It needs at least 12 hours of light per day to germinate. Press into the medium but do not cover. Keep moist. It's an annual in my zone (5b) but you can grow it in pots and it works well as a houseplant.

That is cute. Where did you get the seed?

I bought seeds last year from dominion seed house. I definitely didn't winter sow, just follow the instructions on the seed package. I may have sowed in slightly moist soil and refridgerated for a few weeks, or else just sowed warm, can't remember.

Anyways, this made a fairly decent pond plant as well, the bottom two inches of the pot was submerged on the pond shelf.

Pleased to report that I have one blade of green showing.Thanks for the tip about hours of light.

The highschool kids here grew this last year. It was 3 months in their greenhouse to get plants that filled a 2.5" pot. I found it a bit messy in the garden so I'm not sure I'd use it there again. A container would have been a better choice.
