Description

Drosera rotundifolia, commonly known as the round-leaved sundew, is an insectivorous plant species belonging to the sundew genus. It is a temperate species native to Europe, Canada, and either the east or west coast of the United States.

Drosera rotundifolia is a perennial herb which forms a semi-erect rosette with short stems of spatulate leaves up to 10 cm tall. Plants in temperate regions undergo dormancy during which they form a winter resting bud called a hibernaculum.

As is typical for sundews, the leaf blades are densely covered with stalked mucilagenous glands which secrete a sugary nectar to attract insects. These then become ensnared by the mucilage and, unless they are strong enough to escape, are suffocated or die from exhaustion. The plant then secretes digestive enzymes from sessile glands and later absorbs the resulting nutrient solution to supplement the poor mineral nutrition of the plants natural environment.

Drosera rotundifolia typically blooms from June through August, forming up to 15 cm. tall inflorescences bearing 3-8 white flowers. Fertilized ovaries swell to form egg-shaped dehiscent seed capsules which bear numerous small seeds.

Drosera rotundifolia is one of the most widely distributed species in the genus, and one of only three Drosera species native to Europe (the others are D. intermedia and D. anglica). 

Drosera rotundifolia grows in sunny, but constantly moist habitats including bogs, fens, wet sandy shorelines and wet meadows. Since it is carnivorous, it is able to occupy relatively infertile habitats including wet sand and peat.

Note: These seeds are fairly small! It's just how they naturally are. Reading glasses are recommended to aid with seeing them, even for those who don't normally require glasses to read. The seeds are shipped in either a wax envelope, or folder within a small paper. Open carefully, and sprinkle onto the growing medium. Do not bury the seeds. Germination information is below.

Type: Hardy perennial

Hardiness zones: 5-9

Seed origin: USA

Germination: Start these seeds right away for best germination rates. Fill the container with a mix of peat and perlite at a 1:1 ratio. Place the seeds on the surface of the pre-dampened mix, and gently water with a spray bottle. Cover with clear plastic, and place your container in a cool area (but not freezing) for 6 weeks. Once the cold period is completed, place the container at room temperature, and in bright light for them to germinate. Be sure to keep the soil moist during this entire germination period. Most seedlings will sprout within 2-3 months of the warming period, though some may take a little longer. Once plants sprout, slowly remove the plastic, a little bit each day. Always keep the soil slightly moist, never letting it dry out.
