Long Scarlet Radish, Heirloom Seeds

Long Scarlet Radish, Heirloom Seeds — The 1870 Cincinnati Market Radish That’s Ready in 35 Days

Long Scarlet (Raphanus sativus) — also known as Cincinnati Market — is a historic heirloom first described in the 1907 Landreth & Sons catalog and now becoming genuinely scarce. Long, tapered, deep red roots grow 6–7 inches with crisp, tender white flesh and medium tops perfect for bunching. A very heavy-yielding variety, excellent for home gardens and market. The 1935 Isabell Seed Catalog said it best: “The finest long red radish… no finer radishes go into any market. Grows perfectly straight and smooth, 6 to 7 inches in length. Skin scarlet-colored, very thin, the flesh crisp, brittle, and of a delightful flavor. Ready for the market in 35 days.”
