Most of David Leach’s azalea hybrids have the same pedigree: Rhododendron arborescens x cumberlandense. These are some of our favorite azaleas at the David G. Leach Research Station. In 2013 Dr. Stephen Krebs remade this cross and grew out seedlings, and we have 30 one-of-a-kind seedlings available for sale this year. Rhododendron arborescens is tall and has fragrant white flowers. Rhododendron cumberlandense is shorter and has non-fragrant orange-red flowers and blooms a bit later than the earliest native azaleas. Who knows what you’ll get? These plants were given cross number 13-185 in our records, meaning it was the 185th cross of 2013.
