Variedades de Azaleas

Azaleas are either species or hybrids. A species is a population that interbreeds and is reproductively isolated from other populations. Seedlings from such isolated species populations look like the parents, or "grow true from seed". Hybrids are crosses between other species or hybrids. Hybrids will not grow true from seed and may be faithfully reproduced only from cuttings, which are clones of the mother plant.

Azaleas have been hybridized for hundreds of years. Over 10,000 different azalea plants have been registered or named, although far fewer are in the trade. This provides a very wide variety of plant habits, sizes, colors and bloom times to meet almost every landscaping need or personal preference.

All North American species azaleas, also called native azaleas, are deciduous (drop their leaves in the fall), with flower colors ranging from white to purple, pink, red, orange and yellow. Evergreen azaleas, native primarily to Japan, have flower colors including white and various shades of purple, pink, red and reddish orange, but not yellow. Color patterns include single colors and bicolors as well as sectors, stripes and flecks. For many azalea varieties, all the flowers on the plant are similar. For other varieties, the flowers on the plant may be a mixture of color variations, with a different mixture from one year to the next.
