Tri-Lights Azalea (Rhododendron 'Tri-Lights')

Tri-Lights Azalea (Rhododendron 'Tri-Lights') is a striking deciduous azalea from the Northern Lights series, known for its bicolor flowers and excellent cold hardiness. Developed by the University of Minnesota, this variety offers a vibrant and unusual floral display in mid to late spring, with multicolored blooms that bring brightness and texture to cold-climate landscapes. Its upright habit and reliable performance make it a strong candidate for focal points, mixed shrub borders, and woodland edges.

Foliage is medium green through summer and takes on warm tones in fall.
