I grow Brunnera macrophylla in a container and I am surprised it is enduring here. I guess our winters are mild enough for it. But it does hate the heat, so have to be always in shade, and have to give it frequent watering, since it is just too bone dry here. During summer it is not as vigorous since we go into the triple digit dry heat. It sure enjoys the mid 50's to low 70's nicely. Come mid fall to winter, it comes back better, I get the blooms in early Spring. The lowest temp we get is around 20 to 21F just for a few nights in winter.
I lost Heucheras..I think it got fried by our heat and got a bit underwatered. I may try it again one day, but not this year. With our ongoing drought, not going to add any new plants, just going to maintain what I have.
