Rhododendron 'Hoopla' is a distinctive, broadleaf evergreen rhododendron selected for spring flower trusses with wavy petals and bright, playful color. You can use it as a specimen, in a mixed shrub border, or as a flowering screen where you want year-round structure and a bold seasonal show. Mature size is typically about 60-72 inches tall with a similar spread (about 60-72 inches), so give it room to develop its naturally rounded, upright form.
Site it in partial shade for best performance, especially where it will get morning sun and protection from hot afternoon sun. It can handle more sun in cooler climates when soil moisture is consistent, but filtered light is ideal. Provide shelter from harsh winter wind to reduce leaf scorch, and avoid exposed, reflective locations that dry the plant out.
Plant in well-drained, acidic soil rich in organic matter. Keep the root zone evenly moist, particularly during establishment and dry spells, but do not leave it in waterlogged ground. A layer of mulch (pine needles, shredded bark, or leaf mold) helps keep roots cool, holds moisture, and supports the acidic conditions rhododendrons prefer. Water at the base and keep mulch pulled back slightly from the stem to discourage rot.
Maintenance is simple: remove spent flower trusses after bloom if you like a tidy look, and prune right after flowering if shaping is needed. Avoid heavy late-season pruning so you do not remove next year's buds. In USDA Zones 4-8, consistent moisture, good drainage, and afternoon shade help this shrub look its best year after year.
