bushiness. I definitely don't want to take it to ground level, unless
that is the advice from this group!

I've never let mine get leggy, so I'm not sure whether you can encourage them to bush out lower down by hacking them back. But certainly in relation to the general thatch at the top I hack mine back pretty hard from time to time and it continues to thrive. Though I have noticed that a smaller-leaf red-flowered one is less vigorous, and can take a couple of years to recover from a hard hacking back.
