Inspired by your previous pictures of your winter-grown Ipomoea's I have started some seeds on the doorsteps of winter.

Its supposedly I. tuberosa and I. muricata - and flowers are presumably many sun-filled hours away... hope to see some before next autumn :-)

Carsten, good luck with those species, I do not recall growing them before. It will be exciting to watch them grow. Feel free to add comments and photos of your plants' progress.

I stored the seeds in plastic bags into which I placed a silica desiccant packet to keep the relative humidity low inside of the packet. I store seeds in cool room temperature, not the refrigerator.
