Bottle gentian

Description:

his native perennial plant is 1-2' tall. Multiple stems can emerge from the taproot, otherwise this plant is unbranched. The central stem is round, hairless, and either light green or purple. The opposite leaves are up to 4½" long and 2" across, and sessile against the stem. They are broadly lanceolate or ovate, with smooth margins and parallel venation. The upper surface of each leaf is dark green and often shiny, while both the upper and lower surfaces are devoid of hairs. The uppermost tier of leaves is often whorled. The apex of the stem terminates in a cluster of flowers immediately above the whorled leaves, while smaller clusters of flowers may develop from the axils of the upper pairs of leaves. These flowers are bottle-shaped, looking like oversized flowerbuds even when mature, and they are 1–1½" long.

Habitat:

Sandy woods

Notes:
