Description

The sugar root is an ancient, mildly sweet root vegetable that was prized in medieval monastery gardens. A plant produces a cluster of finger‑thick, white roots that, when cooked or fried, resemble a sweet parsnip.

Care instructions

Sow from March in the house before or directly into the bed when the soil has warmed, and expect slow germination. Keep the bed moist and weed‑free and harvest from October; the roots remain frost‑hardy in the ground and taste sweetest after the first cold nights.
