Neon Flash Spirea

Neon Flash Spirea (Spiraea japonica 'Neon Flash')

Neon Flash Spirea (Spiraea japonica 'Neon Flash') is a vibrant, deciduous shrub prized for its intense red-pink flowers and dynamic foliage that changes color throughout the season. Also known as Neon Flash Spiraea, this durable and colorful shrub provides long-lasting bloom and seasonal interest, making it a bold focal point for borders, foundations, and mass plantings in high-visibility areas.

Distinctive Features

Neon Flash grows 2 to 3 feet tall and wide with a dense, rounded habit. New foliage emerges with a red-bronze tint in spring, maturing to dark green in summer, and then shifting to red and burgundy in fall. In early to midsummer, it produces clusters of bright neon pink flowers that stand out against the foliage and attract butterflies and other pollinators. With light deadheading, it may continue blooming into late summer.
