Ulmus macrocarpa
Propagation: Seed - if sown in a cold frame as soon as it is ripe, it usually germinates within a few days[1]. Stored seed does not germinate so well and should be sown in early spring[1]. The seed can also be harvested 'green' (when it has fully developed but before it dries on the tree) and sown immediately in a cold frame. It should germinate very quickly and will produce a larger plant by the end of the growing season[2]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Plants should not be allowed to grow for more than two years in a nursery bed since they form a tap root and will then move badly.
Layering of suckers or coppiced shoots[1].
Cultivation: Prefers a fertile soil in full sun[3], but is easily grown in any soil of at least moderate quality so long as it is well drained[4].
This species is resistant to 'Dutch elm disease', a disease that has destroyed the greater part of all the elm trees growing in Britain. The disease is spread by means of beetles. There is no effective cure (1992) for the problem, but most E. Asian, though not Himalayan, species are resistant (though not immune) to the disease so the potential exists to use these resistant species to develop new resistant hybrids with the native species[1].
The various species of this genus hybridize freely with each other and pollen is easily saved, so even those species with different flowering times can be hybridized[1].
Range: E. Asia - China, Japan.
Habitat: Sunny dry rocky mountain slopes in W. China[5]. Mixed forests, slopes, valleys at elevations of 700 - 800 metres[6].
Edibility: Leaves - raw or cooked.
The fruits are eaten in sauces. An emergency food, they are only used when all else fails[7].
Medicinal: The seed is anthelmintic, antidote, digestive, febrifuge, parasiticide, skin[8][9].
The bark contains tannins. It is astringent and has antimicrobial activities[10]. It is used in the treatment of chronic diarrhoea and internal parasites]279].
Usage: Used externally on body parasites[8]. No more details.
Pollinators: Wind
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Seed Ripens: Late Spring-Early Summer
Flower Type: Hermaphrodite
