Seed pod short and curved upwards on longer stalk may or may not have short leaf-like bracts nearby. Stem ridged for rigidity; lower part may turn woody too.


Some similarities to : the rather rare Wild Candytuft which is found mainly in the Chilterns but that has zygomorphic flowers particularly on the peripheral of the flowering spike where the two outer petals are much longer than the two inner flowers of the very same floret.

Not to be confused with: Garden Candytuft (Iberis umbellata), which is another Candytuft popular with gardeners, but which is much larger and bushier, with flowers of various colours such as mauve and lilac rather than only in white.

Rounded flower-head not un-like that of Sweet Alison, a member of the same Cabbage Family.

Uniquely identifiable characteristics

Distinguishing Feature :

Is grown mainly as a garden plant. Likes walls. May escape to nearby places.

It is a highly distinctive plant belonging to the Cabbage Family, but has a most unusual flower shape with four petals, in pairs, of un-equal length, arranged not in a right-angled cross but like an 'X' chromosome. Seed pods cylindrical, short and curved upwards. There is no basal rosette of leaves.
