Sir Robert Azalea
Rhododendron  'Sir Robert'

USDA Plant Hardiness Zones: 6a-9a (5a?)  Find Your Zone


Note:  For our customers who live and garden north of USDA Plant Hardiness Zone 6a, where this Azalea variety is not reliably winter hardy outdoors, you can enjoy it in containers that can be moved indoors during winter and placed back outside when temperatures warm up in spring.




Special Attributes

'Sir Robert' is a Robin Hill hybrid azalea that produces an abundance of beautiful large white flowers brushed and striped in soft pink, purple and/or peachy-pink with a rose-purple spotted blotch. Occasionally, you might see a solid rose pink flower. Needless to say, this azalea is a conversation piece when in bloom from late spring through early summer.  Attractive dark green, glossy evergreen leaves on dwarf and rounded form.




Landscape & Garden Uses

Growing in a rounded mound 2-3 feet tall and 3 to 4 feet wide at maturity, Sir Robert Azalea is ideal for use as a specimen in small garden spaces and containers 14 inches or more in diameter. Plant it in small groupings, mass plantings or as a border along paths and walkways in landscape and woodland borders and home foundation plantings. A fine addition to Asian-theme gardens, Azalea gardens, cottage gardens, and partially shaded woodland gardens. 

Spacing:  2.5 to 3' for solid hedges;  6' or more for space between plants





Cultural Preferences

Evergreen Azaleas are easy to grow when planted right and in the right spot. They prefer a moist but well-drained and acidic soil that is rich in organic matter and part sun. Morning sun with afternoon shade or filtered sun is ideal. Moderate drought tolerance when established.
