Compare the Governor's garden with the gardens in Old England. What is Significant about the difference?

As Hester awaits he meeting with the governor Pearl peers across the garden and sees a Puritan version of the great gardens of old England. It is practical with cabbages and pumpkin vines, a few rose bushes and apple trees. Like all things Puritan, the garden was a picture of organized austerity. THere was a "grey gloom" about it rather than the fancy ornamentation of a British garden belonging to a man of similar stature.
