The method I use is quicker and more dependable. Mix a handful of seeds with some moist (not wet) sphagnum moss, in a large ziploc bag. (Soak the moss, then wring out the water.) Zip up the bag containing seeds and moss, and leave it somewhere warm. (Our early autumn days are pretty warm here on the gulf coast, so I actually leave mine outside but not in direct sun.) Within a few weeks you will see the tap roots have formed. (Its like looking in a terrarium.)

Once they have germinated, remove the seeds and plant them. I put them all together in an extra pot or two, tap root down of course and seed planted just even with the the soil level. After they have sprouted leaves and grown for a few months they can be separated into separate liner pots. For soil mix, use something very light -- such as sand and perlite, or sand and a store bought planting mix which has a lot of bark. (Don't use potting mix which is dense and mushy.) Mix in the left over sphagnum moss from the ziploc bag.

Good luck, but be patient -- it takes a few years for the plant to reach blooming size. And you never know what you may get, each seed is a hybrid.
