Genus Iberis species are garden plants in Finland and can be found particularly in rockeries and to a certain extant as escapes from there. Among the most common escapes in the genus are wild candytuft and globe candytuft (I. umbellata). The name of the genus is a big hint that the plant originates from or is at least common on the Iberian Peninsula (Spain and Portugal). Wild candytuft’s species epithet amara (lat. amarus) refers to its bitter flavour.
Globe Candytuft (Garden Candytuft)
Globe candytuft’s species name umbellata is a good description of the structure of both of these plants’ flowers. Globe candytuft’s flowers are slightly larger and a darker red (often lilac) than those of globe candytuft, the leaves have entire margins and the silicula wings and tip are clearly longer.
Sweet Alison (Sweet Alyssum)
Sweet alison is a garden plant and an escape looking a lot like candytufts. Small white flowers form clusters. Fruits are quite small (2–3.5 mm across) disc-like siliculae.
