Mine grows in a hanging basket in bright shade, outdoors year round. The leaves vary from a dark reddish purple to a creamy white. Some remain green with a white border. The little flowers are amazing.

I bought this plant at Lowes or Walmart, and it came with no tag. I was thrilled when I found out it was a hoya. Had one, not this color, years ago and gave it to a friend when I moved. I can't wait to see it flower.

Lovely plant, very low maintenance. Vigorous grower in a hanging basket planter. I moved it outside for the summer and was pleasantly surprised to discover incredible flowers today. It's hanging under a sheltered eave by the back door (facing ESE) with dappled shade from nearby trees. House wrens have made a nest in the plant so I'm watering it carefully now! I'm in Zone 8, Texas Hill Country, blazing heat in the summer. This will be the first summer outside for this plant.
