Below, Salvia pratensis 'Pink Delight'. Import.
Gaura, the white flowers. Texas! The pink on the left is bad. Three years ago I'm afraid I loved Lythrum, purple loosestrife (even though it is shocking pink). It invades wetlands and pushes out the natives, changing all sorts of things in the food chain. It's pretty, but very bad. So I learn, I learn.
Dust to dust.
Miscanthus is from Asia, so is Pennesitum - both grasses. Miscanthus is potentially invasive, though the species is considered less horrible. But the abundant Panicum (switchgrass, wand panic grass) is a true prairie local.
