What this means
Listed on October 3, 2026, from two published pages: Plant Addicts and NC State Extension. Its mature size, hardiness zones, sun, bloom time and trait tags were read off those pages and recorded beside them. It has not yet been checked against the wider botanical literature, so treat the numbers as a starting point. Years to mature size is a house convention, taken from the plants of the same kind already in the library. The source-by-source check works through the whole library in the open, and a checked plant says so in this row.

When to plant Black Dragon Japanese Cedar
Plant Black Dragon Japanese Cedar 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 7, the middle of its hardy zones 5 to 9, that is March to May, or September on the fall side.
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 March. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.
