Summary

Breeding plants to encourage specific traits is usual in agriculture but less common in ornamental horticulture. Daffodils, daylilies, hostas, lilacs, magnolias, and rhododendrons are among the 15 subjects covered by experts in the field.

Author Biography

Husband and wife Brett and Dorothy Callaway both received their B.S. degrees in horticulture at the University of Georgia, and advanced degrees (Brett a Ph.D. in plant breeding, Dorothy an M.S. in botany) at Cornell University. Brett is now a corn breeder/geneticist; Dorothy is international registrar for Magnoliaceae and editor and member of the board of trustees of the Magnolia Society
