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 Cherry Queen
Wait until all danger of frost has passed, then plant out Cherry Queen into warm soil; in most zones that means late spring. Planted then, it flowers from June to September.

Where these facts come from
Cherry Queen's height, spread, hardiness zones, sun and trait tags were checked against 9 published sources on July 29, 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.
