Sylphide
Anemone coronaria 'Sylphide'
Sylphide blooms from March through May.
Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
Growing Sylphide
Plant it in full sun. It prefers moderate water. It is hardy in USDA zones 7–10. Expect it to reach about 12 in tall and 6 in wide at maturity, in roughly 1 year (checked).
What was checked
Fifteen fields were checked against named botanical sources, each recorded beside the sources that carried it, with every unsettled point written down and decided: mature height and spread, hardiness zones, sun, water, bloom months and color, the trait tags, soil, diseases, pests, toxicity, the plant's own names, and years to mature size, which rests on a recorded house rule where no publisher states one and is marked so. 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 Sylphide
Sylphide is a fall-planted bulb: get it in the ground 6 to 8 weeks before the ground freezes, typically October or November in zone 8, the middle of its hardy zones 7 to 10. It pays you back the following March to May.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 8, the middle of this plant's hardy range, start with zone 8 in October. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

Where these facts come from
Sylphide's height, spread, hardiness zones, sun, water, bloom months and color, years to mature size, trait tags, soil, diseases, pests and toxicity were checked against 12 published sources on August 23, 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.

Safety
All parts are poisonous. The sap holds protoanemonin, a vesicant: it reddens, swells and blisters skin, and eating it causes mouth pain, vomiting and diarrhea. per NC State and Cornell
