About the genus · Sempervivum

Sempervivum is a genus of about 40 species of flowering plants in the family Crassulaceae, commonly known as houseleeks. Other common names include liveforever and hen and chicks, a name shared with plants of other genera as well. They are succulent perennials forming mats composed of tufted leaves in rosettes.

Cultivation

Grouped as a cactus or succulent, listed under the genus Sempervivum in the archetype table, and Kew describes it as “succulent perennial”.

Nothing derived: no habitat climate for this species.
How this section is made

Each card states this species' habitat figures with their sources, and what two fixed rules read from them; nothing here says what the plant does, wants or tolerates. The rules · the terms.

Group. Listed under the genus Sempervivum in the archetype table, and Kew describes it as “succulent perennial”. A group is taken only where Kew's description of the species agrees with the table's listing. The table gives no figure and no prose; the cold floor is the habitat's alone.

Climate across the habitat

No habitat climate can be derived: Only 1 distinct land cell of the climate grid holds an in-range record placed to within 10 km; three are needed for an envelope. 3 of the 4 in-range records are placed to worse than 10 km, or to no stated accuracy and fewer than three decimals or by something other than a person's observation, and cannot place a climate cell, though they count for the map and its marker.

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing.
Openly licensed records inside the range, framed on where they fall.
NativeTranscaucasus, Turkey · regions are the level-3 units of the World Geographical Scheme for Recording Plant Distributions, as Kew's World Checklist records ranges, some under historical names such as Yugoslavia or Czechoslovakia (how).
Map marker41.76, 43.23 · in the densest population, 3 records (75% of those in range)
Kew's description“succulent perennial” · “temperate” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on all 4 georeferenced records inside the native range, all openly licensed and shown on the map. Under a dozen records behind the map. No climate across the range is derived for this species. 3 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population of the 4 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.

Photographs

Not checked. iNaturalist was skipped (not asked) when this page was built; GBIF's observation records with coordinates hold none. Not a statement that none exist.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 3 datasets via GBIF.org; each carries its own licence.
