Serotina boasts beautiful crimson red blooms on blue green foliage all summer long, making it one of the most sought after honeysuckles available. The transforming blooms start out crimson, changing to a dark red with bright yellow and white inner petals. The highly fragrant flowers are irresistible to butterflies and hummingbirds. This well-behaved type is not the same as the invasive Japanese honeysuckle, but will still quickly cover arbors, trellises, walls, or fences. Full to Part Sun.
