Ribes maximowiczianum saxatile Kom.
Ribes komarovii is a much-branched deciduous shrub forming a dense, rounded crown; it can grow up to 250cm tall[
The plant is sometimes harvested from the wild for local use as a food. It is grown as an ornamental, valued especially for its lustrous foliage[
E. Asia - Russian Far East, northern and central China, North Korea
Scrub, open stony slopes, rocks, crests, calcareous outcrops[
|Cultivation Status||Ornamental, Wild
Species in this genus are generally easy to grow, preferring a position in sun (where they fruit best) or moderate shade and succeeding in most moist but well-drained soils of at least moderate fertility[
White pine blister rust, caused by the pathogen Cronartium ribicola, is a fungal disease that is native to Asia but has spread via human activity to many other regions, where it has become more virulent. It has a complex life-cycle that requires both currants (Ribes species) and white pines (Pinus species of the section Strobus) for the disease to spread. Whilst Ribes species can generally live with the disease (it has an annual life-cycle and infects the leaves only) Pinus species can be devastated by it (it becomes perennial and spreads through the tree). Young pines are far more susceptible than mature trees. In America the growing of certain Ribes species is banned in some areas in order to protect plantations of white pine species.
Plants in this genus tend to be notably susceptible to honey fungus[
A dioecious species, both male and female forms need to be grown if fruit and seed are required[
Fruit - raw or cooked. Used to make fermented drinks[
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[
]. 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, mid summer in a frame[
Cuttings of mature wood of the current year's growth, preferably with a heel of the previous year's growth, late autumn to late winter in a cold frame or sheltered bed outdoors[
