    The tough, erect stems soar upwards in spring and are covered by large leaves that fuse together at their bases to form a sort of "cup" (hence the common name). This is a very attractive feature after rain as they often hold glistening balls of water. In mid summer clusters of bright yellow daisies crown the plant. These are airy enough not to dominate the surrounding planting, even though they can reach 2.5m tall. A native of tall grass prairies, meadows, thickets and stream peripheries in North America, this plant has a deep and extensive root system which makes transplanting difficult, so make sure you have the right spot for it. It will attract birds and butterflies to the garden and will exude an aromatic resin if you crush the leaves and stems

  • Garden care: Divide congested plants in spring.
