What is planted in Mary Mary Quite Contrary's Garden?

using mainly spoons and manure, she grows silver bells and cockle shells. It's quite magnificent in the springtime. I hear that she has an entry to this year's Chelsea flower show. The pretty maids don't live there any more, they went to university last Easter.

Well actually that nursery rhyme was decatied to a queen that was ruthless.

Mary Tudor, she murdered many ppl because of their reliagion the flowers are tombstones and the sliver belles are the gullitone or the bells that toll when some one dies. her nick name was "bloody Mary" there is also some debate if its really about Mary Queen of Scots
