Bay Laurel, perennial in zone 6
I recently learned from my elderly Italian neighbor that she leaves her bay laurel in the ground all year 'round. She says it dies down every Winter, but grows back in the Spring. She pointed it out to me, and lo and behold, there it was, tiny, but sending up loads of small branches that were covered in leaves.
I was quite surprised...but it seems to be working for her. She has hers planted in a fairly sheltered area, with my shed behind it, and a permanent cold frame on one side. Maybe that helps? I'm not sure.
Has anyone else heard of treating Bay Laurel this way?
