Convolvulus sabatius, the ground blue-convolvulus[1] or blue rock bindweed, is a species of flowering plant in the family Convolvulaceae, native to Italy and North Africa, and often seen in cultivation.[2]

Description

It is a woody-stemmed trailing perennial plant, growing to 20 cm (8 in) in height.[3] It has slightly hairy leaves and light blue to violet flowers, often with a lighter centre, which is 2.5–5 cm (1–2 in) in diameter.[3] The stem is decumbent to ascending and non-twining. The leaves are all entire. The base of the leaf blade is slightly heart-shaped and truncate to wedge-shaped. The corolla is 15 to 22 millimeters long and blue to pink.

The Latin specific epithet sabatius refers to the Savona region of Italy.[4]

Cultivation

This species is often sold under the synonym C. mauritanicus. Although a perennial, it is best treated as an annual in colder climates.[3] It is suited to window boxes and containers and prefers a sunny situation with good drainage. Tip pruning encourages new growth and flowering.[3] It has gained the Royal Horticultural Society's Award of Garden Merit.[5]
