Yew
The Yew is a well-known tree of churchyards, but also grows wild on chalky soils. Yew trees can live for hundreds of years, turning into a maze of hollow wood and fallen trunks beneath dense foliage.
Yorkshire-fog
The soft, downy look of Yorkshire-fog makes it an attractive plant, even if it is considered a weed of cultivated land! It is also attractive to the caterpillars of the Small Skipper butterfly as a foodplant.
Zebra spider
As its name suggests, the zebra spider has the familiar black-and-white stripes of a zebra, making it very distinctive. It can be found stalking its prey on rocks, trees and walls, particularly in gardens.
