Where to start in Harris County
If you have only one spot to fill, sun all day is where Harris County gives you the most rated choice (253 plants), and Bedstraw St. Johnswort (Hypericum galioides) is the easiest start on that list. Never watered is the hard one here: 111 rated plants, so for that spot it is worth asking a local native-plant society about the 748 unrated natives too.
