"Although attractive looking, with several species such as Oxalis tetraphylla and O. adenophylla being grown as ornamental garden or glasshouse plants, some oxalis species can become a real nuisance in the garden. The main problem species are; Oxalis corniculata, O. debilis and O. latifolia." https://www.rhs.org.uk/advice/profile?PID=498
@KathyB I took the pic in the Hervey Bay Botanical Gardens. I have seen it growing in Victoria. I m thinking growers like Mistydown Perrenials, maybe Lamaly, cottage Perrenials. Stephen Ryan Mt Macedon. Good luck. I will also look for you. It is a lovely plant. I'd like some too.
