Hebe
Portlanders have a love-hate relationship with Hebes. We are lured in by flashy evergreen leaves and pretty summer flowers, we think they're wonderful when our winters are mild - then we get the occasional cold snap and (some of them) die. We're sad and angry and we vow never to plant another Hebe...then we fall in love again.
Plant care & info
Family: Scrophulariaceae (figwort or foxglove family)
Genus: Hebe
Origin: New Zealand
Full sun.
Requires excellent drainage. Drainage in the soil can’t be overstated. Hebes are far more likely to suffer in our heavy clay soils, especially in waterlogged winters.
Hebes aren’t particularly drought tolerant. Many Hebes are damaged in winter when temps drop below freezing and there is no precipitation. Dry soil and dry air is very hard on evergreen plants, so make sure to water, even in winter.
Prune after bloom by cutting back branches that bloomed by half to maintain compact form, as they bloom on new growth. Also a good thinning every couple years keeps Hebe in good shape. They can be rejuvenated by cutting back severely, as they will sprout from old, leafless wood as long as not all the green growth is removed.
The thing is that some Hebes are perfectly hardy in Portland. The key is to know which ones are reliable and which ones are not, so if you choose to take a chance on a more tender Hebe, you do it with open eyes, knowing it may end in tears, but ready to enjoy the time you have together.
Generally speaking, the smaller the leaf, the hardier the Hebe; the more impressive the flowers, the more tender. These are no a hard and fast rules, so always read labels.
Hardy Hebes
We feature Hebes that are hardy in USDA Zone 7 to be reliably hardy in Portland.
Tender Hebes
Portland’s USDA hardiness zone is Zone 8B, which means that temps don’t usually go below 15F (of course we know it does get colder sometimes, but not often). Many of our winters are warmer, and in those years, tender Hebes typically survive and even look great while doing it! For best success, plant tender Hebes in spring or early summer so they can get established well before threatening cold, make sure to keep them watered during dry spells in winter (and summer too), and cross your fingers for a warm winter.
Because they’re so temperamental, we focus on tender Hebes that have exquisite foliage or flowers.
