Pines Firs and Spruce

Picea abies, commonly known as the Norway spruce, is a prominent coniferous tree native to Northern, Central, and Eastern Europe. Recognisable by its tall, symmetrical shape and dense, evergreen foliage, it often reaches heights of 35–55 metres, with some specimens growing even taller under optimal conditions. The Norway spruce is widely planted in Europe and North America, not only for ornamental and landscaping purposes but also for timber production, given its straight grain and versatility. Its wood, known as "whitewood," is prized in the construction industry and is also used in the manufacture of paper and musical instruments.

The tree's bark is brown to reddish and scaly, becoming rougher as it ages. Its branches grow in horizontal layers, with pendulous branchlets giving the tree a slightly weeping appearance. Needles are dark green, pointed, and around 1–2 cm in length. Cones are one of its defining features, typically measuring 10–18 cm, with a cylindrical shape and rounded, overlapping scales that turn brown as they mature.

Picea abies is hardy, thriving in a range of climates and soil types, though it prefers well-drained, acidic soils and benefits from full sun. In colder climates, it is often cultivated as a Christmas tree due to its classic conical form and appealing fragrance. However, it requires ample space for its expansive root system, making it unsuitable for small gardens.

Ecologically, the Norway spruce plays an essential role in forest ecosystems, providing habitat and food for various wildlife species.

The Metasequoia glyptostroboides, commonly known as the dawn redwood, is a deciduous conifer belonging to the family Cupressaceae. It is one of only three species of redwood trees and is renowned for its prehistoric origins, often referred to as a "living fossil." 

This remarkable tree can grow to impressive heights of up to 40 metres (130 feet) with a conical shape. The bark is reddish-brown, fibrous, and peels off in long strips, giving it a distinctive appearance. The leaves are needle-like, arranged oppositely on the branches, and turn a rich bronze or golden-brown before falling in the autumn.
