Yellow Foxglove (also known as Digitalis ambigua) is the longest-lived perennial in this popular genus. The soft yellow flowers appear in June and July and continue into fall. This shade blends with both hot colors and cool.

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.
