I had been growing Cyperus alternifolius some time ago. It’s a rewarding plant that can easily withstand drought, neglect and constant wet and boggy conditions. It’s not hardy enough to survive most of our winters outside, so I need to take it inside during the cold months. Last winter, I tried placing my Cyperus plants into deeper water to protect it from freezing. I doubt they froze, but none of them survived.

The other day, a couple of weeks ago, I found large Cyperus alternifolius plants and asked the owner if I can take one that was broken. Received friendly chit-chat and at least ten large Cyperus heads! I was told that these plants return every year even when temperatures in the winter fall slighly below freezing. Hopefully they will be easier to maintain during the winter around here as well. I placed all of them into large jar filled with water and waited. After only 6 days, first shoots already started emerging. I remember when I tried propagating my old Cyperus plants, that started to rot first and then if I was lucky enough, small shoots also poked out.

Sadly I also lost my Cyperus papyrus last winter. It refused to overwinter inside and froze to death outside. If I get my hands on it, I’ll keep it in a bit less humid soil during the winter, I’ve kept mine in water and it sadly turned to mush before the spring arrived.
