Not easily - best method is to sow seed and keep in a coldframe over winter and pot on following spring. Otherwise its trying very carefully to separate a clump if it has more than one tap root, or taking root cuttings.

If you go to a branch of '99p Store' at the moment they have 3 roots for ....99p (how surprising!!). They are in plastic bags with cardboard picture attached. These should flower this summer and would be the quickest way to get one...or 3!

thanks, volunteer I did that look a bit strange, hope i got them the right way up
