Rich purple flowers cover this evergreen in spring on a plant that handles summer heat better than most rhododendrons. This Proven Winners® selection, Rhododendron 'LAVJ2011', sold as Dandy Man® Purple, grows 6 to 8 feet tall and wide in part shade, hardy from Zone 4 through Zone 8.
It resists root rot and leaf spot, the two problems that most often shorten a rhododendron's life in humid climates.
The large-leaf rhododendrons hold their foliage year-round rather than thinning like the small-leaved types. Below about 25 degrees the leaves droop and curl up, curling tighter the colder it gets, and they open again within hours once temperatures rise. It looks alarming the first winter and it is entirely normal, a water-conserving response rather than a sign of trouble.
At six to eight feet this is a screening shrub rather than a foundation plant. Acidic soil is necessary, roughly pH 4.5 to 6.0, with good drainage and steady moisture. Mulch the shallow roots.
