Comments Can be used as a ground cover if thickly planted. Some varieties will spread very rapidly from seeds, stolons, runners and expansion of the clumps. Blooms sporadically over a long period; peak bloom period is in May. Plants seems to grow better if neglected than if pampered. Seems to benefit from being divided or transplanted at least every other year. Very adaptable (though will not stand full shade), tolerating both flood and drought.
