Bred in Canada, 'Polka' one hardy Weigela (to -30!).  That's a good thing, because unlike most Weigela, 'Polka' blooms continuously. From early summer to early fall it produces clusters of shell pink trumpet-shaped flowers. This mid-size Weigela can be used as a specimen, a foundation planting, or even a hedge.

Bees, butterflies, and hummingbirds love Weigela, and so do gardeners. For a plant that gives
you so much to look at, they're very easy to care for. No particular
disease or pest problems. No special soil requirements.No deadheading. Just give them
good drainage, reasonable moisture, and plenty of sun. Prune after
spring bloom...fall pruning puts  next year's flowers at risk.
