Deadly dew
The plant Darwin cared about more than the origin of species
Charles Darwin was obsessed with sundews. In 1860 he wrote to a friend that he cared more about Drosera "than the origin of all the species in the world." He spent years testing them and found a leaf could feel a speck of hair far too light for us to notice, yet only curled up properly around real food, not sand or glass. Every leaf is covered in fine tentacles, each tipped with a bead of sticky dew that looks like nectar. Anything that lands is held fast as the tentacles slowly fold in and the leaf curls around it.

Growing Sundews (Drosera)
Read the full care guide →Light
Strong, direct light: 4 to 6 hours of direct sun, a grow light on a 12 to 14 hour cycle, or both. Strong light means healthy, heavy dew.
Water
Rainwater, distilled or RO water. Stand the pot in a tray of water, a couple of centimetres deep or up to about 1/4 of the way up the pot, and top it up as it evaporates.
Dormancy
None needed for our subtropical sundews, which grow year round. D. dichotoma is the exception, and needs a true cold winter rest.
