Agapanthus praecox ssp orientalis
- Hardy perennial lily from South Africa. Grows in thick clumps, tough, hardy, likes full sun, grows in almost any soil, almost anywhere. Also called Lily of the Nile.
- Leaves are thick, succulent, dark glossy green and strap-like, to 50cm long, and poisonous. There is a weedy miniature or dwarf variety, and a number of cultivars, which should also be closely watched for invasive qualities.
- Large, rounded heads of massed tubular flowers, blue or white, top a strong thick stem, to 1.2m tall, in summer.
- Numerous small black shiny seeds are produced in a 5cm three-sided capsule, end of summer into autumn.
- Roots are fleshy, crowded, strong and tenacious.
The underground structure (rhizome, poisonous) forms large continually extending clumps, and seed washes down waterways. Agapanthus is also frequently dumped on bushland edges.
Impact on Bushland
Spreads rapidly down drainage lines, but will also grow in dry areas. Dense clumping roots displace all other vegetation.
Throughout the Blue Mountains.
Spiny-headed Mat Rush (Lomandra longifolia)
local native flax lilies (Dianella species)
Saw-sedges (Gahnia species)
Pride of Madeira (Echium fastuosum)
Cut the flower heads before the seeds form, while they are still green and sappy.
Dig out clumps with a mattock. Try to get most of the roots.
Pull seedlings by hand from moist soil when very small.
Does not respond well to herbicide, but can be treated by cut and paint: crown, and apply herbicide instantly, before sap bubbles out.
Follow-up weeding of seedlings and shoots from rhizomes will be necessary.
