Plant Information

Common butterfly weed native to the central parts of the continent makes a striking long blooming perennial in our gardens.

Fantastic plant for all pollinators. Remarkably showy perennial for very well drained soil- try a slope and deep but infrequent irrigation or add a few handfuls of pumice to the planting hole.
