I have a section of my garden that never gets watered. The plants back there have been picked off drought tolerant lists. I have several varieties of yarrow, liatris, also several kinds of blanket flowers, hyssop, coreopsis, echinacea, lavender, and day-lilies. I might have missed a few, but that is basically it.
I bought a burgundy blanket flower last season that I can’t find. It was a tall stringy plant, so am not surprised. Guess I can’t say that one is thriving! The plant below is one grown from a packet of wildflower seeds, many years ago.
