Can you overwinter Cobaea?
Cobaea will behave as a perennial if kept indoors over winter at about 7°C (45°F). Outdoor plants may survive a very mild winter, in a very sheltered position with some protection, but Cobea grows quickly enough to be considered an annual if conditions don’t favour it surviving the winter.

Should I pinch out Cobaea?
It’s best to support the plant, which produces tendrils to cling onto the support. They like full sun and well-drained soil. You can help the vine by training it onto a trellis or support as it grows. Pinching out the tip of the vine will make it grow lateral shoots.
