Some vegetable crops are permanent, and in the times before long-distance transport and supermarkets they were the main source of early spring vegetables in many places. These heirloom crops are gaining attention once again among those interested in local self-sufficiency, folks who haven't the time or strength for annual crops, and curious gardeners looking for something new. Perennials do take longer to germinate and need good care in the seedling stages: starting them in pots is ideal, and doesn't take much space. This collection includes an information sheet, and 6 packets of perennial vegetable seeds. Best for gardeners in zones 6 and above, or with winter protection in colder areas.
