Sorry Lorn. I took Joe's statement that they are "supposedly not very hardy" in respects to cold tolerance not heat. Most things I have read in regards to hardiness refer to the lowest temperatures a plant will survive at, not the highest. Though we certainly can't match the heat of Texas there have been plenty of days over 100F in my area and my gold bands haven't suffered any damage from it yet. I've found light shade, mulch and a little extra moisture go a long way in reducing heat stress.
