Monkey puzzles are dioecious, meaning male and female flowers grow on separate trees. Male catkins (pictured), are 10-centimetre-long clusters of narrow green stamens which turn yellow and then brown at the end of summer. Female catkins are spiny cones.

Cones are green and gold, with hair-like edges. They grow at the tips of branches. Cones ripen over two or three years and eventually turn brown and release large brown seeds.

Did you know?

The common name of 'monkey puzzle' was coined during the mid-1800s when Charles Austin, a noted barrister, on seeing the tree for the first time commented that climbing the spiny, spiralling branches would be a puzzle even for a monkey.

Mythology and symbolism

It is said that speaking while passing one will bring bad luck or cause you to grow a monkey's tail.

There is an old Fenland belief that planting a monkey puzzle on the edge of a graveyard would prevent the Devil from entering during a burial. This link with the Devil extends country-wide; many even believing that the Devil lives in the monkey puzzle tree.

It is possible that this story of the Devil living in the tree was invented by concerned parents trying to stop their children climbing the spiky branches.
