Ok, I have seen a field of these before as well. My question is, because of the sheer density of plants, do you THINK that some can survive the winter, and essentially making it an ever lasting field?
Also, I guess the stalks are good for cows and gosts, so we feed depleted stalks for them.
You would be surprised, on what an entire ecosystem can look like on a single plant, beauty...o by the way, I'm going for the world record sunflower this year (first year trying)
I'll have videos up on my youtube channel
