Summary

Impatiens parviflora (small balsam, or small-flowered touch-me-not) is a species of annual herbaceous plants in the family Balsaminaceae, native to some areas of Eurasia, naturalized elsewhere and found in damp shady places. Impatiens parviflora can grow in sandy, loamy, and clay soils and prefers moist soil. The name comes from the fact that ripe seed pods explode when touched to disperse seeds widely.

About the genus · Impatiens

Impatiens is a genus of more than 1,000 species of flowering plants, widely distributed throughout the Northern Hemisphere and the tropics. Together with the genus Hydrocera, Impatiens make up the family Balsaminaceae.

Cultivation

Seasons

The rain rule reads a summer growing season: 70% of the median year's rain (599 mm of 829 mm) falls in March to July and October to November, warmer than the year (wet-season mean 11.4 °C against a yearly mean of 8.5 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: September to January and April to May.

Rain

829 mm in the median year at the habitat, 599 mm of it March to July and October to November. Wettest month May at 114 mm, driest month January at 36 mm. Across the grid cells of the range the year's total runs 472 mm to 1,083 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 816 mm, is the year's rain at the top of the page; the 829 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: 12 to 43 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 4, the highest 90th-percentile month 45).

Warmth and air
Temperature

Monthly means: the coldest month's mean nightly low -9.9 °C in January (across the grid cells of the range -17.1 °C to -8.9 °C), the warmest month's mean daily high 26.4 °C in July (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is -9.9 °C, the coldest month's mean nightly low, January, 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 whose ground is too far above or below the typical spot to correct for, and are not used.

Humidity

Relative humidity at the habitat: 51 to 56% 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 10 records in 6 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.

The daily extremes were not used: the correction for elevation, -1463 m, is beyond the 1,000 m either way that a lapse rate is applied over, so the weather cell's ground is other terrain than the typical spot's. So no cold floor is read for this species, and the coldest month's mean nightly low is not taken as one. What that cell gave, so corrected, over 44 years: absolute minimum -25.4 °C, 1st-percentile night -15.9 °C.

How this section is made
Each figure is the median across the 6 grid cells holding the 10 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. A dash is a month one or more of those cells has no figure for in the grid (a variable CHELSA does not carry there), so no median is taken rather than one over fewer cells. Extremes and elevation were read at a typical spot in the range, cell 935:5139 (43.225, 76.975). Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Across the range: median and 10th–90th percentile of each month across the 6 distinct grid cells holding 10 of the 10 in-range records; extremes and elevation at the typical cell 935:5139 (its coldest month's mean nightly low nearest the median across cells); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 43.00_76.875, lapse-corrected -1463 m at 6.5 °C/km. Elevation: ETOPO 2022, 1015 m (cell mean).

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