These attractive pot plants grow around 6 inches tall (13 - 15cm), they do best in bright diffused sun in moist soils that are not wet. They are strong robust plants with large flowers. They can also be planted outdoors in the garden or used in combination containers. These are early flowering, start in late winter for late spring flowering or in late summer for holiday flowering.
Surface sow seeds and use F 60-70, germination is spread out over a month or so. Might be helpful to seal up in a plastic bag. If no germination in 4 weeks move to 30-39F for five weeks. Then back to 65F.
