I haven't seen Monarchs here in north central Texas since the drought settled in. Milkweed, which is normally seen growing, also is scarce now with the drought. I would have thought, with the long taproot, it would have been more drought tolerant than it seems to be. Because of the lack of bloom, bees and butterflies of any kind aren't plentiful. The bird bath attracts bees as much as it does birds, but not butterflies. I'm growing the first Mandevilla I've ever tried and discovered it is a milk weed. Anyone know if Monarchs eat it?
