Every October the meadow trail at the Houston Arboretum and Nature Center blooms with swamp sunflowers. Last October, I visited the Arboretum for the first time, and coincidentally it was during the blooming period. This October I went purposely to get photos of the meadow (and some photos of me!)
Swamp sunflowers are a variation of the sunflower, and they grow in all coastal, wet areas, from the gulf to the eastern coast. This makes sense, because this meadow is right next to a pond.
