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 Chincherinchee
Chincherinchee is a summer bulb planted in spring: get it in after the last frost, once the soil has warmed, March or April in zone 8, the middle of its hardy zones 7 to 10. It is hardy in zones 7 to 10, where it can stay in the ground over winter; colder than zone 7, lift and store it before the ground freezes. Expect flowers from June to July.
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 March. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

Where these facts come from
Chincherinchee's height, spread, hardiness zones, sun and trait tags were checked against 6 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.
