Globe Candytuft (Iberis umbellata)
Description
The biological form of Iberis umbellata is hemicryptophyte scapose, as its overwintering buds are situated just below the soil surface and the floral axis is more or less erect with a few leaves. The stem is twisted at the base while the flowering branches are erect and leafy. This plant reaches a height of 30-50 centimetres (12-20 in). The leaves are green and linear-lanceolate, 15-25 millimetres (0.59-0.98 in) long. The flowers are in umbel-shaped corymbs. The calyx is violet and the corolla is composed of four white, pink or purple petals. The petals are rounded at the apex, with the peripheral ones forming a large vexillum 8-10 millimetres (0.31-0.39 in) long. The flowering period extends from May through June. The flowers are hermaphroditic and pollinated by bees and butterflies. The fruit is a silique 7-10 millimetres (0.28-0.39 in) long.
