No toxicity note is on file for Celtic Pride Siberian Cypress. That is not a clearance: check its safety for people and pets before planting.
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 Celtic Pride Siberian Cypress
Plant Celtic Pride Siberian Cypress in spring once the soil is workable, or by very early fall at the latest: an evergreen needs its roots down well before the ground freezes. In zone 5, the middle of its hardy zones 2 to 7, that is April to June, or August on the fall side.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 5, the middle of this plant's hardy range, start with zone 5 in April. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

Where these facts come from
Celtic Pride Siberian Cypress' height, spread, hardiness zones, sun, water and trait tags were checked against 7 published sources on October 16, 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. Bloom was checked as well: Celtic Pride Siberian Cypress bears no flowers, so there is no bloom window for a source to carry.
