Why choose Birch & Alder?
General
A great advantage of Birch and Alder over other
deciduous trees is their quick growth. A 4-6 foot seedling will
quickly develop into a fine tree of 20 feet or so. This makes them
invaluable in garden design, as they can provide a feature while the
rest of the garden slowly establishes around them. In addition, they
are ideal for shelter belts, reclamation of wasteland and biomass fuel.
Birch
These are beautiful, delicate-looking trees that look
great in large groups or as a little cluster of three trees. They
have some of the most amazing bark. From the stark ghostly white of
the jacquemontii; to the shades of cream and orange of the ermanii;
through to the pinks, reds and oranges of albosinensis and the dark
browns and cherry reds of certain utilis varieties. As if the colour
weren't enough, the bark peels off the trunk throughout the year.
This provides an amazing flame-like effect when backlit by the
sun, as the peeling bark looks almost transparent. The delicate
toothed leaves of Birch provide a soft, dappled shade. Lastly,
although they look delicate, most birch are extremely tough and will
grow virtually anywhere.
Alder
Whilst not having the showy bark of their cousins, the
Alders do have very attractive catkins. The spring displays of alders
like th e maximowiczii and hirsuta are lovely (far more impressive
than the humble hazel or willow). The big green catkins of the
maximowizcii can reach 5-6 inches in length. The leaves too are
larger and more attractive (if less delicate). Barks tend to be grey
and smooth, apart from the barbata or the mighty subcordata which
have rough, fissured bark. The Alders tolerance of water-logged soil
is one of it's most useful features. This allows planting of trees in
areas most other trees would keel over and die in.
