I bought this little tree by accident at a native plant sale because it has been mislabeled as Acacia occidentalis. I was going to return it, but the tree's attractive shape, spininess, and long distance back to the nursery made me change my mind.

The common name is Roundflower acacia or Roemer acacia. (Catclaw acacia = Acacia gregii.) This little tree has adapted so well it's turned into a medium-sized tree, more than doubling its size after less than 8 months in the ground.

The new growth is red and the unopened flowers look like little unripe raspberries. Its lightly fragrant flowers attract all kinds of native bees, but few honeybees.

The branches tend to grow out from the end; as a result our tree has developed lots of arching branches full of curved hooks that snag clothing. Don't plant this one near walkways. On the other hand, it would make a good barrier for that reason.
