Family

Ericaceae

Botanical Name

RHODODENDRON 'Northern Hi-Lights'( NORTHERN LIGHTS SERIES)

Plant Common Name

Deciduous Azalea, Northern Hi-Lights Azalea

General Description

Valued for their extreme hardiness and their colorful spring flowers, the Northern Lights Series is a group of hybrid deciduous azaleas developed by the University of Minnesota. The fragrant, trumpet-shaped flowers of 'Northern Hi-Lights' are creamy white with a bright yellow upper petal. The clustered blossoms open from yellow buds from mid- to late spring. This dense broadly rounded shrub has oval olive-green leaves that turn maroon in fall.

Plant this azalea in full to partial sun in acidic humus-rich soil. Excellent drainage is required. An airy organic mulch will keep the shallow roots moist and cool. Northern Lights azaleas are wonderful specimens for cold-climate gardens, best shown off against dark evergreens such as hemlocks. They are also lovely mixed together for a breathtaking spring display of contrasting flower colors.
