Answer: Just like early garden peas, they prefer temperatures in the low sixties or in any case below 70 as well as full sunlight outdoors. You might be able to grow them and get them to bloom if you can keep them both very well lit and also cool -- a cool greenhouse would be ideal. You might try adding supplemental light as well as providing a support for them to climb on. Good luck with your project!
