You know you haven’t been hiking or botanizing out in the desert or grassland enough when you look to the roadsides for interesting plants, but I’ll tell you what, if you keep your eyes open you’ll find some cool stuff mixed in with the weedy annuals, like the whiteball acacia I mention or milkweeds or coyote gourd or clematis.

Both camphor-weed (Heterotheca subaxillaris) and lizard tail (Oenothera curtiflora, the former Gaura parviflora) are native annuals and have a wide range across the United States.
