The pale blue blooms and curiously shaped seedpods of fennel flower (Nigella sativa)—also known as black seed, black cumin, and kalonji—aren’t as showy as those of its close relative, love in a mist (N. damascena), but this pretty species offers a bonus feature: edible seeds that are used as a cooking spice. It also has a history of some interesting medicinal properties. The plants reach about 10 inches tall in flower and bloom in summer from an early sowing or fall from a summer sowing. Full sun to light shade. Annual.
A side note: I’ve noticed that a number of websites that sell these seeds or discuss the uses of this plant show photos of Nigella damascena, not this species: N. sativa. The photos here are from my own garden, so you can see you are getting the true edible-and-medicinal species.
Collected in August and September 2020. At least 20 seeds.
