Miniature Sunflower

So, I've dabbled in gardening before (hardware store potted colour, stuff like that), but my partner has never grown anything in his life. I bought a packet of miniature Sunflower seeds a few months ago and planted a couple in our front garden bed, then gave my partner the rest to plant in the back bed. For comparison, the first couple of shots are of my plants, the rest are of his, which have grown into these Audrey II looking space cabbages for some reason. I'm thinking it was the high nitrogen fertilizer he used, but whatever the cause I think it's kind of cool. Also, his plants seem to have become mothers!
