Charlie's new growing project!

Following the success of the strawberry plants we have a new project in our garden! We are attempting to grow sunflowers!! I love sunflowers and really hope we get a good growth!! Charlie planted a sunflower seed at nursery a few weeks ago but he accidentally dropped it and the seed was lost :( So Aunty Elizabeth has come to our rescue and very kindly gave us these 3 plants. Charlie has decided who's plant is who's (although Aunty Elizabeth did stipulate that Charlie had to have the biggest!!) and the challenge is on, I wonder who's will grow the tallest!!! (I've told Mark he's not allowed to swap sticks, LOL!!)
