Yes, as said previously cape weed and pattersons curse, but also plenty of other ground plants, some wattles and the broad leaf peppermint looks good for this spring around the Flowerdale hills that didn't burn too hot. That is at the break, o, day end of the valley.
Yes land prices have started to climb out this way as melbourne expands. If you want to get some acres there are not many places left any where around melbourne. Certainly non as beautiful as around those flowerdale hills. Good luck, don't leave it too long as the prices won't wait for you.
