Description
Agapanthus Intermedius
Agapanthus Intermedius is a striking deciduous Agapanthus producing large rounded heads of deep bright violet-blue flowers above attractive green strap-shaped foliage. Flowering freely throughout summer, this vigorous variety delivers impressive height, colour and architectural interest to borders, large containers and mixed perennial planting schemes. Its dark flower stems and richly coloured blooms create a dramatic display in sunny gardens.
Agapanthus Intermedius Features
Throughout the flowering season, Agapanthus Intermedius produces impressive flower heads measuring 12–15cm across, carrying up to 150 individual violet-blue florets. Furthermore, the flowers are held on strong dark purple stems that add additional contrast and visual impact. As a result, this variety creates a spectacular focal point in borders and container displays.
The attractive deciduous foliage forms neat clumps of green strap-shaped leaves throughout the growing season. Additionally, the nectar-rich flowers attract bees and other pollinating insects during summer. Consequently, Agapanthus Intermedius provides both ornamental beauty and valuable wildlife benefits.
Growing Agapanthus Intermedius
For best results, plant Agapanthus Intermedius in a sunny position with fertile, moist but well-drained soil. It thrives in borders, raised beds and large decorative containers where its impressive height can be fully appreciated. Moreover, regular watering during dry periods 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 robust variety flowers reliably year after year.
