PLACEMENT & CULTIVATION
Cup and saucer is an elegant plant for trellis and arbors with beautiful leaves and stems and unique flowers. Plant in a warm, protected southern exposure in short-season gardens; some afternoon shade is tolerated in hot climates. Wait to plant until the night temperatures have warmed, generally 2-3 weeks after frost danger. As the plant matures, the tendrils cling to any rough surface and climb quite tall; pinching to control size is recommended. The flowers bloom starting in midsummer and continuing into late fall and make beautiful cut flowers. If growing in containers, select a large container that drains well and use a rich, well-draining potting mix.
