What this means
Listed on October 1, 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.
