Convolvulus sabatius

Convolvulus sabatius

Previously called Convolvulus mauritanicus, this is a trailing groundcover with shallow, funnel-shaped flowers usually of a milky-blue hue, but sometimes seen in darker blue colours or white. The white cultivar 'Little Arctic Moon' is a compact form with a neat habit, and it has done well for me. It blooms throughout summer and autumn. It needs good drainage and plenty of sun - it will sulk in shaded spots.

It looks at its best cascading over a retaining wall or a sunny bank. It doesn't really want rich soil; a gritty, well-drained soil suits it best. It could be grown in a hanging basket. It is native to Spain, Italy and North Africa. Cut it back in early spring. It can become a bit rampageous so I rein it in from time to time. I have had more luck with this plant than with its cousin Evolvulus pilosus, which hasn't done well for me.
