Gardeners' Notes:

This is a small sprawling rhododendron. I bought mine at wal-mart. the foliage is a dark purple throughout the year (which looks almost black against green foliage), but turns a vibrant magenta-purple in the wintertime(Nov-Dec) just before it blooms( which happens in Jan). I have found it quite drought tolerant and it tolerates full sun. Mine is growing in z9b CA.
