They are quick to flower from seed but temperatures below 65 are required for them to set bud. As a result it may be wise to start the seed early indoors. Provide a well-drained soil that contains much organic matter. Exposure to full sun or partial shade is suggested. The plants grow best in cool climates.
Propagation is by seed.
