Gardeners' Notes:

Recieved from great gand daughter several years back for St Patties Day, and it has been with me ever since, along with its many offsprings. I love it. It adds color to the shade garden as well as sunny areas and pots. When the sun shines through it, it really shows out the red/purple for a nice surprise. The little pink blooms are a bonus. It makes a nice ground cover for bare spots. I know some folks have had trouble with some Oxalis taking over, but these have not been too agressive. I'd like them to be a little more aggressive as many friends and family want some. : )

Very pretty color to leaves, but have trouble with Red Spider Mites when the weather gets dry.

When I first grew this as a houseplant 2 years ago, I thought they were impossible houseplants. Later I learned that they are a type of bulb, and was just dying back naturally as they do! Better as a houseplant here in Michigan; don't always come back in the Spring if left outside in a garden over winter like larger bulbs.

Difficult to remove from my backyard. Easily propagated from tubers. An attractive plant.
