General Description

This stunning purple foliage variety is rewriting the book on what to expect from perennials in the garden. It is a cultivar developed by Terra Nova Nurseries in Oregon where some of the most innovatively colored new cultivars are being produced. Penstemon foliage has previously been of minimal interest, but with the dark purple leaf form it makes these plants far more valuable before and after blooms.

Bright pink midsummer flowers are abundant but not particularly large. This is of little concern because they stand out in such high contrast to stems and foliage that they are truly dynamic. For those in the South, this presents a more useful hybrid due to its improved tolerance for humidity and high heat. Combine this to marked cold tolerance and you have a perfect candidate for much of the North as well. The best quality of these new penstemons is less tendency toward root rot in ordinary soils, but they still prefer adequate drainage and a short dry period between watering or rainfall. This plant requires a distinct winter chilling to bloom and grow reliably and may not perform as expected in very mild climates.
