Description
Appearance and foliage leaf
The Siebold primrose is a perennial herbaceous plant with plant height 12 to 25 ( to 30) centimeters.
The in a basal rosette standing together leaves consist of petiole and leaf blade. The hairy petiole has a length of 4 to 12 ( to 18) centimeters. The multicellular and greyish hair -bearing leaf blade is ovate -oblong nearly rounded to truncate with a length of 4 to 10 inches and a width of ( 2) 3 to 7 centimeters to elongate and at Spreitengrund cordate or rarely. The leaf margin sinuate - lobed and the tip appears rounded. The lobes are notched - toothed.
Inflorescence and flower
The flowering period is in May. The 12 to 25 ( to 30) cm long inflorescence stem is hairy. The doldige inflorescence contains 5 to 15 flowers and with a length of 4 to 10 millimeters linear - lanceolate bracts. The weakly hairy or verkahlenden flower stems are 0.4 to 3 inches long.
The hermaphrodite flowers are heterostyl, radial symmetry and fünfzählig double perianth. The five 6-8 mm long, elongating during fruit formation up to 1.5 centimeters sepals are fused from the bell-shaped half or more. The lanceolate to ovate - lanceolate, pubescent or glabrous calyx teeth showing more or less spread. The five pink to lilac - purple and rarely white petals are fused into a 0.9 to 1.3 cm long corolla-tube. The 1 to 2 ( to 3) inches wide coronary band has inverted - ovate, at the top of doubly cleaved Kronblattlappen. The Heterostylie of the flowers shown by the fact that either the stamens spring from a little below the middle of the corolla tube and the pen is about as long as the corolla tube or the stamens spring from the uppermost portion of the corolla tube and the stylus is approximately half as long as the corolla tube is.
Fruit
The approximately spherical capsule fruit is about half as long as the calyx. The fruits ripen in June.
Chromosome number
The number of chromosomes is 2n = 22, 24, 26, 29, 36
Occurrence
The Siebold primrose is native to southeastern Siberia in Russia's north-eastern provinces of China, Japan and on the Korean peninsula. It settles wet habitats in forests.
System
The first description of Primula sieboldii was made in 1873 by Charles Jacques Édouard Morren in La Belgique Horticole, Volume 23, p.97. As synonyms for Primula sieboldii Primula E.Morren patens Turcz. , Primula are patens var genuina Skvortzow and Primula patens var called manshurica Skvortzow. Primula sieboldii belongs to the section cortusoides in the subgenus within the genus Primula Auganthus.
Primula sieboldii of three forms have been published, indicating their validity is unknown:
- Primula sieboldii f hortensis H.Takeda
- Primula sieboldii f patens ( Turcz. ) Kitag.
- Primula sieboldii f spontanea H.Takeda
Use
In Japan, Siebold primrose is traditionally cultivated for centuries. It is used in many countries around the world as an ornamental plant in parks and gardens. Through breeding, numerous varieties of Siebold incurred primrose.
