Bulbous Plants – Agapanthus (Blue African Lily)
Agapanthus plants are native to South Africa and were introduced into Europe in the seventeenth century. The most commonly grown varieties are the Headbourne hybrids, which are available in an array of blue shades. White varieties can also be grown but don’t have the same impact as the deep blues.
The round balls of the agapanthus blooms provide a late summer spectacle. The intense, blue flowers can provide a focal point in a border or a tub, or they will mix well with a range of other plants. Deciduous Agapanthus are generally hardier than the evergreen ones but both will tolerate a light frost.
Agapanthus love full sun but they have been successfully grown in light shade. Headbourne hybrids are hardy, but some of the other species and hybrids will also come through most winters. The problem is winter wet as much as cold. Covering the plants with a sheet of glass to keep them reasonably dry, while allowing air to circulate to prevent condensation, will help.
These plants require little attention other than to tidy up the rotting leaves and flower stems during the early winter. They will rarely need staking. If you don’t mind sacrificing a few stems, they make good cut flowers from the house.
Growing Requirements
Soil
These plants like a moist, free-draining soil, but will grow well in a dry soil that has had organic material added. They thrive in deep, fertile soils but will tolerate quite poor soil.
Size
Agapanthus can reach a height of 3ft (90cm) with a spread of around 2ft (60cm).
Propagation
Dividing existing plants in spring is the easiest way to increase them. This must be done carefully, as the roots are brittle and resent being disturbed. They are best planted out in spring and should be placed about 18in (45cm) apart.
Family: Agapanthaceae
