I grew esclepias 'Monkey Balls or Fur Balls' plant this year and it has been a blast to watch. You can read about it on my blog. Search the sidebar for Monkey Balls.
The plant grows beautiful clusters of hanging flowers and then forms hairy balls--which are the seed pods of course. Monarch butterflies love them and at the moment, I have 10 caterpillars on each plant. Fascinating plant.
