Summary
Tulipa urumiensis, the late tulip or tardy tulip, is a species of flowering plant in the family Liliaceae. It is a perennial growing from a bulb. By some sources the accepted name is Tulipa tarda. It has a leathery tunic that is glabrous on the inside. More on Wikipedia ›

About the genus · Tulipa
Tulips are spring-blooming perennial herbaceous bulbiferous geophytes in the Tulipa genus. Their flowers are usually large, showy, and brightly coloured, generally red, orange, pink, yellow, or white. They often have a different coloured blotch at the base of the tepals, internally.

Cultivation
Grouped as a bulb, tuber or caudex by the genus Tulipa, which is reliably one kind of plant (archetype table). The table holds no figure for this group, which spans too much for one minimum; the cold floor is the habitat's alone, and no prose comes from the table.
Its year Rain rule: a summer growing season, March to August and October in the northern hemisphere (March to August and October at the habitat, northern).
This species’ habitat figures, and what two fixed rules read from them.
The rain rule reads a summer growing season: 70% of the year's rain (472 mm of 637 mm) falls in March to August and October, warmer than the year (wet-season mean 10.6 °C against a yearly mean of 5.4 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: September to February and April.
Read from the median year of CHELSA monthly rainfall and mean temperature across the envelope cells: the rain rule takes the smallest set of months carrying 70% of the rain and calls it winter when its mean is more than half a degree below the year's, summer when more than that above, and neither in between; the temperature rule, used only under 120 mm, names the cooler six months when they are at least a degree cooler than the other six. Months are shifted for the other hemisphere only where the temperature curve gives a season to reverse. A reading of the curves, not an observation of the plant.
Rain Habitat rain 637 mm a year, wettest May at 97 mm, driest January at 26 mm (habitat calendar, northern hemisphere).

637 mm a year at the habitat, 472 mm of it March to August and October. Wettest month May at 97 mm, driest January at 26 mm. Across the envelope cells the year's total runs 484 mm to 1039 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).
CHELSA monthly precipitation, median year across the envelope cells. The rain that falls where the species is recorded; nothing about how the plant takes water.
Light Open sky over the habitat: 11 to 43 mol/m²/day.
This species’ habitat figures, with their source.
Open sky over the habitat: 11 to 43 mol/m²/day across the year (daily light integral, median year across the envelope cells, CHELSA; the lowest 10th-percentile month across the cells is 10, the highest 90th-percentile month 43).
CHELSA shortwave radiation at each envelope cell, a daily-mean flux taken to a daily total and converted at 2.07 mol of PAR per MJ. The sky over the habitat, measured; what reaches a plant under a rock, a shrub or a shade cloth is not.
Warmth and air Cold floor -18.1 °C (1st-percentile habitat night, NASA POWER).
This species’ habitat figures, with their source.
Coldest: the 1st-percentile night over 44 years at the typical cell is -18.1 °C, the absolute minimum -31.1 °C, about 163 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 33.0 °C. Monthly means: coldest night -12.7 °C in January (across the envelope cells -18.3 °C to -10.2 °C), warmest day 22.7 °C in July (median year across the envelope cells, CHELSA). Cold floor: -18.1 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).
NASA POWER daily minima and maxima 1981–2024 at the typical cell, lapse-corrected to its elevation; CHELSA monthly means, median year across the envelope cells, CHELSA. The cold floor is the figure named in its sentence. Not a measured survival limit for any plant in a pot.
Relative humidity at the habitat: 55 to 59% across the year (monthly means, median year across the envelope cells, CHELSA). A figure about the air, saying nothing about how the plant takes water.

Each figure is the median across the 15 grid cells holding the 18 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. Extremes and elevation were read at the typical cell 943:5117 (42.825, 75.875). Over 44 years there: absolute minimum -31.1 °C, 1st-percentile night -18.1 °C, 99th-percentile day 33.0 °C. Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Envelope: median and 10th–90th percentile of each month across the 15 distinct grid cells holding the 18 in-range records; extremes and elevation at the typical cell 943:5117 (its coldest month's mean night nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 43.00_75.625, lapse-corrected -58 m at 6.5 °C/km. Elevation: ETOPO 2022, 1558 m (cell mean).
