Prosartes lanuginosa aka Hairy Mandarin

Prosartes lanuginosa belongs to Liliaceae, the lily family. It is a perennial, so it lives for more than one year. Its names include yellow fairybells, liverberry, and yellow mandarin. It is native from southern Ontario into the eastern United States. Kew places it in the temperate biome, a broad climate zone. The RHS gives its range as eastern North America. It is not native to Britain or Ireland. British nurseries list it, but these records describe a North American plant.

This plant grows from rhizomes, which are stems below ground. Kew calls its life form a rhizomatous geophyte. Chicago Botanic Garden says it grows upright and is a perennial. Neither supplied species profile states its full height or width. So these sources give no sound size range for garden plans. They do not describe this species' leaf shape or stem texture. The RHS gives those traits for the genus, not this species alone.

Chicago Botanic Garden lists yellow blooms from March through June. It splits this time into March–April and May–June. That gives a broad bloom season, from spring to early summer. It does not point to one peak month. The supplied species records do not describe the fruit. Nor do they give scent, flower size, or pollinator details. The RHS accepts Prosartes lanuginosa as the correct name. It lists Disporum lanuginosum as a synonym, or another name. This links the older Chicago entry to the same species.

Chicago advises part shade or full shade for garden growth. It lists USDA hardiness zones 4–9 and moderate watering. This supports a shaded site with a moderate water supply. It does not show a preferred soil texture or pH. Chicago suggests its use in beds or borders. Its upright shape and yellow blooms are the listed garden traits. The Chicago page is an archive. Updates stopped after February 2022.

The supplied evidence gives no pest or disease warnings for this species. It makes no claims about parts people can eat. Nor does it state uses as medicine or risks from poison. The name liverberry does not mean any part is safe to eat. The lack of warnings does not show that it is safe, either. The supplied records leave these safety questions open.
