Roots: substantial tap root that gives rise to many laterals. (will re-shoot from any root stock left in ground). Ecology One of <strong>the</strong> most significant threats to <strong>the</strong> last remnants of Cumberland Plain woodlands in <strong>the</strong> Sydney Basin; threatens fur<strong>the</strong>r ecosystems in Sydney North. Forms dense mono-cultures beneath which no o<strong>the</strong>r vegetation remains. Dispersal Water, animals (foxes, rats & birds), humans, contaminated soil (earthmoving equipment, cars etc) and garden refuse dumping. Control HAND: dig/pull juvenile plants; bag and dispose of all berries.. CHEMICAL: cut or scrape and paint; foliar spray. African Olive European Olive Native look-a-like Plum Pine Podocarpus elatus.

Common name: Agapanthus Latin name: Agapanthus praecox ssp. orientalis FAMILY: ALLIACEAE ORIGIN: South Africa Noxious Weed Category: n/a Description Habit:vigorous tufted perennial. Leaves: Large thick glossy-green, strap-like leaves to 50cm. Flowers: Large globular flower heads in blue, mauve or white flowering in summer. Fruit: each flower produces many small black hard coated seeds which are held in a three-sided capsule. Roots: robust fleshy. Ecology Drought and shade tolerant, but will live in full sun and full shade. Clumps spread vegetatively and outcompete native ground covers (including seedlings of canopy trees, shrubs and vines). A water-hogging weed capable of killing mature trees presumably through dehydration. Dispersal Seed spread by wind and water, and people transporting trailers with de-headed flowers to <strong>the</strong> tip. Vegetative once established often through garden dumping. Control HAND: only practical for small clumps of <strong>the</strong> plant. When digging ensure that all <strong>the</strong> root material is removed. Dispose of contaminated soil or monitor for regrowth. It is important to pull out all roots from beneath <strong>the</strong> soil. Alternatively, cut <strong>the</strong> flower heads off before seeding to help prevent spreading. Brush cutting or mowing must be done regularly. SPRAY: Cut leaves off, brush-cut or mow to stimulate new growth, <strong>the</strong>n spray new growth with a registered herbicide. The area should be monitored for regeneration.
