Metasequoia glyptostroboides - Dawn Redwood
Metasequoia glyptostroboides commonly known as Dawn Redwood, is native to China. Although shortest of the redwoods, it grows to at least 61 m (200 ft) in height. Previously it had been known to science only as a fossilhence, now, its odd name and fame as the ‘fossil tree’. It grows naturally only in isolated areas in East Szechwan and West Hopeh, China, Where it thrives best in shady moist localities, in ravines and on stream banks. By 1948, seedlings were being raised in Europe, and because the tree strikes fairly easily from cuttings it has since been widely planted as specimens by arboriculturists, and in a few small groves by silviculturists, as in 1953 at Leighton in Montgomeryshire, Huntley in Gloucestershire, and in 1955 at Bedgebury in Kent.
The tree has ascending branches, and persistent branchlets (reddish-brown when young) which carry green deciduous branchlets 8 cm or more in length. The small opposite winter buds are usually below the scar of the side shoot. The two-ranked needles, usually 2.5 cm or more in length, are arranged in intricate and delicate patterns. It is one of the first trees to show green in spring – a pale fresh green – later turning to bright green on the upper surface lighter green or slightly glaucous on the under surface. Throughout summer the foliage changes through various shades of greenish-bronze, often with a pinkish tinge. In year of average autumn colors, the foliage has a moderately long spell of a yellowish pink and salmon pink before going pale brown, but in good sunny years it changes from this pink through brick-red to a rich dark rust-red. In autumn the needles are reddish-brown before they are shed along with the deciduous branchlets.
The male flower is ovoid, up to 1 cm long; the female conelet is sub-globose or short cylindrical, about 2 cm long, and pendulous.
The rough bark is soft and of pinkish-buff or reddish-brown shades. The older European trees are beginning to develop the picturesque ruggedness reported from China an unfortunately for the silviculturists, to develop knotty, ridged and pocketed boles with rapid taper. The tree grows rapidly at first (up to 1 m a year) and continues to tallest are already over 20 m. (66 ft).

Dawn Redwood is proving a fascinating ornamental tree and is particularly welcome for its spring and summer foliage, and its autumn tints. Even in winter the bare stems are enriched by the red-brown flakes of bark and pale brown, smooth stem between the raised flakes.

Picea abies - Norway Spruce

Picea abies commonly known as Norway Spruce, is native to Europe. It is one of European best known conifers, being her traditional Christmas Tree. It is introduced from Europe or Scandinavia around 1500, and increasingly planted all other countries from the seventeenth century. It is a large and fast-growing evergreen coniferous tree that grows 35–55 m (115–180 ft) in height and with a trunk diameter of 1 - 1.5 m (3-6 ft). It grows fast when young, up to 1 m (3 ft) per year for the first 25 years under good conditions, after that becomes slower once over 20 m (66 ft) in height. Sometimes it grows over 55 m (180 ft). The tallest measured Norway spruce, 62 m (204 ft) in height, grows near Ribnica na Pohorju, Slovenia.
The young shoots are reddish-brown to orange-red. The buds are yellow-brown smooth, pointed, and free of resin. The needles are light to dark green, stiff, up to 2.5 cm long, four-sided, and end in a point which is not harshly sharp. They lie in a shallow plane with distinct upper and lower sides. Each needle stands on a little peg projecting from the twig and when pulled away, the peg goes with the needle, accompanied by a short strip of bark; needles that fall naturally leave their pegs behind. The new pale green needles which appear in June fringe the edges of all the branches, giving the tree its best appearance.
The flowers of both sexes are found on the same tree. The clusters of stalked male catkins are about 2.5 cm long, oval, pendulous or spreading, red at first but becoming yellow in May. The female flowers usually higher up the tree; are small oval erect structures, stalk-less and green or even crimson-colored. After fertilization the conelets change to green or violet-purple, and gradually turn over until in the autumn they are pendent, long cylindrical cones, becoming light reddish-brown in the process and 10-15 cm long with compact scales having a texture like tough paper. The cones, usually towards the top of the tree, fall some considerable time after most of the winged seeds have been released in mid-autumn.

The bark is reddish-brown at first, and looks smooth – though rough to the touch because of small fibrous scales or small irregularities. Later it becomes greyish-brown with a reddish sheen on the exposed side and breaks into small, thin, scales; in all but very old trees it remains thin. The tree is at first conical in shape, later developing a narrow crown, with short sometimes drooping branches. The base usually broadens and is often buttressed. The wood is tough and elastic, but has no natural durability out of doors, and its heartwood is hard to treat with preservatives. White to pale yellow in color, without color distinction of heartwood and sapwood, it is much used for box-making, interior joinery and carpentry, paper pulp, chipboard, pit-props, and general purposes. In the trade it is usually called ‘white wood’.

Foresters find this tree in some respects more accommodating than Sitka Spruce, and it grows better than Sitka in the drier eastern parts. However, Norway Spruce in general is more sensitive to exposure, less wind-firm, slower growing, and produces a smaller volume of timber. Yet it will thrive under frosty conditions in Europe where Sitka will not. In young pole-stage regimented plantations, the straw colored leader is prominent feature.
