The Tudors followed Italian influence in creating gardens which mirrored the alignment of the house, creating a harmony of line and proportion that had been missing in the Medieval period. For the first time since the Romans left, sundials and statues were once more popular garden ornaments. But the most prominent contribution of the Tudors to gardening was the knot garden. Knots were intricate patterns of lawn hedges, usually of box, intended to be viewed from the mount, or raised walks. The spaces between the hedges were often filled with flowers, shrubs, or herbs. No Tudor gardens have survived intact, but some of the best examples still remaining can be glimpsed at Haddon Hall (Derbyshire), Montacute House (Somerset), and Hampton Court Palace (near London).

What is it about perennials that enables it’s winter survival abilities, whereas other plants will shrivel up and die as soon as the going get tough? Why can’t scientists engineer annuals or biennials to last as long the perennial plant?
