Pyracantha koidzumii
Propagation: Seed - best sown as soon as it is ripe in a cold frame[1]. Remove all the fruit flesh since this can inhibit germination[1]. Stored seed requires 3 months cold stratification, sow it as early in the year as possible in a cold frame[2]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the cold frame for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Cuttings of almost mature wood, 5 - 10cm with a heel, mid-August in a cold frame[3]. Pot up in October or the following spring[3].
Cultivation: Prefers a good well-drained, moisture retentive loamy soil[4][1]. Succeeds in any soil that is warm and not very heavy[5]. Another report says that it grows well in heavy clay soils. Succeeds in sun or part shade, though it does not fruit so well in a shady position[1]. Tolerates atmospheric pollution and reasonable exposure, though it requires protection from cold winds[1].
This species is not hardy in the colder areas of Britain, it tolerates temperatures down to between -5 and -10°c[1]. It succeeds outdoors at Kew[5].
Plants are susceptible to scab and fireblight[5], especially when they are grown on acid sandy soils[6].
Closely related to P. rogersiana[5].
There are a number of named forms selected for their ornamental value[1]. 'Santa Cruz', 'Rosedale' and 'Victory' all have fruits larger than the type species[1].
Range: E. Asia - Taiwan.
Habitat: Rocky valley areas, seashores, thickets, among shrubs[7].
Edibility: Fruit[8]. No more details are given. The fruit is about 7mm in diameter[1].
Pollinators: Bees
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Wind: Tolerates strong winds
Pollution: Tolerates environmental pollution.
In Leaf: Evergreen
Seed Ripens: Early Fall-Late Fall
Flower Type: Hermaphrodite
Heavy Clay: Grows in heavy-clay soils.
Known Hazards: Although no specific mention has been seen for this species, it belongs to a genus where most, if not all members of the genus produce hydrogen cyanide, a poison that gives almonds their characteristic flavour. This toxin is found mainly in the leaves and
