History & Lore
History:
A U.S. National Arboretum Plant Introduction, Helene is a sterile triploid with a more compact form than the species Hibiscus syriacus. In 1971, a number of crosses were made between diploid Hibiscus seedling selections of (H. syriacus 'Suminokura-yae' x H. syriacus 'William R. Smith'),(H. syriacus 'Blue Bird' x H. syriacus 'Hanagasa'), or (H. syriacus 'Sokobeniyae' x H. syriacus 'William R. Smith') and colchicine-induced tetraploid seedlings ofH. syriacus 'William R. Smith'. The resulting triploids, 'Helene', 'Minerva', and 'Aphrodite' were released in 1980, 1986 and 1988, respectively.
