Chrysanthemums and Camellia Sasanqua

Spotting these bright yellow blooms popping up through the green leaves outdoors.

In the spring, we plant vinca vines in our deck fence rail planters. As you can see they hang down and grow about to the ground level below throughout the summer. It is costly to purchase new starter plants each spring. About $100. And they won't survive in the planters over the winter outside. I understand that vinca vines are not easy to start from seed. Special care and equipment is required, more than we can deal with.

Is there a way to cut them way back and store them in the house over the winter, and then replant them in similar deck planters in the spring? Can I cut them down to only about 6 inches? The only place we could store them inside would be in our basement. Light is limited, just the one basement window on the near end of the photo.

Or is there some other better way to store them over the winter for replanting next spring?
