Acacia elata is my favourite of the genus, at least my favourite of the temperate types. It grows up to about 25m tall, and produces a useful cabinet timber. Also N-fixing of course. Handles frost, but not sure how much, probably only safe in USDA zone 9 up. This is the foliage of juvenile A. elata, with A. dealbata foliage for comparison. Pretty cool tree, highly attractive.
