These weeds are known to be problematic in other regions. Some of these species may be considered ‘sleeper weeds’ – plants that are present in an area in small numbers and have the potential, with a slight change of conditions, to spread widely and have significant impacts. Climate change could be the driver of such weed spread and therefore, now, more than ever, it is advisable to keep these weeds on your radar and source further information to enable accurate identification and control. This is by no means a comprehensive list of potential problem weeds, however it does cover a broad range of weeds including all those from the ACT Pest Plants List 2005 and the relevant sections of the ‘Regional Weed Strategy – Murrumbidgee Catchment’ (2007).

(1)Other details: This plant is attractive to bees, butterflies and/or birds (2)Very useful for attracting honey eaters. (3)Note also that quite a few Grevilleas that are primarily bird-pollinated (and hence carry a heavy nectar load) are also, for that reason, heavily visited by introduced honey-bees (Apis mellifera). This often includes G. rosmarinifolia. It is likely that these bees are functioning as more-or-less effective pollinators. (4)Excellent habitat. Dense prickly foliage excellent refuge for small birds, including finches and wrens. Nectar-rich flowers attract native birds, moths, butterflies and other insects.

(1)Fruit/seed: Hairy capsule 8–11 mm long, with 1–2 seed released at maturity. [no evidence that fruits are ingested] (2)Monitor closely as seeds shed soon after maturity. Follicles turn from green to brown at maturity. Ensure collection by securing nylon stockings or paper bags to fruiting branches after flowering. Usually only small portion of flowers set seed.
