Pseudotsuga menzesii - Douglas Fir

Phylum: Magnoliophyta - Class: Pinopsida - Order: Pinales - Family: Pinaceae

Named after the man who brought it to Britain from America, the Douglas fir is a fast-growing source of valuable timber and is grown throughout Wales. The straight trunk makes it ideal for telegraph poles, pit props, fencing and flagpoles.

These trees can reach a height of more than 50 metres, but most are harvested at the age of 50 to 70 years - long before they reach their full size.

The cones fall intact and have long, three-pointed bracts.
