Beaked Yucca does fantastically well in our climate and is one of the Yucca species that will form a dramatic trunk. Blue thin leaves radiate out in a perfectly round orb. Slowly rises to 8′ tall in our climate. Full hot all day sun in a warm position. Very well drained soil with light summer water during the hottest stretches to encourage growth. Occasionally, with age 4′ spikes appear holding large trusses of ivory flowers. Perfectly hardy to cold, way below 0ºF. Avoid cold wet sites- to really do well it needs heat and exposure. Not prone to bacterial leaf blight that affects other Yucca species. Good air circulation. Lives happily in large containers for eons. Focal point in many of the best gardens in our region. High deer resistance. Evergreen.
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.
