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

Residential Garden Design Portland, Oregon Woodstock neighborhood.Less successful is the privacy screen planting for the side yard.  I used a narrow variety of Hornbeam (Carpinus betulus ‘Franz Fontaine’) to block the view of the neighbor’s driveway and their vehicles and also to create an attractive view from the bedroom Affordable Landscaping Portland residential trees.windows. 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.

Diversity of Dogwoods Part II

Portland Landscape Designer Appreciates Diversity of Dogwood Trees

The diversity of dogwoods is well illustrated by these two trees:  Cornus Kousa ‘Summer Gold’ and Cornus Controversa ‘June Snow’.

Korean Dogwood ‘Summer Gold’

I love ‘Summer Gold’ partially because it’s so different from other dogwoods.   ‘Summer Gold’ has narrow bright green and gold leaves and an upright narrow shape.  The shape fits into urban settings much better than a round headed typical dogwood.

Traditional dogwoods (Cornus Florida and Cornus Kousa) have a wide oval solid green leaf and a  20′ or more wide round canopy.   ‘Summer Gold’ was created by local Crispin Silva who is a delight.  His curiosity and enthusiasm about plants has inspired many people in Portland including me. People here refer to his plants as “Crispin’s Creations”.

‘June Snow’ can be the single tree in your backyard because she has it all, grace, fall color, and an amazing floral display.

‘June Snow’ Dogwood matures at 30′ tall and spreads to 40′ wide. She has an arching shape and while bigger than typical dogwoods She has the most graceful silhouette even in winter.  I use her to create light shade for medium to medium small landscapes.  Too big for your typical row house back yard that is only 20′ wide, with another ten feet she can be the single beloved tree.  She was introduced by J. Frank Schmidt Company also near Portland, Oregon.

Her branch structure is incredibly graceful and open.

Cornus 'June Snow'

When she flowers in June these flat topped clusters (which often exceed 6 inches) seem to float above the foliage.  The fall color on ‘June Snow’ can compete with any dogwood. The color show starts with orange yellows and moves into intense purple red and purple as fall deepens.  The fruit that develops from the flower clusters are quite tiny and not messy.  The local birds will eat them.

Studying trees is what Portland landscape designers do so we can bring you the best choices.  Ok and we are geeky about plants.   Read more about dogwood trees….. Diversity of Dogwoods Part 1

Diversity of Dogwoods – Part I

Dogwoods are a very large family.  There are twiggy shrub dogwoods whose hot colored stems light up the winter landscape.  There is a dogwood who blooms in March with yellow flowers and makes an edible fruit.  There are semi evergreen dogwoods we are experimenting with here in Portland.  This is the kind of knowledge homeowners need their designers to be up to date on.  When a client asks me for a dogwood I know its the visual and emotional impact of the flowers they are thinking of.  Designers think through the details to find the right variety for the clients size of yard and environment so our clients don’t have to.  Landscapes come in all different sizes and environments and now so do Dogwoods.

Plant designers have been busy improving our old-fashioned dogwood tree into a garden designers dream tree. Our old dogwood varieties have problems that plant designers have been working on for 40 years.

They are improving drought tolerance, disease resistance (okay not sexy but important!)  and cold hardiness.  They’ve created new shapes that fit better into the urban environment.

What is sexy or desirable are the improvements made to the flowers.  Let’s admit it, where dogwoods are concerned,  we want even pinker flowers.   Everyone wants more color than nature supplies on her own. There are darker shades of more intense pink red.

Cornus Kousa 'Venus' has large dogwood flowers

Cornus Kousa ‘Venus’ has large white flowers which are 6 to 7 inches across.

Varieties such as ‘Little Ruby’  showcase the new strong colors.   ‘Little Ruby’ is wider than tall.  She is  plump and round headed and can be used in the landscape as a shrub or small tree.

Another new variety is called ‘Starlight’.  This cross is from our own native Pacific Northwest Dogwood;  the shape is upright and more narrow.  It works for your small yard or as a street tree. There’s a beautiful ‘Starlight’ in the courtyard of the Edith Green federal building in downtown Portland as an example of a tree perfect for urban life.

‘Venus’ features ginormus white flowers which are 6″-7″ across.  Like ‘Starlight’ they produce little to no  fruit unlike the many Korean dogwoods hybridized and sold in the last 15 years.  In fact even Friends of Trees offer messy Korean dogwoods.  I confess I make a TSKK TSKK when I see the huge mess they make on the sidewalks. In the fall they drop a large raspberry colored fruit.  Friends of Trees is a fabulous organization and many clients have been happy to purchase an inexpensive tree and learn how to care for their tree.  I would use the fruitless varieties near walkways and for small yards and save the old fashioned fruiting types for large properties.
