Rhododendron Anna H Hall

Anna H. Hall Rhododendron

Anna H. Hall (Rhododendron ‘Anna H. Hall’) is an evergreen rhododendron with white flowers. Its display arrives near the middle of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 2 inches across. The blooms open with a bell-like outline. Clusters commonly carry about 14-15 blossoms.

The plant develops compact branching and a dense crown. A fine covering beneath the leaves adds detail to the foliage at close range. It can provide a flowering focal point within a mixed shrub border or woodland-edge planting.

This cultivar tolerates sun, with light shade useful in hotter positions. Provide acidic, humus-rich soil with good drainage, maintain moisture during dry weather and keep mulch away from the stems.
