[Grah the great]

Hi everyone! In late March of this year, I will be setting up a greenhouse on my back patio and putting a 15 gallon water garden (with a deicer running at night) in it to serve as a heatsink. Naturally, I am looking for pond plants that would thrive in those cool spring months (and fall months) when nighttime temps will drop into the high 30's. I have already identified water hawthorn (Aponogeton distachyos) as an option, but are there any others that will grow well during those cooler months? During late spring-later summer, the deicer will be replaced by an aquarium heater keeping nightime temps in the 60's. Thanks
