Description

Agapanthus umbellatus Albus, also known as Agapanthus africanus var. Album, is a majestic herbaceous perennial with rhizomatous growth. In summer, it offers large umbels of white flowers carried well above a semi-evergreen to evergreen ribbon-like foliage, depending on the climate. This highly graphic plant, although not very hardy, will thrive on a sunny terrace or in borders under mild climates, in well-drained soil with a tendency towards acidity.

 

Originally from South Africa, Agapanthus umbellatus should not be confused with Agapanthus praecox, even though these two species naturally hybridize in the wild or in our gardens. Agapanthus umbellatus Album is a rare form of this plant that grows from the Cape Peninsula to Swellendam, at low altitudes, in mountainous areas, between rocky outcrops, and on sandy soils with a tendency towards acidity. It develops from a rootstock with fleshy rhizomes, forming a dense clump of linear, shiny green foliage, at least 60 cm (23.6 in) in diameter, expanding over time. The flowering occurs in summer, from June-July to September. Sturdy stems, 80 cm (31.5 in) to 1 m (3.3 ft) tall, bear at their tips large hemispherical umbels, 15 cm (5.9 in) in diameter, composed of small campanulate snow-white flowers carried by long peduncles. In South Africa, it is often subjected to fires that destroy the vegetation of the Fynbos, and seems to flower more abundantly when it has experienced fire.

 

Agapanthus umbellatus 'Albus' is magnificent in the garden with its large inflorescences that stand out from a well-filled clump. The pure white colour of the flowers and their abundance will add an elegant touch to your borders. Unfortunately, it is semi-hardy and will disappear below -6/-8°C, which is why it should be given a protected, south-facing location, and an ample mulch should be applied at its base. Whether in borders, edging, large rockeries, pots, or containers, this Agapanthus is suitable for a wide range of uses. It is particularly well-suited to mild coastal climates.

It is beautiful when combined with other mauve or blue varieties in a minimalist garden style. It is also very decorative in exotic-themed borders with Kniphofias, Hemerocallis, and Phlomis fruticosa. In mild climates, it can rebloom multiple times.  Moderately hardy, agapanthus should be grown in pots north of the Loire. It is advisable to mulch them in case of severe frost. They prefer a rich and moist but well-drained soil.

Planting and care

Plant Agapanthus clumps by covering them with at least 5 to 10 cm (3.9 in) of good soil so that they are more resistant to cold. It is essential to plant them in spring and mulch them in winter. For pot cultivation, use 5 young plants for a 24 cm (9.4 in) pot and shelter your pots in winter. They prefer a rich and moist but well-drained soil, enriched with sand. Water them regularly during the growth period (twice a week). However, avoid watering them afterwards. They are sensitive to winter moisture excess. This variety particularly thrives in rockeries and containers. Use a well-drained sandy mix, slightly acidic. This plant seems to prefer shallow containers and will flower abundantly if regularly fed with slow-release fertiliser.
