Larger, rounded shape. Matches Formosa purple hue. Robust compared to some. Great contrast between variable flowers and dark green foliage

What a great reblooming azalea. It blooms heavy in the Spring and again in the Fall. Sporadic blooms rest of the year. It has blooms of either solid color, or blooms with stripes or blotches of color all on the same plant. Needs acidic soil and kept moist as all potted azalea's. Takes full sun to light shade. Rich dark green foliage. Have mine as a potted plant on the deck year round, could be planted in the ground in well drained soil. Individual blooms are about 2 inches across. Plant has upright growth habit.
