So so. 2016-08-31
Ten seeds and only 2 plants grew. 100's of seeds harvested but they all turned hollow so are not viable for planting again. What's the point of sunflower's if you can't harvest and replant?! Achieved only 8ft and 6 ft from the 2 plants that did grow.

Despite the awful weather this year all the seeds germinated but they are not as tall as last year only eight feet and the flower heads not as large.Even so they are imposing flowers and the bees love them!
Flowers not as large 2011-08-22
Full germination and plants were a variety of heights ,the shortest being 3 meters the tallest almost 6 meters I used a nearby conifer as a post to tie the stem to. A great source of interest to my neighbours young lad. I have already bought the seeds for next year. I will try for larger flowers next year .
