Thank you Evan. I love this hebe. It has not bloomed for me, just has awesome foliage.
I know it has come through single digit temps for me. I think the main thing is to give it really good draining soil. That can really be a problem for us in the PNW. It has been here for about 5 years now. Everything I ready about zone hardiness says zone 8. It sure wouldn't hurt to give it a try.
