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
Seasons
The rain rule reads a winter growing season: 70% of the median year's rain (537 mm of 763 mm) falls in November to February, cooler than the year (wet-season mean 13.1 °C against a yearly mean of 17.6 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: May to August.
Rain
763 mm in the median year at the habitat, 537 mm of it November to February. Wettest month December at 173 mm, driest months (2 at 0 mm); 3 months under 5 mm. Across the grid cells of the range the year's total runs 721 mm to 854 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 735 mm, is the year's rain at the top of the page; the 763 mm here is the median year's, the twelve monthly medians added, which the rain rule reads. Habitat calendar, northern hemisphere; median year across the grid cells of the range, CHELSA.
Light
Open sky over the habitat: 13 to 50 mol/m²/day across the year (daily light integral, median year across the grid cells of the range, CHELSA; the lowest 10th-percentile month across the cells is 11, the highest 90th-percentile month 51).
Warmth and air
Monthly means: the coldest month's mean nightly low 10.0 °C in February (across the grid cells of the range 1.8 °C to 10.4 °C), the warmest month's mean daily high 25.4 °C in August (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 10.0 °C, the coldest month's mean nightly low, February, in the median year (CHELSA); a month's mean of its nightly lows is warmer than the nights a floor is read from. The daily extremes were read at a weather cell that is mostly sea and are not used.
Relative humidity at the habitat: 57 to 61% across the year (monthly means, median year across the grid cells of the range, CHELSA). A figure about the air, saying nothing about how the plant takes water.
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.
Seasons. Read from the median year of CHELSA monthly rainfall and mean temperature across the grid cells of the range: 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 moves 4 °C or more and the habitat lies 10° or more from the equator. A reading of the curves, not an observation of the plant.
Rain. CHELSA monthly precipitation, median year across the grid cells of the range. The rain that falls where the species is recorded; nothing about how the plant takes water.
Light. 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.
Temperature. CHELSA monthly means, median year across the grid cells of the range. No cold floor is read without a daily extremes series; the coldest month's mean nightly low named in its sentence is not one. Not a measured survival limit for any plant in a pot.
Humidity. CHELSA relative humidity, median year across the grid cells of the range.
Climate across the habitat
From few records: this habitat climate is read from 4 records in 3 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.
Habitat months, northern hemisphere
Mean daily high from 13 °C in Jan and Feb to 25 °C in Jul and Aug; mean nightly low from 10 °C in Feb to 23 °C in Jul and Aug. The cold quarter, Jan to Mar, is the three months around the coldest month's mean nightly low. 763 mm of rain in the median year (the twelve monthly medians added), the wettest month Dec. The bands show the 10th to 90th percentile across 3 habitat cells. Beneath: daily light integral and relative humidity through the year, each on its own scale.

The daily extremes were read at a NASA POWER cell that is 28% land: neither it nor the next candidates whose coldest month's mean nightly low is within 2 °C of the median across cells sit in a POWER cell that is mostly land, and the rule reads a cold floor only from a cell that is mostly land, so none is read for this species. Nor is the coldest month's mean nightly low taken as one: it is a mean of a month's lows, not its coldest night. What that cell gave over 44 years: absolute minimum 0.6 °C, 1st-percentile night 4.6 °C, 99th-percentile day 31.7 °C.
