What was checked
Mature height and spread, hardiness zones, sun and the trait tags were checked against named botanical sources for this plant. The bloom months and water need on this page were not, and each fact above says which. 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 Giant Snowdrop
Giant Snowdrop is a fall-planted bulb: get it in the ground 6 to 8 weeks before the ground freezes, typically September or October in zone 5, the middle of its hardy zones 3 to 8. It pays you back the following February to March.

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.
