I've been keeping this plant for over three years now. I use non-terracotta pots that are over 12 inches and window boxes. I've been able to winter it over outside without a problem. The August heat does hit it hard but I like the shiny, bright green contrasting with the brown curls late in the season and it has come back each following spring. It's fun and a nice visual treat between bedding flowers.

I use neem cake in my potting soil at around 6%, I feed once a month with an algae based fertilizer and don't let the soil go completely dry. This year, I'm going to plant it along the garage wall as I've noticed the yard getting a little soggy there. I love this plant for areas with minor drainage issues!

I have no idea what I do to kill this desirable plant. I've had two die on me so far; they were in my pond submerged to pot top. Planted them in the clay based water plant soil in preforated pots and put in shady spots.
They croak in no time. pH? Fish? Everything else is doing well. (almost!) Any ideas? Thanks, dorisb777

I have 'Curly Wurly' (corkscrew rush). Too cool! Grows potted in a water garden, partially shaded by other plants. I can see how it could be invasive in tropical climates, but wonderful plant confined.
