Portland Landscape Designer Appreciates Diversity of Dogwood Trees

We recommend this 30′ wide tree for back yard or front yards not parking strips but here it is doing well in a parking strip in Overlook neighborhood of North Portland.

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

Colorful Summer Privacy Tree for Small Properties – 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.  The foliage will be a delight from spring into fall and this tree is a narrow vase shape perfect to put between your patio and the neighbors to achieve attractive  privacy.

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”.

Elegant Branch Structure Cornus Controversa ‘June Snow’ Perfect Light Shade Tree

The flowers of ‘June Snow’ giant dogwood float above the graceful branches in Overlook neighborhood.

‘June Snow’ can be the single tree in your  small city 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 and for a shade tree she is typically limbed up so it is easy to walk and play under this tree.

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 white flowers which are 6 to 7 inches across.

Spring Flowers

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.

Bright Summer Foliage

‘Hedgerows Gold’ grown for its gorgeous variegated foliage. This is a very easy shrub to grow, once it is established it can take some benign neglect. Grow it for the foliage first, but the fun fall color and exciting winter twigs makes it a four season plant.

Fall Color

Yellow Fall Color on this Dogwood looks especially bright with the evergreen background.

Many Dogwoods also sport great fall color. The fall color is primarily in sunset shades, reds and yellows, and looks especially fantastic with an evergreen backdrop. On some varieties the color of the leaves turning is only enhanced by the unique twig colors – clear yellow leaves with bright red stems. Beautiful!

Winter Twigs

Some types of dogwoods are known primarily for their winter twig color – most often called Red Twig Dogwoods or Yellow Twig Dogwoods. ‘Midwinter Fire’ is a popular cultivar, but there are a wide variety to choose from.
