Lagerstroemia speciosa (L.) Pers. is one of 30–50 species (Furtado and Montien, 1969) of this Asian genus, from which L. indica and its hybrids have become mainstays of horticulture (Cabrera, 2004). Commonly called Pride-of-India, queen’s or giant crape myrtle, L. speciosa can attain heights of 20 to 30 m in the wild. It is valued as a timber tree, and a tropical ornamental, with landscape utility limited to USDA Hardiness Zones 10–11 (Everett, 1980; Gilman and Watson, 1993; U.S. Department of Agriculture, 2012). It is native to India and elsewhere in Southeast Asia, but has been introduced into tropical areas all over the world. The flowers, arguably the largest in the genus, are most typically purple, with pink the second most common color. Additional observed variants include light lavender to white. This paper describes a pink-flowered seedling selection of the species that has the largest flowers observed on any clone of the species encountered by the authors.
