I grow Phygelius. I've got several different ones, including Devil's Tears (orange), Sunshine (yellow with yellow foliage) and Sensation (deep pink). In my garden, they seem to be hardy, and very tough. The frost knocks them about over the winter (except Sensation which is in a pot on the south-facing patio, which is well protected, so it stays evergreen), but I just hack them back to the ground in spring and they sprout up again, no problem. In fact, Devil's Tears is a complete thug! It runs underground and comes up in silly places like the middle of another plant! I often dig up stems which have rooted, and pot them up for sale at my Flower Club plant stall.
