Just because its winter (don't let the 60 degree weather fool you) does not mean your landscape has to be boring.
There are lots of plants that add winter interest to an outdoor space
from ornamental grasses to evergreen trees.
Even the seed heads of some herbaceous perennial plants can look
attractive in the winter. One group of
plants which shines in during the winter due to the variety of feature and
types of interest they can create during the season is shrubs.
Some shrubs have twigs which are an attractive color or
provide and interest texture to a landscape. For example, red twig dogwood (also known as
redosier dogwood- Cornus sericea)
has showy twigs that bring color to a winter landscape.

Harry Lauder’s Walking Stick (Corylus avellana 'Contorta') as well as several species of Willows
(Salix sp.) have contorted habits
which add texture to a landscape.

Other shrubs retain their fruit into the winter which can
add interest and color to a winter landscape as well as attracting birds. Many
species of hawthorn (Cratagus sp.) retain
their fruit into the winter along with shrubs like firethorn and some
crabapples.
Due to their spreading suckering growth habits some sumacs (Rhus sp.) should be used with care in
smaller landscapes. However, many
species of sumac keep their interesting red fruits through winter.

Most people are familiar with the more common evergreens
like pines, spruces and junipers.
However many are less familiar with broad leafed evergreens. These plants retain their leaves all winter
and add both color and texture to a winter landscape. There are actually quite a few broadleaf
evergreens which can be grown in our area including, curl leaf mountain mahogany, mountain mahogany,
winter creeper euonymus, Manhattan euonymus, English ivy, Oregon grape holly,
creeping grape holly, manzanita, joint fir, Spanish broom and firethorn. All of these plants will benefit from winter
watering and many will do better in sites which are protected from drying
winter winds.
Derr has staghorn sumac as Rhus typhina. Rhus trilobata is the three-leaved sumac.
ReplyDeleteThanks for catching that. It must have been a freudian slip as I'm much more found of R.trilobata and R.aromatica (and their cultivars) than R.typhina. Staghorn sumac's fruit is just much more showy.
ReplyDeletewinter creeper and english ivy can be pretty invasive
ReplyDeleteThis is a really good point. In other parts of the country (the Northwest and Southeast and maybe other regions) English ivy and winter creeper are indeed considered invasive weeds. However, along Colorado's Front Range I would say they can be "aggressive" rather than "invasive". They are not plants for small spaces and under the right conditions can definitely take over a space.
ReplyDeleteHowever, at least in my experience, they are not particularly "invasive" in that they are coming up form seed (more than occasionally) in other parts of that garden or natural areas. Actually, English ivy often struggles in our climate if its not planted in a site with the proper microclimate.
