Agapanthus campanulatus Rosewarne

Agapanthus campanulatus 'Rosewarne' is a recent variety, rare in cultivation, obtained in England at the experimental horticultural station of Rosewarne. It stands out for its large development: this variety grows over 1 metre (3 feet) tall with very large umbels reaching sometimes 20cm (8in) in diameter. While these inflorescences display a particularly vibrant sky blue colour from a distance, they owe it to each small flower striped with white and dark blue that composes them. This variety is not only of beautiful stature, it is also relatively hardy and develops a beautiful evergreen foliage of a greyish green. It is a majestic plant, with obvious graphic appeal, and can be grown outdoors in a temperate climate.

Native, like all Agapanthus, to South Africa, Agapanthus campanulatus is native to Natal. 'Rosewarne' is a particularly vigorous hybrid form of this plant with blue flowers that grows at low altitudes in wet meadows. It grows from a stump with fleshy rhizomes, forming a dense clump of linear, ribbon-like foliage, at least 50cm (20in) in diameter, expanding over time. Each leaf, usually evergreen, can reach 40cm (16in) in length. Flowering takes place in summer, from June-July to September. Solid stems, 1 to 1.20 metres (3 to 4 feet) tall, bear large spherical umbels, 15-20cm (6-8in) in diameter, composed of deep blue flower buds that open into small campanulate flowers striped with white and deep blue, carried by long peduncles. In cold climates, the foliage may disappear in winter. If the stump is well protected by a thick mulch that will isolate it from excess moisture, the foliage will reappear in spring.

Agapanthus campanulatus 'Roseware' is magnificent in the garden with its large, vivid blue inflorescences that stand out from a well-filled clump. The unique colour of the flowers and their abundance will bring an elegant and exotic touch to your flower beds, alongside the white-flowered form. Relatively hardy, it can withstand temperatures around -8°C (17.6°F) without weakening. It can be planted outdoors in Mediterranean areas or along the Atlantic coast. In colder regions, it should be given a very protected and south-facing location, and a thick mulch should be placed at its base. It is particularly suited to coastal climates.

We deliver them as 2/3 eye stumps. Over time, they will form stronger and stronger clumps.
