Our guide first, then the quoted facts, linked to their sources.

Quoted facts about growing Capsicum pubescens from 4 source publications.

Our guide written by Pepperheads

Oregon State says the species name comes from the dense covering of hairs on the stems and leaves, and that the seeds are brown or black. Missouri describes purple corollas and black seeds. Oregon State describes fruit about 1 inch in diameter, round or bell-shaped and red when ripe, and both Oregon State and the Chile Pepper Institute print 175,000 SHU.

Oregon State says the species was domesticated in the Andes of northern South America, is adapted to high altitudes in the tropics, and needs a long growing season and a high tunnel or heated greenhouse to ripen in Oregon. Missouri names rocoto types and the 'Manzano' variety.

Illinois Extension lists Canario and Rocoto. The displayed quotations do not give a pubescens-specific germination temperature, spacing or days to maturity. See also our growing basics.
