Easily
grown and propagated, the shrubby mallows have the further
advantage of a long flowering season. A Trial at Wisley provided
the opportunity to look into the origins of some of the new
cultivars. This research has culminated in the publication
of a paper, Genetic and morphological analysis of the origin and identity
of perennial Lavatera (Malvaceae) cultivars in the Journal of the American Society for Horticultural Science.
