Synonyms:Betula crenata, Betula glandulifera.
Common Names: American Dwarf Birch, Resin Birch, Shrub Birch,Scrub Birch
Habitat :Betula glandulosa is native to North-western N. America – Newfoundland to Alaska, southwards on mountain ranges. It grows on streambanks, marsh margins, lakes and bogs, also found on alpine slopes.
Betula glandulosa is a multi-stemmed deciduous shrub typically growing to 1–3 m tall, often forming dense thickets. The trunks are slender, rarely over 5–10 cm diameter, with smooth, dark brown bark. The leaves are nearly circular to oval, 0.5–3 cm long and 1.2.5 cm broad, with a toothed margin. The fruiting catkins are erect, 1-2.5 cm long and 5–12 mm broad…CLICK & SEE THE PICTURES
It is not frost tender. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Wind.
It is closely related to the Dwarf Birch (Betula nana), and is sometimes treated as a subspecies of it, as B. nana subsp. glandulosa. It is distinguished from typical B. nana by the presence of glandular warts on the shoots and longer leaf petioles. Hybrids with several other birches occur.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in heavy clay and nutritionally poor soils. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
Succeeds in a well-drained loamy soil in a sheltered position. Grows well in heavy clay soils. Shade tolerant. B. glandulifera, mentioned above as a synonym of this species, might be a separate species in its own right. This species is native to areas with very cold winters and often does not do well in milder zones. It can be excited into premature growth in mild winters and this new growth is susceptible to frost damage. The branches are covered in aromatic glands, and the leaves are pleasantly fragrant when crushed. Hybridizes freely with other members of this genus. This species is closely related to B. nana. Trees are notably susceptible to honey fungus.
Seed – best sown as soon as it is ripe in a light position in a cold frame. Only just cover the seed and place the pot in a sunny position. Spring sown seed should be surface sown in a sunny position in a cold frame. If the germination is poor, raising the temperature by covering the seed with glass can help. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. If you have sufficient seed, it can be sown in an outdoor seedbed, either as soon as it is ripe or in the early spring – do not cover the spring sown seed. Grow the plants on in the seedbed for 2 years before planting them out into their permanent positions in the winter.
Edible Uses:Young leaves and catkins – raw. The buds and twigs are used as a flavouring in stews.
