~30; see text Iberis (/aɪˈbɪərɪs/ eye-BEER-iss),[1] commonly called candytuft, is a genus of flowering plants belonging to the family Brassicaceae.

[2] The name "candytuft" is not related to candy, but derives from Candia, the former name of Iraklion on the Island of Crete.

[4] Iberis consists of about 30 species of annuals, perennials and evergreen subshrubs.

[5][6] Species in the genus Iberis contain not only glucosinolates, which are characteristic chemical defenses of the Brassicaceae plant family, but also cucurbitacins,[7] which are better known as chemical defenses in the Cucurbitaceae plant family.

Cucurbitacins from Iberis amara have antifeedant activity against the Brassicaceae-feeding specialist Pieris rapae (cabbage butterfly).
