Cleome 'Violet Queen' Overview

Cleome houtteana 'Violet Queen' is a half-hardy annual cultivar that produces showy clusters of purple flowers in summer which contrast attractively against the green foliage on hairy spiny stems. Commonly known as Spider Flower or Spider Plant, this species has been classified as Cleome spinosa and Cleome hassleriana and is still occasionally sold under these names. This species is part of the Royal Horticultural Society “Plants for Pollinators” initiative to showcase plants which support pollinator populations by providing ample amounts of nectar and/ or pollen. A great choice for encouraging pollinating insect wildlife into your garden!
