Flowers should have a chance of spreading if a bee pollinates it

When two flowers that are the same are beside each other and a bee pollinates one of them it should have a chance to grow another of the same flower 

unless its a rose then it has a chance of becoming a different color if the two mix can make another color

it'll add life to Minecraft seeing a flower field bloom over time.

Flower will only spread if there in a block radius from one another

The chance of it occurring cant be too high maybe like a 1 in 10 chance of spreading.

maybe a 1 in 30 chance when a bee fly's over grass when covered in pollen to cause grass to sprout from the ground.
