Our native Giant Chain Fern that occupies specific spots in seeps randomly from CA to BC. Large pendant and trailing 3′ long glossy fronds form huge rosettes. Usually occupying permanently wet seeps on shady hillsides in cool places. The entire plant may be up to 5′ across. Evergreen but it benefits greatly from some early spring tidying of spent and aging old leaves. Part shade to shade in rich well drained soil with regular consistent moisture for the best look. Highly deer resistant. We’re honored to grow this, one of our most spectacular native ferns. Oregon native plant.
A mesic biome is one that enjoys a fairly constant supply of moisture. Some natural examples include riparian areas or streamsides, the edges of lakes or ponds, and springs and seeps. Irrigation, of course, can turn an otherwise summer-dry area into an effectively mesic biome. A true mesic plant does not handle drought stress at all, instead of wilting they often go straight to crispy. Simply lacking the mechanisms that conserve moisture for xeric plants. Liberal mulch and deep, rich, moisture retentive soil amended with compost all combine to make life easier for the gardener as well as plants. Group water loving mesic plants together to more efficiently irrigate. You’ll save time and water.
Climate Adapted Plants for Gardeners in the PNW
Relatively new fern with a great future ahead. Large growing evergreen chain fern from Asia with new growth lavishly dyed red- it settles to soft green with time. To 3′ across the fronds are held atop relatively long stems. The rubbery green leaves are finely divided with surprisingly soft lobes. Rich, moisture retentive soil in bright shade to shade. Spectacular plant at all times we have observed it. So far it has not suffered damage in my garden below 10ºF and appearance following a rough winter was good. Highly deer resistant. Spectacular.
Calla Lily- the dream of many gardeners and an heirloom perennial that has been grown in our region for eons. Large clump forming perennial with dramatic pure white flowers with the familiar form. They begin in early spring with a large flush of bloom and then sporadically until frost. The large boisterous foliage is mostly evergreen and rises to 2′ tall with flower spikes twice as tall. Deer resistant. In cold gardens it is traditionally grown agains warm foundations. But I have seen it thrive in the wide open in the coldest parts of the Willamette Valley. Amenable to saturated soils and can reside as a marginal plant in a pond. Rich, well drained soil is ideal. Water VERY heavily the first summer to establish- then light consistent water in summer. Full sun to quite a bit of shade but at the expense of flowering. Can be a little tricky to establish and ironically it can be a little hard to get rid of once you have it. Lives for many decades.
