Rhododendron catawbiense 'Album' (H-1)

SKU
00900
Stunning clusters of white trumpet-shaped flowers in mid-spring. Large, narrow, dark green foliage cloaks the upright, rounded form. One of the hardiest and most dependable, this classic Ironclad rhododendron is sun and shade tolerant but thrives as an understory shrub in a dappled sun position. Evergreen.

Provide organically rich, acidic, well-drained soil with a thick layer of mulch to keep roots cool, avoiding the crown. Protect from harsh afternoon sun. Water deeply, regularly during the first growing season to establish an extensive root system; once established, prefers evenly moist but not soggy soil. Apply an acid fertilizer after bloom.
