Agapanthus Information
Grown for their showy flower displays, Agapanthus would benefit from additional watering in summer times. These are marginal plants and can be found around the edges of ponds and lakes in their native lands
Whilst hardy these plants are best protected from the harsh winters using a cloche or frost fleece.
They can be grown from seed, but most commonly Agapanthus is propagated from root cuttings. This can be done in late autumn. Lift and divide over grown clumps every 4 years. At this point you can break off sections of root and propagate them indoors in pots or seed trays
