The Gibraltar candytuft has not yet been classified by the IUCN.

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).

The Gibraltar candytuft is native to the island of Gibraltar in southern Europe (5) (6).

In the wild, the Gibraltar candytuft is common among crevices on the north face of the Rock of Gibraltar (5). It appears to prefer warm spots on banks or rocky places (2), and thrives in poor, dry soils (4).

The Gibraltar candytuft is known to flower in early spring (3) (5). Very little else is known about the biology of the Gibraltar candytuft.

There are no known major threats to the Gibraltar candytuft and it is not currently considered at risk of extinction.

There are no known conservation measures in place which specifically target the Gibraltar candytuft.
