The impatiens ( Impatiens walleriana , Swiss German : Süüfferli because of the relatively high water demand) is a plant from the genus of impatiens ( Impatiens ) in the family of balsaminaceae (Balsaminaceae).
features
The hard-working Lieschen is an evergreen , perennial herbaceous plant ; it is usually cultivated as an annual plant . This kind reaches stature heights up to 30 (rarely up to 70) centimeters.
The alternate, simple leaves are stalked 1.5 to 6 cm long. The leaf blade is ovate to broadly elliptical, sometimes obovate, 2.5 to 13 inches long and 2 to 5.5 inches wide, green and sometimes spotted or pink or reddish on the underside. Stipules are missing.
The flowers are singly or usually in pairs or rarely up to five together. The hermaphroditic, zygomorphic flowers vary in size. The lower sepals are weakly boat-shaped and suddenly narrow into the 2.8 to 4.5 centimeters long, thread-like curved, but not back-curved spur. The five petals are free and spread out flat. The colors of the petals range from white, pink, violet, purple, red to orange. There is only one circle with five stamens . The ovary is on top. The style is short or absent and ends in one to five scars. The smooth, "explosive" capsule fruit is 1.5 to 2 cm in size.
The flowering period extends from January to December for the cultivar.
The number of chromosomes is 2n = 16.
Occurrence
The hard-working Lieschen is native to Kenya , Tanzania , Mozambique , South Malawi and East Zimbabwe . This species can be found here in damp, shady places, damp rocks, coastal and mountain rainforests at altitudes from 0 to 2000 meters.
use
The hard-working Lieschen is cultivated as an ornamental plant in planters, summer borders and window boxes. It has been in culture since 1880 at the latest. There are numerous varieties that differ in height, flower and leaf color. There are also double-flowered varieties.
etymology
The generic name Impatiens is Latin and means "impatient, sensitive". It comes from the sensitive fruits of the species of this genus, which pop open when lightly touched ( juice pressure spreader ). The name walleriana was given to the species by Joseph Dalton Hooker , who newly described the species in the Flora of tropical Africa by Daniel Oliver and who wanted to immortalize one of the first discoverers, the missionary Horace Waller (1833-1896). Waller worked in Africa for several years and had also collected plants. He had the new species together with Dr. John Kirk found in Mozambique . Waller later became known for editing the diaries of the African explorer David Livingstone .
