The flowers of Excelsior hybrids fully surround the stem with rich shades of pink to lavender pink, light pink, and pure white. This biennial form blooms in June and July and reseeds itself.
The genus Digitalis comes from southern Europe and has some 20 species, mostly perennials. They grow either in sun or partial shade, which makes them ideal plants for woodland gardens. Some are biennial, and even the perennial forms tend to be short-lived, but their extravagant flowering more than compensates for this, and many will reseed themselves. Foxgloves are of easy culture and make excellent cut flowers if picked when the blooms are half open. But their real strength is as dramatic and richly colored vertical accents, a look that is impossible to duplicate with another genus.
