Gibraltar candytuft description

KingdomPlantae
PhylumTracheophyta
ClassMagnoliopsida
OrderCapparales
FamilyBrassicaceae
GenusIberis (1)

A low-growing wildflower, the Gibraltar candytuft (Iberis gibraltarica) is an abundant evergreen shrub that is native to the island of Gibraltar (2). A perennial species, the Gibraltar candytuft has green, fleshy leaves which may be oblong, wedge- or spoon-shaped, with distinctly toothed tips and a slight covering of fine hairs (3) (4).

The Gibraltar candytuft produces large, showy flowers of pink, pale lavender or white, sometimes suffused with red (3) (4) (5). Four petals form the shape of a cross, although the two inner petals have developed to become much larger than the outer petals (5). The lower outer flowers open first and have longer stems than those towards the middle, creating a beautiful flat-topped inflorescence which covers the entire plant when it is in bloom (5)

Part of the common name of this species, ‘candytuft’, was originally given to Iberis umbellata, from Crete, and is derived from ‘Candia’, the old Venetian name for Heraklion, the capital of Crete (5).
