About the Image

White-flowered form of Syringa vulgaris from the Arnold Arboretum of harvard University. Several hundred cultivars of lilacs were developed from 22 wild species through extensive hybridizatino and artificial selection. The parentage of several of these hybrids was confirmed using restriction site analysis of both chloroplast and nuclear ribosomal DNA.
