Native plants for dry sites

Plants on this list do well in locations that are consistently dry and well drained. In fact, they may struggle in average soil moisture conditions.

That being said, in my experience, dry conditions are the most brutal for plants to combat. We often have years with 20-30 day stretches of no rain in August and/or October. That's a lot to ask a plant to handle. I combat this in my gardens with 4-6" layers of leaf mulch every year in the spring. And when I know the conditions are brutal, I do water. But it's not often. 

So definitely chose the right plants. But also, give them a fighting chance for survival with a lot of mulch to keep that moisture in the soil (bonus: mulch blocks weeds, keeping your plantings lower maintenance).
