6-8 Foot Tall Multi-Flower Double Sunflower

The first flower on this plant is incredible. It will measure between 6-10 inches, typically, and will be very fluffy and absolutely stunning in sunlight. This is one of my favorite sunflowers. Unfortunately, it also doesn't seem to enjoy branching out as much as others, leaving me with one really nice flower and a bunch of smaller short-stemmed flowers.

Sadly, this means it doesn't work well to grow for cut flowers unless you take the first flower. That being said, the flower is long-lived in the garden and is truly beautiful. I would strongly recommend growing this if you enjoy the pictures of the flower, as they are really amazing.
