Giant sunflowers defying heavy traffic

Sunflowers are amazing plants. Since more than two years, we've planted seeds in different areas. Many of us would never have guessed that it would actually work. Some of the areas we plant don't even have weeds on it. But sunflowers are strong and can obviously go through a lot of shit. Here's another example of it, sent by our friend Richard from Guerrilla Gardening. I wouldn't feel comfortable standing there with those trucks flying by. But, as Richard told me, without any care or watering, those sunflowers did almost reached the same height as the London double decker. Impressive.
