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

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.

How A Garden Helps Your Family By Helping Bees

Portland Residential Landscape Designer How A Garden Helps Your Portland Family By Helping Bees

As a parent, you work hard to help your family. That means you have to look out for their welfare. And believe it or not, that includes helping bees.

These insects do a lot for your family, but they are disappearing at an alarming rate. Thankfully, your family can support bees by creating a garden. Not only will this help them thrive, it’s fun for you and your children. But first, you need to understand why a dwindling bee population is a problem.

Bees Are Vital To Your Food Supply

The secret to why bees are so important is one word: cross-pollination. This is when pollen from one plant gets to a new plant. Pollination is what creates seeds to grow a new generation.

This is where bees come in. As they fly from flower to flower, they cross-pollinate plants. National Honey Bee Day tells us that 50%-80% of the food supply depends directly or indirectly on pollination by bees. Some of the crops that depend on bees for new seeds each year are apples, watermelons, coffee, strawberries, and even plants used by cattle as food.

That’s why this is a big problem for your family. Without bees and pollination, many foods your family enjoys will either get very expensive or disappear altogether.

Creating A Bee-Friendly Garden

Lavandula stoeches ‘Winter Bee’

Thankfully, your family can do something to keep those foods on the table. It starts with a garden.

Bees need flowers for food. The more flowers they can find, the healthier they can become. This leads to more bees, helping their numbers get back to where they used to be. That’s why your family can help by creating a garden at home that bees will love.

Beverly Bees has several tips for helping your garden work for this.

  • You can pick flowering herbs (basil, mint, sage), flowering vegetables (broccoli, cucumbers, strawberries), or just flowers.
  • Group the same plants together in the bed to make them more attractive to bees.
  • Pick plants that bloom at different times of the season so bees have a constant food supply.
  • Late winter and early spring plants are harder for most people to plan for.  Here is Carol’s blog about flowers for winter bees.

When you visit your local garden supply store, it might help to know some terms about gardens and landscaping in general. HomeAdvisor.com has a great glossary of these terms so you know what you’re talking about.

Health Benefits Of Gardening

Garden Design Portland Designing a garden will help bees stay healthier, but your family will benefit from it as well. Organic Life explains five surprising ways gardening can help your family’s health:

  1. Reducing stress and anxiety.
  2. Decreasing risks of heart disease and diabetes.
  3. It improves happiness.
  4. It cuts the risk of Alzheimer’s by half.
  5. It improves sleep.

Gardening can also improve everyone’s self-esteem. This activity reduces cortisol in the body, which helps you feel better about yourself. In fact, just seeing your garden growing can help people feel like they did something helpful.

A Garden For Bees And Your Family

If too many bees disappear, a lot of food your family enjoys will get more expensive or even vanish. That’s why building a garden to feed bees can help. Plus, just making a garden can do wonderful things for your family. Who’s ready to get dirty? Make an appointment to start designing your Portland garden.

Trees for Portland Residential Landscape Design in Woodstock neighborhood

One September afternoon while in Portland’s Woodstock neighborhood I  drove by a former client’s home. My clients had moved, and I was curious to see how the design (installed a dozen years ago) had held up. Once clients move I rarely have continuance with the landscape.  

This drive by is a mixed bag.

Shade Tree for the backyard

Affordable Landscaping Portland design in residential Woodstock.

The shade tree for the back yard is absolutely perfect, and exactly what I had envisioned. This is the part of drive bys I like the best. I used a Japanese Elm – Zelkova serrata variety called ‘Wireless’ because it’s one of the few shade trees that is compatible with lawn and ‘Wireless’ is the perfect shape and size to provide shade for city landscapes.

Their leaves are smaller than most shade trees and allow dapples of sunlight through the canopy to the lawn while filtering out the heat. The exaggerated vase shape of the tree also allows light to come in under the tree in the morning and late afternoon.  This tree provides shade to the south facing deck and the back of the house. It will get over 30’ wide at the top. It matures at 25’ tall so it is a tree that will be wider than it is tall.

If you are a discerning shade aficionado you will say hmmm…… the shade tree doesn’t have low branches so how can you sit on the back deck and have dinner without being blinded by the south sun? We kept a mature mixed hedge at the back of the property and it will block those dinner hour sun rays. The shade tree will filter the hottest sun of the day.

Privacy Screen Planting for side yard

For the design to be functional, the Hornbeam would need to be pruned once or twice a year to become a 10’ narrow wall of thick leaves. The maintenance did not happen since my clients moved.  Now the side yard privacy screen is wildly out of scale and the charm is gone.

Success with Crape Myrtle in Portland Landscape Designs

Residential Landscape Design PortlandLandscaping with Crape Myrtle in Portland

I responded to a request for help from clients in Northeast Portland who were concerned their crape myrtle trees planted two years ago were not healthy because they didn’t flower. They had done their research on crape myrtle but unfortunately not from a source familiar with their trees cultural needs or growth patterns here in the Willamette Valley.

Let me knock a few myths out of the way to save you the same unease and help get our crape myrtle trees off to a good start.

  1. Crape myrtle are drought tolerant so don’t ever water them. Not so!

Latest wisdom is to water them deeply with a drip irrigation or soaker hose once every 10 days. Touch the soil with your hands down a few inches to ensure you are not over watering. It should be moist and then as you get closer to the time to water again it should be almost dry. This may change some once they have been growing for ten years in your landscape, at that time you might be able to experiment with occasional deep slow and long watering.   Then they might become  low water needs.

I like to design plant companions for the crape myrtle that have the same water needs. In this garden I have crape

myrtle with Chinese Camellia – Camellia sasanqua ‘Yuletide’ and American Switch grass-Panicum virgatum ‘Shenendoah’. The clients added ground cover sedum.    None of the plants near the tree need to be watered more than once a week ever after except perhaps for their first summer. A splash of hose water once a week is not at all what I am talking about, I am talking about slowly applied water and preferably drip system or soaker hose.

  1. Fertilize if you want a lot of flowers, that’s true for all plants, right? Not so!

First off, nothing is true for all plants. There are plenty of plants that are harmed by fertilizer so tuck that behind your ear for a future conversation. We typically have fertile soil here in the Willamette Valley, so I would never fertilize crape myrtle beyond adding garden compost to the soil once a year as a top dressing. Adding fertilizer will work against your goal of having flowers.A young crape myrtle in SE Portland landscaping.

  1. You must dead head (pinch off) all the spent flowers. No way!!

If I had to deadhead crape myrtle flowers, it would take a bazillion hours and eventually a ladder.  Nope, you don’t need to deadhead. When your tree is young, and you get a heavy crop of flowers you might want to thin out some flowers to prevent the young branches from breaking.

  1.  Flower timing will depend on our summer temperatures. True.

It’s got to be hot enough and stay warm even at night to kick off the flowering of crape myrtle here in the Willamette Valley. If we have a cool June which we do sometimes, the flowers will be delayed until it’s been warm enough for long enough. For a deeper dig into crape myrtle read my comments published in this in-depth article from The Digger, July 2020.

Sleep-Creep-Leap

These clients came from California, a climate where plants grow fast. They were not familiar with the saying “Sleep-Creep-Leap” which describes typical plant growth for the first three years.

Just to be perverse, some plants grow slowly when young and then after they are a decade old, they grow much faster. It depends on the genetic makeup of each plant as to its growth rate.  Generally, it takes 3 years of root growth in a plant to get to leap.

Patience in our culture is a revolutionary idea. Contact me if you have more questions on your landscaping.
