Sow seed in a baggy at 70*F. Approximately 34% of the seed could germinate between 7 - 11 days. This seed needs light in order to germinate.

In the baggy method, a relatively sturdy paper like coffee filter paper is moistened and then wrung until barely damp.
Place the seed in the center of the barely damp filter and pull 1/3 up over the seed, then the top 1/3 down over the seed and then fold the ends over the center. Place that arrangement along with a water-proof label (that can continue to be used later) inside a baggy and transplant as soon as they germinate. Some gardeners hang the baggies vertically.

To keep the filter paper from drying out, it may be necessary to occassionally spritz it from time to time with just enough spray of water to dampen it. Don't let germinating roots go too long before potting up or they may get tangled up in the filter paper.
