Whorled Leaves

Rosie Lerner, Extension Consumer Horticulturist, Department of Horticulture & Landscape Architecture, Purdue University

Most gardeners are familiar with plants that have alternate or opposite leaves. But many are not familiar with the term "whorled" leaves, meaning three or more leaves at each node. Some examples common to Indiana gardens and landscapes include Lysimachia (yellow loosestrife), Eupatorium (Joe pye weed), Veronicastrum, and Galium (bedstraw).
