Betula ermanii is a deciduous Tree growing to 25 m (82ft) by 5 m (16ft) at a fast rate.
It is hardy to zone (UK) 3 and is not frost tender. It is in flower in April, and the seeds ripen in September. 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.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.

Medicinal Uses


Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

Antiseborrheic;  Vulnerary.

Vulnerary. The bark is used to bandage wounds[61].
Other Uses
Pioneer.

The tree colonizes poor soils and cleared woodlands in the wild[11]. This makes it suitable for use as a pioneer species for re-establishing woodlands. It is a quite short-lived species, but grows fairly quickly and creates suitable conditions for more permanent trees to become established. Because its seedlings do not grow well in shady conditions, the birch is eventually out-competed by the other woodland trees.
Cultivation details
Succeeds in a well-drained loamy soil in a sheltered position[11, 200]. Grows well in heavy clay soils. Dislikes wet soils[200]. Shade tolerant[200]. A very polymorphic species[58], it hybridizes freely with other members of this genus[50]. The young growth in spring is subject to damage by late frosts[1]. A colonizer of poor soils and cleared woodlands, it tolerates very poor soils[11]. Trees are notably susceptible to honey fungus[200].
Propagation
Seed - best sown as soon as it is ripe in a light position in a cold frame[78, 80, 113, 134]. Only just cover the seed and place the pot in a sunny position[78, 80, 134]. Spring sown seed should be surface sown in a sunny position in a cold frame[113, 134]. If the germination is poor, raising the temperature by covering the seed with glass can help[134]. 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[78, 80, 113, 134].

Just discovered your site, excellent.With regards entry Betula ermanii if as you correctly say species is very polymorpic then its probably worth mentioning in propagation section that unless grown from a 'contained'stand of trees then seed unlikely to come 'true and would be best propagated by grafting

Thanks, your informative site was useful after encountering my first gold birch and thinking it was someone's festive aerosol decoration (of a silver birch, which, fittingly, is now my second favourite birch. My least is the one our headmaster wielded with aplomb. On another matter, it would be great to get photos up alongside the different tree speci. Perhaps you could get some digital donations from tree enthusiasts who post their photos on sharing sites such as flickr.com? Just a thought to add to this excellent resource... Or is my computer just not displaying your photos ?
