|The Belgian Indica azaleas are the result of crosses between many different species, including R. simsii, R. mucronatum, and R. indicum. They were originally bred as greenhouse forcing plants.
'Festival Queen' is also the name of another Belgian Indian hybrid from Australia/New Zealand, with large white semidouble flowers. Small, bushy, evergreen azalea with lush, glossy, dark green leaves, 1 1/4 to 1 3/4 inches long. Flowers are borne profusely in large, showy trusses from late winter to early spring. Plant as you would any of the other azaleas: high and in well-drained, acid soil, rich with organic matter. Excellent choice for growing indoors in containers. Can be grown outdoors where winter temperatures do not fall below 20 degrees F.
