I'm not sure that's possible. You can start new plants by leaf cuttings. Google leaf cuttings Sundews.

They also produce flowers that self sow. One plant can easily produce hundreds+ seeds per flower, with a score of flowers. No need to do anything intricate for them at all!

Ditto in what petiolaris said. You will get so many "weeds" in your pot that you will give up on trying to re-plant them.

well i was reading the savage garden and it said that if you trim of the crown of leaves than new stems will grow from the old stem.
