Rubus ulmifolius (common name: elm-leaved bramble)
Propagation: Seed - requires stratification and is best sown in early autumn in a cold frame. Stored seed requires one month stratification at about 3°c and is best sown as early as possible in the year. Prick out the seedlings when they are large enough to handle and grow on in a cold frame. Plant them out into their permanent positions in late spring of the following year.
Cuttings of half-ripe wood, July/August in a frame[1].
Tip layering in July. Plant out in autumn.
Division in early spring or just before leaf-fall in the autumn[1].
Cultivation: Easily grown in a good well-drained loamy soil[2][3][1]. Succeeds on chalk or clay soils, preferring open habitats in the wild[4][5]. Tolerates poor soils so long as they are not dry[6]. Succeeds in sun or semi-shade[2][3][1] and also in deep shade though growth is more lax in such a position[6].
Hardy to about -18°c[6].
Plants reproduce sexually and not apomictically like many brambles. Individual plants are self-sterile[4].
This species is a blackberry with biennial stems, it produces a number of new stems each year from the perennial rootstock, these stems fruit in their second year and then die[1].
Plants in this genus are notably susceptible to honey fungus[1].
Range: Europe, including Britain, from he Netherlands south and east to N. Africa, Italy and Macaronesia.
Habitat: Very common in many habitats, succeeding on chalk and clay and preferring open sunny habitats[3][4][5].
Edibility: Fruit - raw or cooked[7][8]. Aromatic, but with small dryish drupelets[3]. Sweet[9].
Usage: A purple to dull blue dye is obtained from the fruit[10].
The root yields an orange dye when mixed with salt[9].
Pollinators: Insects
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Seed Ripens: Late Summer
Flower Type: Hermaphrodite
Heavy Clay: Grows in heavy-clay soils.
Also Known As: R. discolor. Syme. non Weihe.&Nees.
