JB if that marsh Marigold is growing nice this year down there, then go take a piece for your pond, it will do well as long as the weather stays cool. I have had my Marsh Marigold for about 20 years now, and some years it does not grow well when the spring is too hot. If it dies back, it just sort of disapears for a while and then other plants grow and hide it. It is a good year for them cause it was so darn cold last winter. They are easy to grow but you need soft mud to grow them best. You onky need a single leaf and push in the soft mud, keep close to the water level, and it should grow!
