The rocambole onion (Allium proliferum)
It generates new plants from small bulbils produced at the top of the stem, which eventually fall and root, hence its name. It can be harvested from spring to autumn as needed.
Other useful plants
Curled sorrel (Rumex crispus)
Curled sorrel is a useful plant in the garden. It has medicinal properties and can be used to relieve bee stings. It has a slightly bitter taste but is rich in nutrients.
Brassicaceae
Brassicaceae such as kale are essential in a food forest. They produce edible leaves very early in the spring. Letting some plants go to seed ensures a continuous harvest year after year, by allowing new seeds to germinate spontaneously.
Rhubarb (Rheum rhabarbarum)
Rhubarb is another valuable perennial. It grows strongly in spring and produces edible stems for several years. To optimize its growth, it is recommended to remove the flower stalks to encourage stem production.
Conclusion
Adopting perennial species in your garden allows you to obtain a continuous supply of food without having to replant every year. In addition to providing an early harvest, these plants enrich the soil and attract pollinators, thus contributing to a balanced and self-sufficient ecosystem.
By experimenting with different plants and observing their interactions, you can develop a resilient and productive garden that requires less maintenance each year. Permaculture offers a sustainable and nourishing way to cultivate the land, in harmony with nature.
