Penstemon is a large genus of perennial herbs from
North America and East Asia. They have opposite leaves, partly
tube-shaped, and two-lipped flowers and seed capsules. The most
distinctive feature of the genus is the prominent staminode, an
infertile stamen. The staminode takes a variety of forms in the
different species; while typically a long straight filament extending
to the mouth of the corolla, some are longer and extremely hairy,
giving the general appearance of an open mouth with a fuzzy tongue
protruding and inspiring the common name beard-tongue. The Ice Cream
Series includes 11 exciting and colorful garden cultivars, all with
unique, large, bell-shaped, bicolor flowers and strong, upright stems.
These upright perennials have oblong to ovate, lance shaped, blue-green
leaves. They grow up to 1.5 ft tall and spread to a foot in diameter.
Different varieties in the Ice Cream series are Blueberry Fudge,
Brambleberry, Bubble Gum, Juicy Grape, Melting Candy, Raspberry
Pavlova, Raspberry Ripple, Strawberry Cream, Sweet Cherry, Vanilla Plum
and Vanila. You are likely to find them in the hill stations of India
in summers.
