Dear all, It is very hard to overcome the prejudice against Oxalis. I offer about 15 species and forms and try to be very careful not to offer species which can spread dangerously. On the blacklist are O pes carpea, caprina. Oxalis obtusa (which came of M vassar's collection (via Mary Sue) about 8 years ago, can spread quickly (as Jane said) but is controllable. Making uniform one colour collection of O obtusa strains is a very time consuming and tedious job! I recommend the smaller species as excellent pot plant, which give colour to the garden from November till early April.
