Unlike the specimen shown here, many yew trees have trunks formed by a coalescence of several stems, and they tend to become hollow when they grow old.

In early spring the yews can be seen in flower, and in late summer the fruits appear. The seeds contain a poisonous alkaloid. The fruits, with their bright arils (the fleshy covering over the seeds), look at first like small acorns, but they ripen into bright red berries. It is the seed inside the fruit that is poisonous.
