Wet clay conditions are rarely tolerated by most plants but it seems that blazing star can handle it together with other harsh growing environments.

Blazing star plants provide eye-catching spikes of flowers that are usually purple or white. Rich and fertile soils can be damaging for these plants as they’re adapted to prairie conditions.
