Bay

This handsome evergreen tree makes a dense, if slow-growing hedge, and can be trimmed and trained for topiary, or just left to develop into a screening tree. 

The powerfully aromatic leaves are indispensable in the kitchen and are effective in ridding kitchen cupboards of weevils and cockroaches. Requires a sheltered position with adequate drainage. Can be prone to scale insects that are easily controlled with white oil. Long-lived and now available in several different leaf forms, they are just as popular in formal gardens as they are in edible landscapes.
