creeping thyme?

Also, try Ice Plant and Baby Sun Rose.

Thanks for the suggestions.

Hmmm - my coneflowers get so thick I can't under plant them. In a walking area I would try the creeping thymes or roman chamomile. For very low/no trafic areas possibly horehound, alyssum, forget-me-nots, sedums, or creeping rosemary too (?).

I tend to mix other tall or vining plants with my coneflowers; coreopsis, cosmos, morning glory/moon flower, annual poppies, and passion flowers.

Purple verbena - although it, like much of the others won't care too much for foot traffic.... maybe you could put some stepping stones down?

HTH

Ditto on suggesting the stones. There's not too much here that can take both the heat and the walking.
