Hydrangea aspera 'Rosemary Foster' is a delightful compact shrub that brings a vibrant touch to temperate gardens with its striking foliage and enduring lacecap flowerheads. The plant showcases long, finely serrated leaves that start off in a rich chocolate hue, transitioning to a sophisticated grey-green adorned with wine-red undersides as they mature. As autumn approaches, these leaves take on a beautiful bronze tone, ensuring that the shrub remains visually appealing throughout the seasons. This remarkable color transformation adds depth and interest to any garden setting, making it a versatile choice for various landscaping designs.
From June to September, 'Rosemary Foster' produces stunning flat corymbs composed of violet to violet-pink fertile florets, which are artfully interspersed with larger, nearly white sterile florets. This unique floral display not only enhances the aesthetic appeal of the shrub but also attracts pollinators, contributing to the overall health of the garden ecosystem. Notably, the color of both the flowers and foliage remains consistent regardless of soil pH, allowing gardeners to enjoy its beauty without the worry of soil conditions. Its compact and bushy growth habit makes it an excellent candidate for borders, woodland gardens, or even container arrangements, providing flexibility in garden design.
To thrive, Hydrangea aspera 'Rosemary Foster' prefers moist, well-drained soil and partial shade to full shade, while also demonstrating a tolerance for lime. Hardy in the UK down to approximately ?12 °C, this shrub is well-suited for various climates. To promote lush foliage and abundant flower heads, it benefits from organic-rich soil and a summer mulch. Maintenance is straightforward; a simple pruning after flowering to remove old flowerheads and occasional stems is all that is required. However, it is important to handle this plant with care, as all parts are toxic if ingested. With its low maintenance needs and stunning visual appeal, 'Rosemary Foster' is a wonderful addition to any garden. Height: 120 cm (47 in) Spread: 120 cm (47 in)
