WardDas said:I have had problems with cana and aurantiaca in really hot and dry conditions. For they just don't survive long in those conditions, conditions where Salvia greggii & microphylla experience no problems. This was entirely unexpected and it has led me to give up growing them. The only reliably hardy Agastache for me in dry sandy never watered conditions is rupestris and hybrids of rupestris. Cana and aurantiaca seem to only go as annuals or very short lived perennials.

We've found too that most of the common drought resistant (read this as Southwestern native species) Agastache are short lived. The possible hybrid 'Sining', a patented variety developed by Plant Select in Denver and sold as Agastache cana 'Sonoran Sunset'. Hold up very well in all sorts of conditions. And is less floppy than most of this sort. Our customers tell us that in their native conditions these Southwestern species are fairly reliable. But give them some humidity and they long for the desert.
