Plant Common Name

Evergreen Azalea, Michael Hill Evergreen Azalea, North Tisbury Hybrid Azalea

General Description

The North Tisbury azalea ‘Michael Hill' bears lovely large deep shrimp-pink flowers in late spring. The funnel-shaped single blooms have burgundy speckling on their upper lobes. This dense broad ground-hugging plant has small elliptic glossy-green leaves that are bronze-tinged in fall and winter.

North Tisbury Hybrids are low-growing evergreen azaleas introduced by Polly Hill of Martha's Vineyard, Massachusetts. Like most North Tisbury cultivars, 'Michael Hill' is a hybrid of Rhododendron nakaharai, a prostrate evergreen azalea from Taiwan.

These azaleas prefer partial shade and highly organic acid soil that is evenly moist but well-drained. Plant them shallowly and mulch well to conserve moisture and suppress weeds. They favor warm summers and cool winters and require some winter cold for good growth. The flower buds develop in summer for the following spring’s display, so prune shortly after flowering, if necessary. Ideally, place them where they will not requre pruning.

North Tisbury azaleas make wonderful specimens, edgers, small-scale ground covers, or container plants for partial shade.
