Marsh Bellflower

Marsh bellflower is a
rhizomatous perennial herb with slender,
reclining, leafy, slightly scabrous stems 15-50
cm long that branch above the middle. Leaves
are alternate, linear to linear-oblanceolate, 1-
4.5 cm long x 1-5 mm wide and become
increasingly smaller higher up the stem. Leaf
margins are entire to finely serrate. Flowers
occur singly on slender stalks. Calyx lobes
are less than 3 mm long. The bell-shaped
corolla is pale blue to white, 3-8 mm long,
and 5 lobed. Fruits are capsules 2-3 mm long.
