Some Oxalis do, others don't set seed. O. corniculata does set seed abundantly. O. pes-caprae doesn't set seed at all but still manages to multiply abundantly.

This article on O. pes-caprae in our local paper was unusually accurate. http://oaklandtribune.com/Stories/… Liz Shirley Meneice wrote: > Anyone have the answer to this? > Shirley Meneice > -------- Original Message -------- > Subject: Oxalis > Date: Tue, 17 Feb 2004 20:38:02 EST > From: Dpescadera@aol.com > To: samclan@redshift.com > > Dear Shirley, > With all your bulb knowledge, do Oxalis spread by seed (I don't > mean > underground bulbils)?
