Summary

Maianthemum stellatum (star-flowered, starry, or little false Solomon's seal, or simply false Solomon's seal; star-flowered lily-of-the-valley or starry false lily of the valley; is a species of flowering plant, native across North America. It has been found in northern Mexico, every Canadian province and territory except Nunavut, and in every US state except Hawaii and the states of the Southeast. It has little white buds in the spring, followed by delicate starry flowers, then green-and-black striped berries ripening to deep red or black in the fall.

About the genus · Maianthemum

Maianthemum includes the former genus Smilacina and is a genus of perennial herbaceous flowering plants with fleshy, persistent rhizomes. It is widespread across much of North America, Europe and Asia, and may be terrestrial, aquatic or epiphytic. It is characterized by simple, unbranched stems that are upright, leaning or hanging down and have 2–17 foliage leaves. More on Wikipedia ›

Each sentence is one card's own one-line form, written by the same rule as the card (Its year, Rain, Light, Temperature); the note cannot say what a card does not. Months are given for the northern hemisphere (set your site in Settings to change this), and the habitat's own alongside. The cards · the figures.

Cultivation

Its year Rain rule: no season, 70% of the rain takes 8 months (April to August and October to December 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 (596 mm of 840 mm) takes 8 months, April to August and October to December. Mean temperature moves 24.6 °C between the warmest and coldest month. Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: October to February and April to June.

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.

840 mm a year at the habitat, 596 mm of it April to August and October to December. Wettest month June at 82 mm, driest February at 54 mm. Across the envelope cells the year's total runs 438 mm to 1580 mm (10th to 90th percentile of each cell's own year) (median year across the envelope cells, CHELSA; habitat calendar, northern hemisphere).

Open sky over the habitat: 8 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 51).

Temperature

Coldest: the 1st-percentile night over 44 years at the typical cell is -13.4 °C, the absolute minimum -23.3 °C, about 105 frost nights a year (NASA POWER daily minima). Warmest: the 99th-percentile day is 23.7 °C. Monthly means: coldest night -9.3 °C in January (across the envelope cells -15.1 °C to 0.7 °C), warmest day 24.8 °C in July (median year across the envelope cells, CHELSA). Cold floor: -13.4 °C, which is the 1st-percentile night over 44 years at the typical cell (NASA POWER).

Each figure is the median across the 1502 grid cells holding the 1882 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 896:1857 (45.175, -87.125). Over 44 years there: absolute minimum -23.3 °C, 1st-percentile night -13.4 °C, 99th-percentile day 23.7 °C.
