Ludwig Spaeth is a classic French lilac cultivar known for its richly colored, deep reddish-purple blooms and strong, sweet fragrance. Blooming in late spring, it produces long, narrow panicles packed with single florets that open from dark buds, making it one of the most vibrantly colored lilacs available. Its bloom time extends the lilac season and provides a stunning contrast to paler varieties in the landscape.
This upright, multi-stemmed shrub grows 8 to 10 feet tall and 6 to 8 feet wide, making it an excellent choice for hedging, screening, or as a bold focal point. Like other Syringa vulgaris cultivars, it thrives in full sun and well-drained, neutral to slightly alkaline soil. It’s cold-hardy and deer-resistant, and light pruning after bloom helps maintain shape and vigor.
