Answer: Scarlet runners produce lots of vines from a single plant, but if your little seedlings have lost their leaves, they've probably lost the growing tip. Rather than take a chance, I think I'd replant. Just pop a seed into the ground midway between the original plants. If they all grow, so much the better. If the nibbled plants wither away, you'll barely miss them. By the way, chicken wire hoops or fences are good barriers for bunnies!
