Growing from Seed
Sickle Senna is one of those generous plants that come along well from seed. Sow seed into a loose, well-drained mix and keep it warm and consistently moist, since this tropical species does best with steady warmth. Bright light suits this fast-growing annual well, and it typically matures and sets its distinctive curved seed pods within a single warm growing season. Scatter the seed evenly over a loose seed compost, cover to no more than its own depth, and keep the pot moist and bright. Once the seedlings have made true leaves, pot them on individually and plant out when they are sturdy and conditions are right.
Our Take
Once established, Sickle Senna largely looks after itself. Sickle Senna has real presence in the garden without demanding much in return. Plant it in sun with drainage to its liking and the rest is easy.
