PERENNIALS
Callirhoe involucrate (purple wine cups)

Low-growing mounds of cut-leaves are covered with large, purple, cup-shaped flowers all summer. Can self-seed and spread once established. Grows in hideous clay soil, and heat and drought only slow its growth slightly! An excellent border plant and groundcover. Zone 4
Caltha palustrus (cowslip, marsh marigold)

Bright yellow flowers cover this wetland native over glossy green, round leaves in late spring. Grows to 2' tall and goes dormant in the heat of the summer. Zone 3
Calylophus lavandulifolia (calylophus)

Very large yellow flowers fade to apricot. This native of the plains produces blooms most of the summer when planted in a sunny, well-drained site. Gray-green foliage is needle-like and fine. Grows 1-2' tall in full sun. Zone 4
Campsis radicans (trumpet vine)

Old fashioned orange trumpet-shaped flowers in mid summer on a climbing vine with deeply cut, dark green foliage. Large pods add interest and texture in early fall. Attracts hummingbirds! Zone 3
Celastrus scandens (American bittersweet)

Vigorous, twining native vine grows to 20' or more with glossy green leaves that turn brilliant yellow in fall. In September, female plants are covered with showy pendants of yellow-orange seed clusters, splitting open to reveal brilliant red centers. Great for everlasting bouquets. Our plants have multiple cuttings in every pot to ensure both male and female vines are present to produce seed clusters! Zone 4
