Best Hardscape Landscaping Materials for Portland Backyards

Crushed rock landscaping material for paths & friendly chickens!

Here are some of my favorite backyard paths and patios from landscape designs here in Portland!

Paths are a key element in any landscape design.  How we walk and move in a landscape is what shapes the design.  Selecting the best materials for these surfaces for function and style, makes the design come alive.

Crushed Rock is a Versatile Surface

Crushed rock fits modern and naturalistic landscape styles and is significantly more affordable than poured concrete or pavers.

It lends a soft and natural look to a NW Natural backyard landscape.  However crushed rock when crisply defined by steel edging is perfect for a modern or minimalist landscape too.

Water permeable crushed rock surfaces for your paths will allow water to find its way down into the earth instead of running off into the street and sewer.

Crushed rock is also the perfect material for a natural style garden.

Crushed rock in Woodlawn Neighborhood fits the naturalistic style of the garden.

Compacted crushed rock surfaces do not allow rainwater to filter through to the earth.  With professional grading the winter rain water can be directed away from the house and/or into a catch basin or other mechanical means of collecting water.  A licensed landscape contractor is qualified to create systems to manage winter rain water.

 

Colors of Crushed Rock

Stone step color matches the decomposed granite crushed rock in the pathway.

Decomposed granite – the names of the colors change with each stone yard which is sure confusing but here in these photos you are looking at a soft gold tan or a cream rose color.  My clients like the look and I agree it adds visual elegance to the landscape design.  I prefer the cream rose color over the gold typically.

I’m also perfectly happy with the dark gray of locally sourced basalt.  Gray looks so good with the greens, limes and golds of plant foliage and it’s more affordable than the decomposed granite.

Crushed rock was picked to compliment this backyard patio.

Irvington neighborhood backyard patio and path materials blend beautifully.

The Cons of using Decomposed Granite

After a few years you will need to top up your patio surface because it has gotten thin, and  the color you installed may not be available.  Rock is different colors from different areas or even within the same mountain.

Granite is not local and is trucked from the east coast.  This uses a lot of fossil fuels.  We have a locally sourced attractive basalt rock here in Oregon which is gray and harder than the decomposed granite.  It won’t need to be topped up as often and doesn’t cost such a high price on the environment.

Granite is significantly more expensive then local basalt.

Top Dress Planting Beds with Crushed Rock for Drought Tolerant Plantings

Crushed rock can also be used as an attractive mulch for drought tolerant plantings.  This garden in N Portland shows crushed rock all around these heat and drought tolerant plantings.  Using the crushed rock as mulch on these slightly bermed planting beds helps protect the plants from our heavy winter rain.  The rain rolls off the crown of the plants roots in the winter and adds needed oxygen to the soil.  Here are narrow evergreen Italian Cypress’ Tiny Towers’ with 2 different varieties of California lilac, fountain grass and sedums for this hot south facing bermed garden.

Crushed Rock Can be the Stair Riser

Sadly, pea gravel is sometimes used for a path, patio or even as the top dressing for a planting bed but never in my designs.  It is not crushed or angled, it is round and does not stay put.  It will go all over your yard, out into the street and can actually roll under your feet as you walk and cause falls. Pea gravel makes an unsafe surface for a stair tread.  It has a softer visual look and people fall for its’ quiet beauty and then later deeply regret using it.

Tips to succeeding with Manzanita in Portland Residential Landscapes 

How to Help Your Manzanita Thrive In St. Johns Portland 

Arctostaphylos in container at Xera Plants for St. Johns Portland

Drought tolerant landscaping in Southeast Portland

Manzanita (called Arctostaplylos – Arc toe staff eye loss) is the new cool darling plant here in Portland. The reasons why are numerous, unique “new” plant, drought tolerance, attractive in winter and all year, and there are now many diverse shapes and sizes to work with that will survive here. Years ago I only used this plant for a plant collector garden because they knew it was a crap shoot as to whether it would survive at all.   

As a Portland landscape designer I want plants that will serve many purposes in my designs. For people who are done with the overuse of Rhododendrons and Azalea and want drought tolerant plants, Manzanita is the perfect plant. Before you fall in love, I want to give you some tips for succeeding with Manzanita in Portland. They have requirements that must be met if you want them to thrive. 

Please see my previous blog “Portland Landscape Designer Advocates use of Manzanita in Xericscapes”.

Tips for succeeding with Manzanita in Portland 

Select the right site, conditions and plant companions 

Most are intolerant of summer water….clients must understand that they cannot coddle these plants, they cannot plant annuals with them for summer color, they cannot fertilize, they cannot water these plants after they are established or they will die.

Enhance Your Manzanita Health’s by Planting on a Berm 

Kinnikinnick is a form of Manzanita (Arctostaphylos) often used in Portland as a groundcover.

Ground cover Manzanita in Raleigh Hills

In many Portland landscapes planting on a berm will be necessary to avoid root rot. You will see bermed soil areas here even in parking strips. Portland parking strips (the 4’ wide ones) are a popular place for many of the new smaller types of Manzanita and for drought tolerant or xeric styled plantings. Most of the Manzanita I am using are too wide for a 30” parking strip.

 

Manzanita Planting Companions

Planting companions must have the same no water requirements because it’s hard to remember not to water one plant and that you must water the one next to it. If any kind of auto irrigation is used the first summer it must be disconnected, dismantled, hell-dismembered so no one accidentally waters that second summer.   

I select companions from Mediterranean or NW native plant palettes. Some mid west native prairie plants also work well with Manzanita. Herbs, ornamental grasses and xeric perennials like Penstemon or ice plant are easy companions and Heather (Calluna Vulgaris types) are one of my favorite for texture contrast.

Buy small plants 

It’s best to buy small plants (a one or two gallon size) and they will establish faster than a larger plant with a higher survival rate. Large sizes of these plants are not available anyway. Many of these plants will be available in a 4” pot or perhaps a quart sized pot. Smaller plants make more sense in this case but don’t expect them to be inexpensive. You are paying for all the research and extensive work to create these new plants. 

Manzanita has well formed leaves and most flower in winter for St. Johns Portland neighborhood.

Select the right Manzanita 

The trial and error approach for picking which one to buy and where to plant it is going to be very frustrating. There are quite a few new plant types to pick from and some grow very fast, some slow. Some may be pruned hard because they have a burl (what’s a burl?) and others would be ruined with such treatment.

Austin Griffiths is one of the most popular manzanita in Portland landscapes. Here is a close up of the flower buds getting ready to open in late January 2023.

Your Portland landscape designer needs to be an expert or have access to one. If you are on your own, buying from Cistus Nursery or the retail store Xera Plants, Inc. is the best way to get the expertise you need from their very knowledgeable staff.   

I talked to Alana Chau at Cistus Nursery. Here is her list of plants that will be available that I especially liked. 

 Arctostaphylos hookeri ‘Green on Black’  18” high and can handle some clay soil. 

Arctostaphylos × media ‘Martha Ewan’ is a nice size maturing at three feet tall and it can be tip pruned. It gets wide so give it room to be 4 or 5 feet wide. 

Arctostaphylos Stanfordiana ‘Mills’ or A x ‘White Lanterns’ both at 4’ tall 

Arctostaphylos Dr Hurd’ is a curvaceous 8′ to 10’ tall small tree and is planted at the entrance to Cistus Nursery 

Arctostaphylos  mewukka or Arctostaphylos patula can be pruned heavily. (They have a burl and once established they can be pruned back to the burl, for non horticultural nerds just know this means you could plant one of these closer to your walkway than many of the other varieties because the size could be controlled without ruining the appearance of your plant.) 

(We designers get excited about plants who fit into a small landscapes so we might be more excited that this burling option than you are). 

 My manzanita guru, Paul Bonine explains about burls in his article in Pacific Horticulture, Arctostaphylos for Pacific Northwest Gardens “Some Arctostaphylos species develop an enlarged area called a burl at soil level; new shoots emerge from the burl following fire or extreme drought, or from extensive pruning to rejuvenate a plant in the garden.”

Colorful Plants for Portland Winter Landscapes-New Zealand Pepper Plant

Colorful plants for Portland Winter Landscapes-New Zealand Pepper Plant    Cedar Hills residential landscape design Drimys Lanceolata is the perfect evergreen shrub

I enjoy a good hit of colorful plants year-round but especially in winter. The rest of the year has so many plant choices here in Portland it’s almost too easy for a garden designer. Winter has fewer selections for colorful plants and is a better challenge. Drimy Lanceolata – New Zealand Pepper Plant is not a new plant for designers but probably new to most homeowners. 

What’s so special about New Zealand Pepper Plant? 

It’s the foliage!

I love this plant for its visually delicious, red accented colored evergreen foliage. The spruce green leaf is set off by the dark red stems and red lines in the leaf. The new growth stem tips are more of a zippy coral red and when mature, they fade to dark Portland residential landscape designer's favorite coral bell plant, Heuchera 'Blackberry Crisp'burgundy.

Color echo: I find repeating the color of the stems and leaf “trim” with an underplanting in the same hue to be very satisfying. Using a burgundy Heuchera like ‘Blackberry Crisp’ with New Zealand Pepper plant illustrates the idea of a color echo nicely.

Versatile size

It’s very versatile size wise. It can grow into a “shree” (large shrub/small tree 8’ tall), or be maintained as a 3’ tall shrub. It’s easy to prune if you understand the basics and while I strongly suggest hand clipping, if you’ve grown it into a large shrub, it can be sheared with a small power trimmer.  The blades need to be small and sharp since you don’t want to chew up your plant leaves.  Don’t cut back into the old wood.  Typically it will have to grow some new foliage before it looks beautiful again.

While the landscape is where Drimys shines the best, it is excellent for flower arrangements anytime of the year but especially useful in winter when choices are limited. It smells aromatic and the leaves and berries were used in the colonial days of Australia as a flavoring but apparently has a carcinogen in the oil of the leaf.  While small amounts are probably not harmful………………I would skip adding this to your salad. 

Best practices

Plant in raised or well-drained soil out of the range of lawn sprinkler heads. Water once a week deeply with a drip system or soaker hoses.  I’ve placed it in full sun but it works well with some direct sun or lots of lightly dappled shade (under the edges of a tree’s canopy).  It is not a shade or deep shade plant.    

Good drainage is a must. It will die if planted in a low spot or in heavy mucky clay soil.

In Portland’s east counties in particular, the cold east wind may desiccate the foliage.  If I’m concerned about cold winter wind I will place it on the west side of the house in well-drained soil.   I have it growing quite happily in landscape designs in NE Portland, close in SE Portland and Beaverton.

Drought Tolerant Landscaping with Manzanita Plants in Portland

Drought Tolerant Landscaping with Manzanita Plants in Portland

Why am I excited about using Manzanita in my Portland landscape designs?

It’s the water

To advocate the use of Manzanita is to advocate the use of drought tolerant plants. Happily we landscape designers are encountering more clients these days who want a low water landscape or want a completely drought tolerant yard. I can advise about the site conditions drought tolerant plants require and select attractive plants that meet the curb appeal test in addition to drought tolerance.   

Unique look

It’s a new look for the landscape. My younger clients are done with  rhododendrons and azaleas, which are somewhat over used here. While Manzanita has attractive flowers, it is the whole package, foliage color, shape of plant, bark color and flower that is creating the popularity. I’m especially happy with the boost these plants give to the winter landscape. 

Fusion of modern style with NW Natural  

These plants are too naturalistic for formal landscapes but they look great with modern and craftsmen homes.  Style-wise Manzanita fit nicely with NW natural,  Mediterranean or even a southwestern look.  We get strong foliage contrast with  leaf blades (Yucca or ornamental grass), tiny needles like dwarf conifer,  heather (calluna type), lavender or fat leafed succulents like hens and chicks or sedum palmeri or other sedums.

New kinds of Manzanita to use in landscapes 

Drought tolerant Manzanita in Irvington garden design as foundation plant

The fact that we now have more than one kind of Manzanita we can use can be laid at the feet of a handful of people who have crossed different kinds of Manzinita to produce plants that can thrive in our rich Willamette Valley soils.  They then tested the plant in different soil conditions and identified the plants that can handle life in an non irrigated garden or landscape.

When I started my Portland landscape design practice in the 1990’s there was a native Manzanita tree from the Oregon coast that “sometimes” survived here. They are so beautiful that I was tempted.  Still “sometimes” was not good enough for my designs.  I needed cold hardy Manzanita ground covers, shrubs, and small trees that would thrive here in the Willamette Valley and there weren’t any. Now I have them!!! 

Less weeding 

This benefit could take some time to realize.  Manzanita leaves contain a substance that discourages weeds. Leaves that shed from the plant should be left in place. It takes several years for these small leaves to build up enough of the substance in your soil to be effective. 

Pruning tip

Arctostaphylos drought tolerant landscape design planting in SE PortlandOne of the common mistakes with Manzanita is to underestimate the width of the shrubs and small trees. Most cannot be pruned heavily and can be rendered so unattractive by pruning that tries to contain them, they will be removed. If you have no pruning skills (and most people don’t) be sure to place these plants where they have room to mature with yearly tip pruning only.

Fun in the sun: Keeping your yard safe for kids and pets

Checking for Landscape Safety Hazards

Checking your Residential Landscape Design for Hazards in Portland.

Your kids spend the cold and wet Portland winter months cooped up inside, looking for things to do and ways to burn off a whole lot of pent-up energy. When the weather finally warms up in the spring, it’s a mad rush for bicycles, balls and frisbees. Children know only that it’s finally warm enough to play outside; they’re not thinking about potential yard hazards from winter. If you haven’t examined your home’s exterior carefully, your kids, their friends and your pets may be at risk for a mishap that could turn a long-awaited romp in the yard into a trip to the local ER. While most trips turn into a great story for the kids to tell their pals, it’s hair raising while it is happening.

Checking for safety hazards

You wouldn’t turn your kids loose in your basement or a rumpus room you hadn’t checked for safety hazards. You should approach your yard the same way because children and the family dog are going to spend a lot of time out there.

Trees and shrubs

Clearing away yard debris  (fallen branches and sharp twigs) from winter storms, is easy to think of but looking up into your trees to ensure there are no broken but still hanging branches is a less obvious task.  Loose branches are a danger to children playing under or near a tree and should be cut down and removed. It’s hard to see these loose branches once the trees are fully leafed.  Also, check the ground around trees for unexplained disturbed soil, or excessive limb-drop.  Either of these are a sign to call an ISA certified arborist to check on the health of your trees.

ShrubsIce on Joe Pye Weed in Portland landscape. and small trees can encroach into path and patio areas. Check that branches are not protruding into paths especially at eye level of small children and adults.  While not all shrubs can be pruned in late winter and early spring, a single branch or two can and should be removed even when you are not sure about the proper timing for pruning.

Fall Landscape Hazards

Lichen and moss build up on walkways, patios and decks which makes the area super slick and slimy.  They must be scrubbed, or pressure washed multiple times in winter and spring especially on the north side of the house or in shady areas.  Be sure your lighting for your entry walk is functional especially if you live on a street with no street lights.  The lighting needs to extend to the area where your guests park.

Dog friendly landscape designer PortlandExamine the equipment

Your swing set and other play equipment look especially inviting to eager children throughout the winter. Take a few minutes to check it thoroughly before the kids swarm all over it. Make certain that there are no sharp points or edges, or exposed and rusty nails or screws that could cause a dangerous cut. Chains should be secure, and any stakes or stabilizing devices that keep the frame anchored to the ground should be tightly fastened to the ground.

If your swing set is made of wood, keep it stained and sealed to minimize fragments and prevent weather damage. If you didn’t store away detachable components, such as vinyl connecting parts, make sure they haven’t worn down to the point of breaking. Remember that all play equipment should be surrounded by sand, mulch or soft synthetic material to guard against injury.

Patios and wooden decks

Ice, rain and wind can do a lot of residual damage to a deck during the winter. Wooden planks and railings produce fragments and splinters, a danger to kids and pets. That’s why wooden decks should be stained and sealed at least every two years and they will last longer too. The heavy winter rains can wash away soil and undermine paths, patios and walls or re direct water to your foundation.  Sometimes these changes happen slowly over a few years, but spring is a great time to assess water issues on your property.

Diligence and maintenance

If there’s one place your children and pets should be safe from harm, it’s their own backyard. Keeping them safe as they play and roam outside is a relatively simple task – it just requires diligence and routine cleaning and maintenance. Doing a thorough check of your property in spring is a great time to do this.  It’s well worth it to see your little ones enjoying themselves outdoors after a long winter.
