With Itea virginica 'Fountains of Rouge™' (Virginia Sweetspire 'Fountains of Rouge™'), you get a dependable native shrub that delivers seasons of interest in a manageable size. In late spring to early summer, it produces showy, fragrant white flower racemes that draw pollinators. As the season turns, the foliage develops rich red tones for standout fall color. At maturity it typically reaches about 36-48 inches tall with a graceful, arching habit and a broad, full spread.
Plant it where the soil stays evenly moist for best growth and color, but it is adaptable and can handle a range of conditions, including periodically wet sites. It can be a great fit for rain gardens, pond edges, and low spots, and it also performs well in average garden beds when mulched and watered during dry spells. Provide full sun to part shade; more sun generally improves flowering and fall color.
Because Virginia sweetspire can produce suckers, give it room to naturalize, or simply remove unwanted shoots to keep it tidy. Prune right after flowering if you need to shape it, since buds form on older wood. A layer of mulch helps protect roots and keeps moisture consistent through summer heat.
