ROUND-LEAVED SUNDEW
Drosera rotundifolia
REMEMBER: It is an offence to pick wildflowers in any provincial park.

Round-leaved Sundew, also known as Dewgrass, Lustwort, Red-rot, or Youthwort, is a perennial found in bogs, swamps, and wet sandy acidic soils. The scientific name “Drosera” means dew, which refers to the dew-like drops liquid on its leaves.

A basal rosette of leaves, growing up to 10 cm wide, are covered with reddish, sticky hairs. The substance entrap insects, triggering the hairs to enfold around the prey. Its enzymes then digest the insect.

Its white flower, with  5 sepals and 5 petals, grows to 4-6 mm long at top a leafless stalk, to a height of up to 20 cm. From June-July you can find them blooming in the Algonquin Highlands, arranged in an elongate, one-sided cluster.

This plant has been used as an aphrodisiac, hence the name Lustwort. It is sometimes used for some medicinal purposes.
