If you know nothing else about native plants of Houston (and Texas in general) .. the take away knowledge nugget for you is “echinacea”.
This is an absurdly tough flowering plant genus that butterflies love to spoil with their lofty love whispers. And they are a lazy gardener’s dream plant. No time to tend the garden? Astros in the playoffs and better things to do? That’s not really an issue for crazy echinacea purpurea. In fact it will probably grow another 4 inches by half time .. water or not.
