What was checked
Nine facts were checked against named botanical sources, each recorded beside the sources that carried it: mature height and spread, hardiness zones, sun, water, bloom months and color, the trait tags, and years to mature size, which rests on a recorded house rule where no publisher states one and is marked so. Soil, diseases, pests, toxicity and the plant's own names have not yet been read for this plant, and its trait tags are the ones a feature uses rather than every word a page prints. Each fact above carries its own mark. The planting, spacing and size sections are derived from these checked facts by a fixed rule, not checked separately, and the plant type is the library's own classification.
When to plant Yellow Blotch Pansy
Yellow Blotch Pansy is a cool-season annual: plant it out in early spring as soon as the soil can be worked, a few weeks before the last frost, since it takes light frost and fades in summer heat; in mild-winter zones it also goes in during fall. In a zone 5 garden that means April or May. It flowers from March to June.
Month-by-month timing for your zone is on the planting calendar. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

Where these facts come from
Yellow Blotch Pansy's height, spread, hardiness zones, sun, water, bloom months and color and trait tags were checked against 5 published sources on October 27, 2026. Each one is linked below with every fact it carried, which can include a fact this page still marks as not yet checked, because a source carrying a value is not the same as the value being held to the standard. Facts not in that list, and the planting, spacing and size sections, are not covered by these sources.
