Pitcher Plants

From Wikipedia, the free encyclopedia

Sarracenia alata, also known as the Pale pitcher plant or Pale trumpet, is a carnivorous plant in the genus Sarracenia. Like all the Sarracenia, it is native to the New World and grows in permanently wet and open wetlands typically classified as longleaf pine (Pinus palustris) savannas. The Pale pitcher plant's habitat is split into two geographically separate areas: an eastern range from eastern Louisiana across southern Mississippi and into western Alabama and a western range from eastern Texas into western Louisiana. In Mississippi, stands of Sarracenia alata rival in size those of any other Sarracenia species.

Among members of Sarracenia the floral coloring of Sarracenia alata is remarkably varied. Flowers may be cream to white, greenish, yellow or reddish. As the floral color variations exist within populations hundreds of miles from any other Sarracenia species, these variations cannot be attributed to hybridization.

Other than the range of floral colors, Sarracenia alata differs little from Sarracenia rubra. The veining of Sarracenia rubra pitchers tends to be more reticulated whereas that of Sarracenia alata often exhibits more of a pinstripe pattern and grows taller pitchers.

Sundew

From Lady Bird Johnson Wildflower Center website; www.wildflower.org

Drosera brevifolia
Dwarf sundew, Spatulate-leaved sundew
Droseraceae (Sundew Family)
Synonym(s): Drosera annua (Annual sundew), Drosera leucantha

Sundew is an insectivorous plant with a unique way of catching its prey. The paddle-shaped leaves of the sundew form a rosette at the base, greenish to reddish and densely covered on the upper surface with hairs exuding a clear, sticky liquid which attracts and traps various kinds of insects. There are several flower buds at the end of a single, delicate stem, 4–5 inches tall, and they open one at a time. They have 5 pale pink petals, 3/8 inch long and almost round.

Butterwort

From Lady Bird Johnson Wildflower Center website; www.wildflower.org

Pinguicula pumila
Small butterwort, Bog violet, Dwarf butterwort
Lentibulariaceae (Bladderwort Family)
Synonym(s): Pinguicula pumila var. buswellii

Small butterwort grows 6–8 inches tall above a basal rosette of broad, succulent leaves. The few leaves form arosette at the base of the plant and have a sticky surface that captures small insects. The margin of the leaf rolls inward over the insect until it is digested. There is 1 flower, whitish or pale violet, about 3/4 inch across, funnel-shaped, somewhat 2-lipped, with 5 petal-like lobes and a spur at the base, like a larkspur.

All Pinguicula spp. bear short glandular hairs, and clammy leaves designed to trap small insects.
