When the seed pods or capsules turn brown, cut off individual pods and leave at room temperature until pod is dry. The pod can then be opened to collect the fine, dust-like seeds. The entire flower stalk may be cut off and put in a paper bag until the seeds ripen. The seeds may be stored dry in a plastic bag in the refrigerator.

Sow the seeds indoors in cells or flats filled with seed germinating mix, or outside after danger of frost. Keep the mix moist. Seeds should germinate in 2 weeks. If seeds were sown in a flat, when the seedlings are big enough to handle they can be separated and planted in individual peat pots. The plants should bloom the first year.
