Contains approximately 50 seeds. Drosera burmannii is a great plant for growers who have bright, warm conditions all year. Because of these requirements, they make fantastic additions to well-lit terrariums and sunny windowsills. Drosera burmannii is best known for being one of the fastest-trapping sundews. Their tentacles entrap prey in a matter of seconds, rather than the minutes taken by most other sundews. Drosera burmannii is an annual plant in its native environment, but can be grown as a perennial under the correct conditions. The rosettes of Drosera burmannii can be up to 1.5 inches across, but they are typically much smaller.
