Summer Blooming Shrubs
Lavandula angustifolia ‘Hidcote'
Evergreen shrub with narrow gray-green foliage and deep purple fragrant flowers forming dense mound. Grows 18–24 inches tall, tolerates pruning, ideal for low hedges, borders, and edging. Zones: 5–9.
Summer blooming shrubs carry the garden through its most colorful season, producing waves of blooms when many spring flowers have faded. Their blossoms span a wide range of hues and forms, from airy clusters to dense panicles, often set against full, leafy growth. These shrubs provide lasting interest in borders, foundation plantings, and mixed landscapes, with many continuing to flower well into late summer.
Selected for reliable performance and extended bloom time, they contribute both structure and seasonal color during the warmest months. Some attract pollinators with nectar-rich flowers, while others add texture through foliage or growth habit. Whether used as focal points or woven into larger plantings, summer bloomers help maintain continuity and visual interest across the growing season.
