Variety details

Distinguishing Traits

Copra produces round, medium-sized bulbs with dark yellow skin and thin necks. Despite the assertiveness typical of storage onions, its flavor is described as exceptionally sweet along with a bold onion taste.

Uses

Copra is noted as a favorite for storing, keeping well for about 10 months so that cooks can draw on the harvest for cooking right up until the next planting time.

Performance

Copra is a hybrid onion bred as a long-day type, meaning it is suited to gardens with longer summer daylight hours needed to trigger bulbing.
