*Perennial vegetables are a joy to grow. Whereas traditional vegetable plots are largely made up of short-lived, annual vegetable plants, perennials are edible plants that live longer than three years. Grown as permaculture plants, they take up less of your time and effort than annual vegetables, and extend the harvesting season - avoiding the hungry gap between the end of the winter harvest and the start of the summer harvest of annual vegetables.

Unlike annual vegetables, perennials cover and protect the soil all year round, which maintains the structure of the soil and helps everything growing in it. Humous levels build up, nutrients don't wash out of the soil, and mycorrhizal fungi, critical for storing carbon within the soil, are preserved. Perennial plants also contain higher levels of mineral nutrients than annuals because they have larger, permanent root systems, capable of using space more efficiently

Written by gardening expert Martin Crawford, this book gives comprehensive advice on how to grow and care for both common perennial vegetables like rhubarb, Jerusalem artichokes, horseradish and asparagus and unusual edible plants such as skirret, red chicory, nodding onions, Babington's leek, scorzonera, sea kale, wild rocket, coppiced trees and aquatic plants.

With plenty of cooking tips, colour photographs and illustrations throughout and an A-Z of over 100 perennial edibles, it is an inspiration for all gardeners.

Résumé

In this book Martin Crawford gives comprehensive advice on all types of perennial vegetable (edible plants that live longer than three years), from ground-cover plants and coppiced trees to plants for bog gardens and edible woodland plants. There are many advantages to growing perennial vegetables, for example: they need less tillage than conventional vegetables and so help retain carbon in the soil the soil structure is not disturbed in their cultivation they extend the harvesting season, especially in early spring and, of course, they are much less work. Part One looks at why and how to grow these crops, and how to look after them for maximum health. Part Two features over 100 perennial edibles in detail, both common and unusual - from rhubarb to skirret; Jerusalem artichoke to nodding onions.
