Purchased this plant in Oct 2012 and it was lovely. The seller said to keep the soil moist and put it in bright light but not direct sun.

One year ago I bought three of these plants from a seller on eBay. I put two in the ground in a shady area of my yard, and the third went into a pot outside, in another shady area.

The deep, maroon-red leaves and brilliant yellow blossoms make this plant a most sought-after species. An evergreen Oxalis that has brightened windowsills and sunrooms for many years with its richness of colour. A native of Colombia, Venezuela, and Ecuador, it thrives in a bright sunny spot and warm temperatures.

Very rare to own a houseplant with all red leaves, most people love it & ask about this plant.
