PDC LESSON 3.7 SEEDS – BIENNIALS – PERINNIALS – LEGUMES

 

Biennials - Perennials - Legumes

are plants that produce vegetative growth during the first growing season, slow down through a period of cold weather then go to seed the second growing season, and then die.

Root crops

will take two calendar years for seed production. Onions, carrots, and celeriac seed can be obtained by root to seed production. Simply plant the sprouting end of a carrot or onion and allow it to grow and form the seed head then save for seed saving. This will take only half the time as in seed-to-seed production.

Perennials

are the types of plants that can survive on neglect. This is one of the main reasons why many different varieties have been adapted into permaculture gardens.

Root crops

such as sweet potatoes, taro, arrowroot, yam, ginger, turmeric, and water chestnuts, all die back in the cooler weather only to re-shoot again when the weather warms up.

Leaf crops

such as aibika, New Zealand spinach and kang kong will die back with the cooler weather and re-shoot again in spring/ summer.

Legumes

such as the seven-year bean varieties (of which there are many) yam bean, Madagascar bean, lab lab and the scarlet runner bean all die back in the cooler weather only to regrow again in spring.

Other plants can be divided by crowns

such as lemon grass, rhubarb, asparagus, yakon, and divider leeks.

All these plants will keep on growing and producing more planting material by vegetative propagation.
