Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: 2 in-range records, none placed to within 10 km. 2 of the 2 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.
Openly licensed records inside the range, framed on where they fall.
NativeGreece · introduced: Great Britain, Czechoslovakia, Germany, Spain, Bulgaria, Belarus, Baltic States, Krym, Central European Russia, South European Russia, Northwest European Russia, Ukraine, West Siberia, Primorye, Transcaucasus, Inner Mongolia, Manchuria, China North-Central, Mongolia, Alberta, Manitoba, Saskatchewan, New York, Florida, Maryland · 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).
Kew's description“annual” · “temperate” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on all 2 georeferenced records inside the native range; the map shows only the 1 openly licensed one, which alone would put the marker in the same place. 638 records outside the WCVP native range not used. Under a dozen records behind the map. No climate across the range is derived for this species. 2 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.

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 98 datasets via GBIF.org; each carries its own licence.
