Rogue Sunflowers

I love nothing more than feeding the birds in my garden, thankfully my cat Mitzy leaves them well alone and Hades - Chunky Munkie just watches them in fascination.  Well on the patio area that I feed the birds a few loose sunflowers seeds have wedged themselves between the slabs and have grown.  So having never grown a sunflower in my entire life, I now have 4 lovely sunflowers.  I did have 5 but something bit the head off one and chomped it up.  Well I suppose it did have a nice meal.
