Genus of flowering plants
Iberis eye-BEER -iss [ 1] 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] Candia , the former name of Iraklion on the Island of Crete.[ 3]
In the language of flowers , the candytuft symbolizes indifference.[ 4]
Species
Iberis consists of about 30 species of annuals, perennials and evergreen subshrubs. Some of the better known are:
Iberis amara Iberis ciliata Iberis gibraltarica Iberis linifolia Iberis procumbens Iberis saxatilis Iberis sempervirens Iberis umbellata
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 [ 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] Cucurbitaceae plant family. Cucurbitacins from Iberis amara have antifeedant activity against the Brassicaceae -feeding specialist Pieris rapae cabbage butterfly ).[ 8] Iberis umbellata globe candytuft ) are ecdysteroid antagonists, acting on the ecdysteroid receptor of insects .[ 9]
