She will take both foliage and flowers. And there are huge, medium size, and small boulders. She is willing to irrigate if it doesn't rain. There is lots of space between some rocks, very little between some. I'm not sure how deep the soil goes; I suspect it varies, deeper in places, shallower in places.
I didn't think about bulbs, I like that, I think she will, too. I really like the species tulips, I've grown them and love them. I'll check out the daphnes. Now about salvias, we can and do grow many different ones here; the ones that seem to do the best are the microphyllas, do they do well in dry conditions? I have a hot lips that is huge; I whack it back twice a year, but I find it to likes to be watered on a regular basis. Agastaches do rather meh here, perhaps they need hotter and dryer? I'm really sorry I messed up your name! Thanks for all your help, I'll do some more research.
