This is probably the most invasive garden plant you can grow in the U.K., or you could call it the prettiest 'weed' you can grow. This plant has all the bad habits of its uglier U.K. relatives - but it is very beautiful!
I think the only way to grow it is either in a large tub or in a bed on is own in the middle of a lawn (it can't compete with grass).
There is a variety called tenuissimus which has silvery, deeply divided leaves and paler peppermint pink flowers.
I like the normal plant more than the variety 'tenuissimus', because the flowers look slightly redder. If you can, try growing it from seed collected from the wild because flower colour can vary - I reared one plant which had flowers of a brighter reddish violet pink.

Convolvulus has trailing twining stems and spreads by underground rhizomes. The flowers are bright pink and appear in late spring and summer. Many think that Convolvulus are morning glories...they are not; the morning glory species is ipomoea. The flowers of Convolvulus stay open all day and blooms profusely. May be invasive in warmer climates. Should be supported. Best cultivated in full sun in any moist well draining soil. Deadhead to promote more flowering and thicker growth. Propagate by cuttings. Hardy zones 8-10.
