Prefers a cool climate. Flower showy throughout the summer. The yellow flower has a dense tuft of yellow stamens. Foliage benefits from cutting to ground to rejuvinate its look. Can freeze to the ground in colder areas, but rebounds/grows back in the spring. Thrives in poor soil and can be used for soil erosion prevention. Mine grows under lilacs for summer interest in the semi-shaded area.

Creeping St. John's Wort grows throughout my garden. It has pretty yellow flowers, but it is a pain to clear out the dead growth in the spring.
