Round-Leaved Sundew


 Round-Leaved Sundew—Drosera rotundifolia is a very odd, distinguished small, 5-25 cm tall plant. Drosera came from droseros in Greek which means "dewy, watery." Leaves are very sticky and glandular, and blade round egg-shaped. They have long reddish glandular hairs that exude drops of sticky fluid. Flowers are small and white and fully open only in strong sunlight. They bloom in summer and early fall. They prefer sphagnum bogs, wet meadows at low to middle elevation, swamps, mossy crevices in rocks, damp sand along stream, lake, or pond margins. They may also grow on other moss or sedge peat soils. They were seen through the Pacific Northwest Coast. Rund-Leaves Sundew is very shade intolerant since it’s small, even sedges, grasses, and small shrubs may limit light. Insects are caught with the sticky glandular leaf hairs. The hairs digest the insects and enable the plant to absorb nutrients through its leaves. Insect capture is generally believed to enhance growth and reproduction. It’s known as “many hearts” in Haida and used as a lucky charm for fishing.
