Tall, narrow, sparsely-leafed stems bear flattened heads of bright lavender-purple flowers that provide useful height in a herbaceous border. This is a short-lived perennial, and because it is borderline hardy, plants may be damaged by winter frosts. This may be avoided by leaving the dead stalks until spring, when new growth is evident, before cutting them back. A protective mulch should be added around them in the autumn with leaf mould or compost. They do, however, self-seed liberally and resulting seedlings are stronger and more drought-tolerant than those that are transplanted. This is a superb butterfly plant, rivalling even buddleja. The Royal Horticultural Society have given it the Award of Garden Merit. : http://www.bbc.co.uk/gardening/plants...

This species grows best in a well-drained soil. It prefers full sun to partial shade and needs regular moisture. It has a reputation of rarely being attacked by insect pests, but may be susceptible to powdery mildew. V. bonariensis is commonly grown from seed which germinates readily without pre-treatment, but can also be propagated from herbaceous stem cuttings. It has gained the Royal Horticultural Society's Award of Garden Merit. See more: http://en.wikipedia.org/wiki/Verbena_...
