Drosera rotundifolia or Round-leaved Sundew is aptly named. Its round traps are lime green with long red sticky tentacles. It is of medium height, and prefers growing in and among sphagnum moss, where it keeps up with the fast growth of the moss. It does well growing with other bog plants, where it receives mottled sunlight. It does not tolerate temperatures over 85°F very well. It emerges late in the Spring and lasts throughout the Fall. It forms a hairless winter hibernacula (resting bud), which is best pushed down to the surface in early Spring for best growth. The small flowers are white with occasional pink veins on scapes with multiple blossoms. It flowers from June to September. It frequently produce abundant seeds, giving it a nice spreading habitat. Seeds need to be stratified (cold, damp winter storage). It is wide-spread in its range through North America and Europe. Drosera rotundifolia is probably the most studied of all the Drosera. Charles Darwin experimented more with the carnivorous habit of this plant than with Dionaea. It is a nice plant for a terrarium, the collection or growing in the bog garden. This selection comes from seed, and will show some natural variations. For maximum effect use multiple plants in a 6" pot.
Height: 1" - 2".
Plant Type: Perennial, cold temperate.
Soil: Lower Bog Mix or General CP Mix or Live Sphagnum Moss.
Light: Bright indoors, full sun to partial sun outdoors.
Use: Grows well in the soggy bog garden, greenhouse and indoors. It is a good plant for terrariums, but must be provided dormancy.
