Summary

Muscari neglectum is a perennial bulbous flowering plant in the asparagus family Asparagaceae. Members of this genus are commonly known as grape hyacinths, and M. neglectum is known as common grape hyacinth or starch grape hyacinth. Muscari are perennial bulbous plants native to Eurasia. They produce spikes of dense, commonly blue, urn-shaped flowers. More on Wikipedia ›

About the genus · Muscari

Muscari is a genus of perennial bulbous plants native to Eurasia that produce spikes of dense, most commonly blue, urn-shaped flowers resembling bunches of grapes in the spring. The common name for the genus is grape hyacinth, but they should not be confused with hyacinths. A number of species of Muscari are used as ornamental garden plants.

Cultivation

Its year Rain rule: no season, 70% of the rain takes 8 months (September to January and April to June in the northern hemisphere).

This species’ habitat figures, and what two fixed rules read from them.

The rain rule reads no season: 70% of the year's rain (582 mm of 795 mm) takes 8 months, September to January and April to June. Mean temperature moves 17.4 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: March to July and October to December.

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 795 mm a year, wettest October at 85 mm, driest July at 50 mm (habitat calendar, northern hemisphere).

This species’ habitat figures, with their source.

795 mm a year at the habitat, 582 mm of it September to January and April to June. Wettest month October at 85 mm, driest July at 50 mm. Across the envelope cells the year's total runs 561 mm to 1201 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: 9 to 42 mol/m²/day.

This species’ habitat figures, with their source.

Open sky over the habitat: 9 to 42 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 5, the highest 90th-percentile month 47).

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 -4.7 °C (1st-percentile habitat night, NASA POWER).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -4.7 °C, the absolute minimum -14.1 °C, about 48 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 35.7 °C. Monthly means: coldest night 0.7 °C in January (across the envelope cells -4.1 °C to 4.5 °C), warmest day 25.6 °C in July (median year across the envelope cells, CHELSA). Cold floor: -4.7 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Climate across the habitat

Habitat climate through the yearMean day from 7 °C in Jan to 26 °C in Jul; mean night from 1 °C in Jan to 16 °C in Jul. The cold quarter, Dec to Feb, is the three months around the coldest night. 795 mm of rain a year, most in Oct. The bands show the 10th to 90th percentile across 1434 habitat cells. Over 44 years at the typical cell the absolute minimum was -14.1 °C and the 99th-percentile day 35.7 °C; neither is dated to a month.

Each figure is the median across the 1434 grid cells holding the 1590 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 948:3548 (42.575, -2.575). Over 44 years there: absolute minimum -14.1 °C, 1st-percentile night -4.7 °C, 99th-percentile day 35.7 °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 1434 distinct grid cells holding the 1590 in-range records; extremes and elevation at the typical cell 948:3548 (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 42.50_-2.500, lapse-corrected +7 m at 6.5 °C/km. Elevation: ETOPO 2022, 686 m (cell mean).

Similar habitat climate the 6 species whose habitat climate is nearest this one's: mean day and night, month by month, and rain on a log scale, in calendar order, so a habitat with the same seasons six months out is far, not near. Nothing else counts: not range, not family.
