Cup Flower gets its common name from the cup- shaped flowers it freely produces for much of the growing season. Provide a growing area with a well-drained soil and exposure to full sun or partial shade. The plant may also be used as a potted plant.
Propagation is by seed or cuttings.
The plant is slow to flower from seed. Start seed indoors about 10 weeks before they are to be planted in the garden. Germination can take about 3 weeks at 70 degrees. Wayside Gardens 1999. This information is for educational purposes only.
