I've been growing these for a couple years, they grow 6-8 ' tall in zone 5 Minnesota and fall over and cover quite an area. Blooms right next to beebalm in our garden, and is visited about as often, more by the mason bees that the giant bumblebees or hummingbird moths.
Forms a very dense mat-like base which can be harvested and eaten. We snap off the shoots and add to salad. Very pleasant fall asparagus. Unique flavor.
4/5 stars.
