Verification
What this means

Written with AI assistance and not yet checked plant by plant against recorded sources, so treat every fact above as a starting point. Its scientific name was checked against botanical registries, an audit keeps its values consistent with the rest of the library, and a July 2026 review re-read the main facts of every plant then in the library against horticultural authorities without recording a source for each, which is why none of that counts as checked here. The source-by-source check is working through the whole library in the open, and a checked plant says so in this row.

When to plant George Davison

George Davison is a summer bulb planted in spring: get it in after the last frost, once the soil has warmed, April or May in zone 7, the middle of its hardy zones 5 to 9. It is hardy in zones 5 to 9, where it can stay in the ground over winter; colder than zone 5, lift and store it before the ground freezes. Expect flowers from July to August.

Month-by-month timing for your zone is on the planting calendar; if you garden near zone 7, the middle of this plant's hardy range, start with zone 7 in April. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.
