|'Delaware Valley White' is a clone of 'Mucronatum,' an old Japanese cultivated azalea of the Ryukyu Azalea Group. 'Mucronatum' is often erroneously listed as a separate species, R. mucronatum, and is commonly sold as 'Indica Alba' or 'Ledifolia Alba.'
Broad, spreading, semi-evergreen shrub with small, lanceolate to ovate, hairy green leaves. Scented flowers are borne in showy trusses of two or three blooms in mid-spring. Thrives in full sun.
Plant as you would any of the other azaleas: high and in well-drained, acidic 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.
