The petals are all fused together, forming a bowl around the yellow center.

Fairly pest-free and low maintenance, add this charming plant to the landscape and you will be rewarded with abundant butterflies. Creating a graceful visual impact in the garden, it is perfect at the back of sunny borders.

  • Grows up to 3-4 ft. tall (90-120 cm) and 20 in. wide (50 cm).
  • Performs best in full sun, in average, moist, well-drained soils.
  • Ideal addition to beds and borders, containers, cottage gardens, prairies and meadows and cutting gardens.
