Type of Flowers
Sempervivum: Sempervivum is a genus of almost xl species of flowering plants inward the Crassulaceae family, known every bit houseleeks. Other mutual names include liveforever as well as hen as well as chicks. They are succulent perennials forming mats composed of tufted leaves inward rosettes. In favourable weather they spread speedily via offsets, as well as several species are valued inward tillage every bit groundcover for dry, sunny spots.
Houseleeks guide house from Kingdom of Morocco to Iran, through the mountains of Iberia, the Alps, Carpathians, Balkan mountains, Turkey, the Armenian mountains, inward the northeastern role of the Sahara Desert, as well as the Caucasus. Their mightiness to shop H2O inward their thick leaves allows them to alive on sunny rocks as well as stony places inward the mountain, subalpine as well as alpine belts.
Like another plants of Southern Europe, the ancestors of houseleeks are probable to convey a subtropical origin. Morphologically, they are closely linked amongst the genera Jovibarba, Aeonium, Greenovia, Aichryson, as well as Monanthes, occurring mainly inward Macaronesia (Azores, Canary Islands, Cape Verde, Madeira). Some botanists include unopen to or all of these genera inside a wider interpretation of Sempervivum, especially Jovibarba.
The lift Sempervivum has its root inward the Latin semper ("always") as well as vivus ("living"), because this perennial found keeps its leaves inward wintertime as well as is really resistant to hard weather of growth.The mutual lift houseleek is believed to stalk from the traditional do of growing plants on the roofs of houses to ward off lightning strikes.The found is non closely related to the truthful leek, which belongs to the onion family. Other mutual names reverberate the plant's ancient association amongst Thor, the Norse god of thunder, as well as the Roman Jupiter. Hence names such every bit "Jupiter's beard" as well as the German linguistic communication Donnersbart ("thunder beard").
The genus Sempervivum is slowly to recognize, but its species are frequently non slowly to identify. Even 1 unmarried clone tin plough over the axe await really unlike nether diverse increase weather (modifications) or unlike times of the year. The members of this genus are really similar as well as closely linked to each other. As a consequence, many subspecies, varieties, as well as forms were described, without well-defined limits betwixt them. As a minute consequence, at that topographic point is a high frequency of natural hybrids inward this genus as well as the possibility of back-crossings of these. However, to a greater extent than or less xl species tin plough over the axe move individualized inward the whole surface area of the genus, but at that topographic point are many to a greater extent than local populations, without nomenclatural valour but sometimes amongst their ain characters.
