions

On our design day we focused on the backyard. She had one window on the second floor (the kitchen window) and I selected a special Japanese maple, two king-size ferns and some small evergreen shrubs to see in winter. The Japanese maple has both a hot spring leaf color and strong red fall color.  It was a lovely if obvious choice.   Her downstairs tenant had an egress window so I kept the plantings low to keep all the available light.

Privacy Plantings

To create privacy between properties we used three small evergreen trees with tiny leaves to contrast with the Oregon Bigleaf maple.  The rest of the plants were selected for summer interest because they would not be seen in the winter from the house.

Materials create the style

When I am designing a modern landscape, materials are everything.  The new modern landscape design, which is actually not all that new anymore, can become a cliché of itself.  Straight line paths without proportional balance look uninviting and cold. We used a warm gray HydraPressed concrete slab that is the epitome of modern style and will last forever if properly installed. We created two patio spaces and connected them with wide paths.  It looks like one space with plants flowing in between. This is a lot of hardscape for a backyard so you might think it would look harsh. Plantings will cover every square inch of soil and create such a lush and full complement so that the patios are fully integrated visually.  It’s a balancing act between hardscape and planted space.  Another help toward a serene and simple look is the lack of lawn.  Lawn, patio and plantings in such a narrow landscape wood tend to create a busy feeling and of course lawn would not thrive in such a shaded woodsy environment.

100 shades of green

It was important to honor Emily’s love of green leafed plants but in order to achieve the lushness needed to integrate the design, I had to find a way to provide a variety of textures (leaf shape, sheen, shade of green, habit of plant branches, etc.).   My ideal for Emily’s garden is that you could take a picture of it with black-and-white film and it would still look incredibly beautiful because of the contrasting textures and varying shades of green.

Garden Design for Gardeners

Japanese maple – Acer Palmatum ‘Shindeshojo’

Because Emily loves Japanese maples she will have a succession of seasonal color changes to entertain her from spring to fall. The plantings we used are fairly low water once mature but it would be difficult to establish the plantings without irrigation because the huge Oregon Bigleaf maples roots will steal water from the new plants. With Emily’s school schedule and traveling, an irrigation system was necessary for long-term success.  No one wants to saddle their tenant with the job of hand watering the landscape.

Emily’s comments

Dziedzic backyard during wheel barrow

August of 2016 was too hot to transplant Emily’s favorite maple. The contractor and I redesigned the hardscape layout so we could leave her existing maple undisturbed.

Emily is very happy with the design “I absolutely love the garden and am so excited about it.  It’s wonderful.”

Willamette Heights Hillside Landscape Design

Willamette Heights Hillside Landscape Design 

WM sized Ericson arah after backyard photos 11 2016 (7)

New boulders define the original pathway leading to Forest Park from the backyard.

Willamette Heights Hillside Garden Design

The Willamette Heights neighborhood of NW Portland is special for many reasons. The architecture of the grand old houses, views of the city, Mount Hood and that it is surrounded by Forest Park.  There is a simple 2 lane bridge for traffic in and out of the hillside neighborhood.  It feels private. My clients happened to have a path that leads into a secluded part of the park from their backyard. It’s an old neighborhood with serious garden history. It was the playground for the famous landscape architects Wallace Huntington and Barbara Feeley. I’ve been privileged to create many residential landscape designs in this neighborhood including the restoration of the Bertha Cooper Garden, renamed Cooper Phillips Garden in honor of the builder that saved it from destruction.

My client grew up here.  She and her husband bought a beautiful craftsmen house (1905) about a mile away from her childhood home with views and a private path into Forest Park. She had the clearest vision for what she wanted that I have come across. Her first priority was finding a designer who would fully understand her ideas and hold true to them in the design.

Portland Landscape Designer with smaller ego

She called me looking for an experienced landscape design collaborator to help her create and install her vision. I came by to meet her and see the property. We started in the big kitchen with tall beautifully framed windows and French doors to the backyard. This room was the heart of the home. We had views into the woods which were uphill from the level yard.  The landscape was divided from the woods by a low rustic rubble rock wall. She knew what she wanted and it was not typical. For starters, she didn’t want the rustic rubble wall rebuilt or made more substantial. She wanted a large flagstone area that could be play area and entertaining area. She needed me to take her idea and make sure it didn’t end up looking like they had paved the backyard.  She wanted the man made to melt into the nature made forest.

Low Maintenance Garden Design

WM sized Ericson before black plastic wasteland

The backyard weeds had exploded and the first winter turned the yard into a mud pit. It was too shady for grass.

It is a large landscape overall. They had put in a lot of time and effort with the front yard and that was working well.  The backyard weeds had exploded and the winter rains made a mud pit. They installed 2,000 sq feet of black plastic.  The black plastic was not happy making but she didn’t have the time or the inclination to make the entire property her hobby.

The plantings needed to be simple both for style and for practicality. Since the woods were wonderful all on their own, it was the wasteland that lay between the house and that wall that would be our subject.

What’s the Style?  Minimalist NW Natural 

We want simple lines and minimal plantings to keep from distracting us from the woods. Just like the interior, the exterior can be simplified without going too modern. In the early 1900’s there was a huge social change called the Arts and Crafts movement. People were suddenly interested in native plants, hiking, sleeping outdoors…these were big changes from the Victorians who worried that night air was harmful to your health. A craftsmen house, even a grand one like this looks great with simple  NW natural style plantings.   The minimalist style of using fewer varieties of plants also makes it lower maintenance which was another top priority for her.

The pathway to the woods

something about Arah working with Landsape East and West

There are 4 different garden rooms, the path to the woods, a small lounging area, a play area and an area for a large rustic picnic table.

The pathway to Forest Park was just waiting for my attention ………I say take a good thing and make it more dramatic, bigger and make it a destination by adding other elements that enhance and point to it. There was an earthen path already but I moved it over a few feet, added rustic stone steps up to the path and a few large sitter rocks that added drama to this gateway. It’s going to be a great place to hang out for big and small people.

Make the rooms work

She wanted a big flagstone patio.  I added in the shapes of the planting beds being careful that each flagstone area was big enough to be useful as play area or sitting area. The shapes of the beds keep the flagstone patio from taking over visually and the spacing between the flagstones grew larger as it got further from the house.  The views from the window filled kitchen were kept focused on the woods by using low plantings with only a few verticals.

 The Installation Process

My client directing placement of flagstone.

They interviewed three landscape installation companies and selected a well known company but not one I worked with. Hillside landscape designs cost more to install because there is always  additional expense for bringing materials in. Having an experienced company to manage the logistics was important.  They used a crane to deliver all the materials even the yards and yards of crushed rock. It’s wasn’t practical to bring anything up the long stairs from the street.  She worked with the contractors herself and used me for advice. She called me in to work with her contractor on the boulder placement and to fine tune the flagstone placement to ensure each area was the right shape for maximum play and entertaining space.

Client’s Comments
Her final note on the design drawing……..”I went through the plan in detail and really like it. I feel like you ‘got’ the low-key NW, drought tolerant, blend into forest part style really well. I am excited to move forward with our design.  Carol gave me referrals to 2 great landscape contractors so I was picking from a good pool. The final results are both a pleasure and a great relief.   Yes the mud is gone but more importantly now I have a large outdoor living room that is very attractive and usable.  I also look out from my kitchen and I see my design, the one I dreamed up.  Carol helped me make this vision real. I appreciated the flexibility of her Landscape Design in a Day process.”

Plantings for Parking Strips

This article describes a very attractive but low maintenance planting and hardscape design for a parking strip in NE Portland.

Making great access across a strip for dry, non-muddy feet is practical and provides an attractive low maintenance landscape that adds tons of curb appeal to your home. This is effectively demonstrated by my design at NE 35th and Stanton.

Easy Care Parking strip adds curb appeal

!st year planting at parking strip NE Portland

The strip faces west, and people rarely park there.  The strip, which has mature suckering ornamental pear trees, create some cool for my client’s house in the summer, but are difficult to plant under because of root mass.  The trees also don’t share water or nutrients and have small but abundant leaf drop in the fall.  Selecting underplantings that don’t have to have every pear leaf removed prior to winter is simply smart and pays back every year in less work.

After creating a soft shape of practical hardscape, I selected a combination of plants that  will create interest for the entire year.  My client doesn’t have to think much about the plants because they are automatically irrigated with a drilled emitter tube system that is underground.  The irrigation also helps the plants compete with the pear tree roots. Over time, even in difficult conditions, the plants will need less and less water.  My client takes her weeding seriously, so even in the very first year, this planting is already filling in.  The style is very Northwest – natural and serene and adds to the curb appeal of the entire landscape.  By the third year, the weeding should be quite minimal as the plants have already spread and thickened, discouraging weeds effectively.

There are several things that need to be considered prior to designing an attractive solution for that difficult parking strip in front in your home.  On the top of the list are:     1) the sun direction;  2) whether you have trees in your strip and; 3) whether people often park near the strip.  Other things that are equally important to consider are the utilities near the strip – such as water meters, downspout connection to the street, electric and gas lines, fireplugs, and lastly, the rights of people, especially that of your neighbors to park and access the sidewalk. Remember that the parking strip actually belongs to the city or county.

Typical design issues such as soil preparation, irrigation, and what style of planting that will look best with your home also figures in.  A parking strip is the foreground view of your home, so it matters what it looks like year round. And last, but most important, is how it will look in the internet photo when it is time to sell your home.
