Description
Agapanthus Intermedia
Agapanthus Intermedia is a magnificent deciduous Agapanthus producing exceptionally rounded heads of rich dark blue flowers above bold clumps of green strap-shaped foliage. Flowering from mid to late summer, this vigorous variety is one of the tallest and most impressive Agapanthus available, making a spectacular focal point in borders, large containers and architectural planting schemes.
Agapanthus Intermedia Features
Throughout the flowering season, Agapanthus Intermedia produces medium flower heads packed with numerous dark blue florets carried on tall, sturdy stems. Furthermore, the impressive blooms rise well above the foliage, creating dramatic height and visual impact within the garden. As a result, this variety is ideal for adding structure and long-lasting colour to sunny planting schemes.
The attractive green foliage forms substantial clumps throughout the growing season, providing texture and contrast for the striking flowers. Additionally, the nectar-rich blooms attract bees and other pollinating insects throughout summer. Consequently, Agapanthus Intermedia offers both ornamental beauty and valuable wildlife benefits.
Growing Agapanthus Intermedia
For best results, plant Agapanthus Intermedia in a sunny position with fertile, moist but well-drained soil. It performs exceptionally well in borders, raised beds and large decorative containers. Moreover, regular watering and feeding during the growing season will encourage vigorous growth and abundant flowering.
As a deciduous variety, the foliage dies back naturally in autumn before fresh growth emerges in spring. Remove spent flower stems after flowering and tidy old foliage in late winter. Once established, this variety is easy to maintain and flowers reliably year after year.
