Answer
Hi John,
Thanx for your question.  Hopefully, your plant is not a hybrid.  If you are taking seeds from a hybrid plant, the results will be extremely variable and there would be no guarantee as to an exact copy of what the parent plant is.  Sometimes this will result in a superior plant but more often than not, the plants will be substandard.  With that said, if your plant is not a hybrid, you should be able to get new plants from the seeds you harvest from your plant.  Wait until they are fully ripe. These seeds can be planted barely covered with soil in average potting soil and kept moist but not soggy and warm.  Germination should take place in 1-2 weeks but can be rather sporadic and take up to a year for some.  Keep track of how many seeds you plant and then you'll have an idea of how many you're waiting on and whether or not you want to wait on the stragglers.  The seedlings will come up looking like grass.  When they become large enough to handle, put them in separate pots.  Be careful as their roots can get long and they are brittle and you don't want to break them.  Leave the plant in the pot until it is large enough to plant in the desired, full-sun location.  I hope this helps.
