Iberis /aɪˈbɪərɪs/,[1] commonly called candytuft, is a genus of flowering plants belonging to the family Brassicaceae. It comprises annuals, evergreen perennials and subshrubs native to the Old World.[2] The name "candytuft" is not related to candy, but derives from Candia, the former name of Iraklion on the Island of Greece.[3]

In the language of flowers, the candytuft symbolizes indifference.[4]


Iberis consists of about 30 species of annuals, perennials and evergreen subshrubs. Some of the better known are:

Iberis amara - rocket candytuft, bitter candytuft, wild candytuft
Iberis ciliata
Iberis gibraltarica - Gibraltar candytuft
Iberis linifolia
Iberis procumbens - dune candytuft
Iberis sempervirens - evergreen candytuft, perennial candytuft
Iberis umbellata - globe candytuft

They are used as ornamental plants for rock gardens, bedding, and borders in full sun or light shade.

Trophic connections

These plants provide nourishment for a number of insect species of which the rare Euchloe tagis butterfly is the most striking example as it is monophagous on species in this genus. [5][6]

Biochemical defenses

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).[8] Cucurbitacins from Iberis umbellata (globe candytuft) are ecdysteroid antagonists, acting on the ecdysteroid receptor of insects.[9]
