A.k.a. dotted St. John’s Wort. An adaptable plant with clusters of fairly small yellow flowers. Flowers attract small bees, and the caterpillars of gray hairstreaks feed on the seed pods. Easy to grow, but in the wild is often found in sandy or gravely soil where there is less competition from taller plants. An irritating chemical in the sap means it is solidly deer and rabbit resistant, but may irritate or blister skin.
