Do you know this nursery rhyme?
Mary, Mary, quite contrary,
How does your garden grow?
With silver bells, and cockle shells,
And pretty maids all in a row.
If you look closely at the leaves on the plants, they look like buttercup leaves, don't they? That's because ranunculus are members of the buttercup family and they have some characteristics (that's just a big word which means "things about them") in common. Go and find a buttercup leaf and compare it to the ones in the picture.
