RHODODENDRON. (Ericaceae, Heath Family) 
The Rhododendrons, including those usually called Azaleas, listed below are low, | 
slow growing or spreading kinds and are well adapted to the rock garden. All will | 
stand full sun as well as light shade and all require a sandy or peaty acid leafmold | 
soil. (pH 4-6) This is by no means a comprehensive list of Rhododendrons. There are | 
many more in nature and available in the trade but we have not yet tried them and | 
other that we have tried have been eleminated because of being too tender for a list 
of hardy plants. ; 
Rhododendron impeditum. A very dwarf, compact bush about 18 inches high at maturity. 
This rare species from China has tiny oval evergreen leaves on short stiff branches 
and clusters of little lavender flowers in May. Color HCC 637, Sea Lavender Violet. 
Rhododendron indicum balsaminaeflora. (Azalea) A compact, slow growing, spreading 
dwarf Azalea about 12 inches high, gayly adorned with large fully double rose 
flowers in late May and June. Color, HCC 620/1, Porcelain Rose. This is about the 
prettiest azalea for the rock garden but it needs winter protection north of New 
Y orks City: 
Rhododendron indicum hakitishiro, An extremely dwarf or prostrate Azalea that forms 
low, dense plant about 5 inches high with very large single pure white flowers in 
May. Another rather tender variety that needs winter protection. It is dependable 
in sheltered places. 
Rhododendron June Dawn, An evergreen hybrid Azalea with small hairy leaves on a 
compact twiggy shrub up to 3 feet high. It can be trimmed to any desired height. 
The very large bright pink flowers are produced late in June. making this a very 
desirable addition to the rock garden. It is perfectly hardy anywhere.
