Ribes altissimum
Propagation: Seed - best sown as soon as it is ripe in the autumn in a cold frame. Stored seed requires 3 months cold stratification at 0 - 9°c and should be sown as early in the year as possible[1][2]. Under normal storage conditions the seed can remain viable for 17 years or more. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame for their first winter, planting them out in late spring of the following year
Cuttings of half-ripe wood, July/August in a frame[1].
Cuttings of mature wood of the current year's growth, preferably with a heel of the previous year's growth, November to February in a cold frame or sheltered bed outdoors[3][4].
Cultivation: Easily grown in a moisture retentive but well-drained loamy soil of at least moderate quality[5][4]. Does well in shade though does not fruit so well in such a position[5].
Hardy to about -20°c[4].
Plants can harbour a stage of white pine blister rust, so should not be grown in the vicinity of pine trees[6]. Plants in this genus are notably susceptible to honey fungus[4].
This plant is possibly useful as part of a breeding programme for red currants[7].
Range: E. Asia - N. China, Mongolia, Siberia.
Habitat: Taluses composed of large stones in the forest zone, often into the bald mountain zone[7]. Coniferous or mixed forests and forest margins on mountain slopes below 2000 metres in N. China[8].
Edibility: Fruit - raw or cooked. Small with a thick skin and a pleasant acid taste[7]. The fruit is abundantly produced in the wild[7]. The purplish-black fruit is about 7mm in diameter[8].
Pollinators: Insects
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Seed Ripens: Mid Summer-Late Summer
Flower Type: Hermaphrodite
Also Known As: R. petraeum altissimum. (Turcz.)Jancz.
