- A mucronatum hybrid: This cultivated hybrid azalea was grown in Japanese gardens over 300 years ago, but is not found in the wild. Commonly called 'Indica Alba' or 'Ledifolia Alba', it was introduced from China into England in 1819. The hybridizer of ‘Delaware Valley White’ is unknown. It is sometimes listed as a Glenn Dale azalea, however, it does not appear in the corrected list of Glenn Dale Azaleas published by Galle (1985, p. 235-251).
