Golden-eyed adults that mostly drink; larvae that hunt like small alligators.

, Ladybugs

Ladybugs

Growing from seed

Start Serrano indoors about 10 weeks before your last frost, keeping seeds in warm soil (around 20–25 °C). Seeds usually come up in around 14 days. Move seedlings out once the danger of frost has passed, in full sun, spaced about 45 cm apart. Expect to harvest in roughly 75 days.

Serrano seed rarely stays viable beyond 2 years — track what's still worth sowing.
