I have some in zone 8 and they winter over, bloom for a long time. No care except deadheading after blooms go, no pests. They do well in partial sun, and hummingbirds visit them. Pretty foliage for a shady spot groundcover.

The water use of (AI) datacenters is often discussed purely in terms of evaporative cooling for the datacenters themselves (which can be replaced with zero-water closed-loop or advanced air cooling with sufficient capex).

But it turns out most datacenter water use is indirect by way of the grid and water-cooled thermal electric generation, like coal and traditional nuclear, which evaporate large quantities of water
