Plant dimensions: The slender leaves of Drosera affinis can reach nearly 4 inches across at maturity. Drosera affinis forms a slender stem over time. The Namibia form has long petioles and compact oval-shaped leaves.
Temperature: not picky. Has grown well for me in the temp range of 55-95 degrees F. Give Drosera affinis subtropical conditions for the fastest growth rate.
Lighting/Photoperiod: I grow mine under T-8 lights with a 16-hour photoperiod (within 2-5 inches of the lights. The leaves will turn a brilliant orange-red color under intense- enough lighting.
Dormancy requirements: None required. Can be grown year-round if grown indoors during the cold months. However, Drosera affinis should come back from the roots if it freezes or dries out briefly.
Flowers and seed production: D. affinis produces a slender flower stalk. It self-pollinates on its own, but you can assist self-pollination for better seed-set. Avoid hot temps during this time (i.e. hot light fixtures will significantly reduce seed set, even when the stalks are several inches away.
Propagation Techniques

Seed: generally easy. no cold stratification required. Can be grown to flowering maturity from seed in about 1-1.5 years if fed approx. every 2 weeks.
Leaf-cuttings: easy. water floating method works best. Place directly under lights for the hightest success rate. See picture to left
Root cuttings: easy. Roots are a bit more slender than most South African sundews, but they work just as well.
Divisions: easy. D. affinis may form clumps over time. Drosera affinis has no trouble dealing with repotting and root disturbance, so divisions can be taken easily.
