Itea virginica 'Merlot'

The Story

Plant Bio

Itea virginica is a deciduous shrub native to the eastern U.S., celebrated for its fragrant, drooping flower racemes in summer and brilliant fall color. It spreads by suckers to form colonies.

'Merlot' is a compact cultivar noted for its brilliant wine-red fall color, which is more intense and consistent than the species. Its smaller stature makes it suitable for a wide range of garden applications.

Uses & Benefits:

'Merlot' offers multi-season appeal with fragrant white summer flowers that attract pollinators, lush green summer foliage, and stunning, reliable wine-red color in the fall.

Its tolerance for wet soils makes it a superb choice for rain gardens, boggy areas, and stream banks. It can be massed for erosion control on moist slopes and forms a dense, low-maintenance groundcover.

As a native plant, it supports local ecosystems. The flowers are a valuable nectar source for native bees, butterflies, and other beneficial insects. Its thicket-forming habit provides cover for wildlife.
