Oxalis deppei 'Iron Cross' (Iron Cross Oxalis) - This bulb, sometimes grown for its edible tubers, is grown by most gardeners for its attractive leaves that are composed of 4 large leaflets that have a strong dark purplish band at their bases, forming a cross-like design in the center of the leaf. The leaves that stand up 6 to 12 inches tall are otherwise a bright green that contrast well with this cross and in the summer into fall appear bright pink flowers. Plant in sun or part shade and give occasional to regular irrigation. This plant can remain hardy in frost free gardens and is hardy to around 10 F as a dormant bulb. This Mexican native was introduced into cultivation during the heyday of plant collecting in Victorian times and has proven itself garden worthy and non-invasive. The foliage, containing the poisonous Oxaloacetate, has a lemony taste that when used with moderation is not considered harmful and is often in foods cooked and fresh. Oxalis deppei is synonomized by some authors with Oxalis tetraphylla while others insist they are distinctly different plants. Until we get verifiable information to do differently we will continue to list it as Oxalis deppei, the name we originally received with it..  This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Oxalis deppei 'Iron Cross'.
