As we move into the winter season and the options for flowers significantly decreases we turn to foliage for our color fix and surprisingly we have many choices. By far the biggest group of plants to offer us winter color is our evergreens which botanically speaking are called conifers. (There are also broadleaf evergreens like holly and rhodies that can provide us with winter interest but that subject is for another column.)
Winter is when conifers come to the center stage of the garden. During the season there are way too many distractions to even notice them. But once all the flowers are gone and the foliage has frozen away the conifers become the dominate elements of the landscape. They become the framework of our borders and beds and help us to remember how the spaces are articulated in our gardens. They are also good candidates for containers.
When I first moved to the northwest I was overwhelmed with the choices of conifers. Having been a landscape contractor in northern California where it was
hotter than you know what we had two options for conifers, pines and junipers, not much to get excited about. But here in the northwest we can add at least 10 more genera and a plethora of varieties and cultivars. Over the last 25 years I have come to love many flavors of conifers but if you really want to learn to speak “Coniferese” then you need to attend our class this coming Saturday at 10am where Trevor Cameron will share his unabridged knowledge and passion for this versatile group of plants.
Far too many northwesterners have the annoying habit of referring to all evergreens as “pines.” I am not sure how this came to be considering that our native forests are dominated not with pines but rather cedars, firs, spruce and hemlocks. On the east side the pine tree is the dominate conifer but not the case on the west. Because we are part of the Pacific Rim many Asian species of conifers thrive in our climate and have been introduced over the years. Had it not been for the Ice Age and Continental Shift I suppose many might still be considered native to our area.
This is by far the best time of the year to shop for conifers. Many of them have taken on winter colors of plum and bronze instead of their summertime blue and green. There are even a couple of pines that turn a bright yellow in the winter. Conifers will be the predominate feature in the garden center, usually moved into a prominent location where they can’t be missed or lost in a morass of annuals and perennials. You might be surprised at the contrast and drama you can generate with conifers just from the variety of foliage colors and growth habits that are available. And don’t forget to look for miniature varieties that only grow an inch or less a year which makes them well suited for containers, rockeries or miniature gardens.
Conifers generally are relatively undemanding. They love our acidic soils and ample rainfall, just make sure they have good drainage. Some conifers can be pruned or sheared into hedges or topiary shapes while others need to be allowed to grow naturally. In the end, there is a conifer for practically every application you could ever think of from full sun to full shade and drought to dampness. Come to our class this Saturday and find out for yourself.
