Buddleja indica Lam. is encountered frequently as a houseplant or a conservatory specimen and is attractive ornamentally for its oak-shaped foliage. Buddleja indica, a tetraploid African species, 2n = 76, was crossed to the Asiatic tetraploid species B. davidii Franch. The F1 generation was intermediate in foliage character between the two parents. Flowers of the F1 were either white or light lavender in color and the number of flowers per inflorescence was intermediate between the parents. The F1 plants were fertile. These hybrids might be suitable for greenhouse or container culture due to their attractive foliage and floral display.
