|The Carla (North Carolina-Louisiana) Hybrids originated at North Carolina State University in Raleigh, N.C., with the goals of better resistance to root rot diseases, drought and cold. These hybrids, whose parentage includes Kurume, Kaempferi, Belgian Indian and Satsuki hybrids, are medium to large evergreen shrubs with a vigorous growth habit. Flowers are borne in mid spring in showy trusses of up to four blooms.
Plant as you would any of the other azaleas: high and in well-drained, acid soil, rich with organic matter. Though azaleas have a potentially large list of possible pest and disease problems, they are usually trouble free if planted correctly in proper cultural conditions.
