That should work, depending on the amount of sun they get. 'Blackie' seems to be darkest in a good amount of sun and sometimes the oxalis wants less but you can see how it goes. You could also consider mixing and matching and also getting Oxalis regnellii 'Atropurpurea' and Ipomoea batatas 'Marguerite' to give the opposite type of coloration, with the purple-leafed oxalis and lime green sweet potato vine.

Hi Patwood, I am very very interested in trading with you for your Qxalis. I love this plant! I have no bulbs to exchange with you though. I do have many plants that I can divide and share with you and also have many many unusual seeds. Please let me know either way at the above email address because I always forget where I am here at GW,lol. I forget where I've posted things! Thanks, Debra

I have Oxalis regnelli as well as triangularis and Iron cross. I would like to trade for other Oxalis or other bulbs (see my wants list), if you have any. Susan

I have several shady plants for trade...Boston Fern, breathless blush euphorbia and serveral others ...PLMK
