Yes, that should be plenty of room for them to flourish. I would only plant one per container. Make sure you have drainage in your planters.
Yes. You may have to start the training, but they catch on pretty quickly.
No, it is not recommended to be planted in the winter
No, it is not edible
Hi NUNZIO. Thank you for your question. Whether the Star Jasmine will be available in your store will depend on your planting zone. The Hardiness zone for this plant are zones 7 to 10. Please let us know if we can be of further assistance. Rick_HD_OC
No, it is not since it normally blooms in summer or spring.
No, this will not survive in Zone 5B.
I put the jasmine plant I bought in an east facing window, and was careful to keep it wet, but it still started loosing leaves. My wife moved it to a south facing window in a different room that was slightly warmer and it started growing long vines and flowers. So I think the added afternoon sun might have helped, but I'm still not entirely sure why there was such a difference. Maybe it took a week or so to recover from being shipped??
