If you want to optimise the ecological value of your garden you should only
plant local native species. The Mt Morgan Wattle, a native of Queensland,
has become a weed in the Clarence Valley as has the dreaded Cadagi, a north
Queensland native. You don't need exotics or grafted natives as they don't
provide the natural habitat that local natives provide. I know people will
plant them but that is their choice. It isn't the best ecological choice.
Yes call me a purist but I contend that there is no better way to be when
considering ecological gardens. Non-local Grevilleas and bottlebrush often
attract the larger birds that displace the small passerines, just as feeding
often does.

Penny you need to be wary about saying "just plant natives" - many wattles
are far worse weeds in Australia than camellias and roses, for instance.
Most eucalypts, wattles, hakeas and grevilleas have some level of risk. The
best advice is a mixture of local natives and habitat species that can be
native or exotic BUT are researched for their weed potential. Anything
native that is grafted is generally good as its seed progeny are unlikely to
survive (a good thing!)
