plants in which harvesting also makes new plants
Here in the part of California where I live, the native Miwok used to harvest Brodiaea bulbs at the right time of the year, using a digging stick. When they did this, it would break up the corms and make more Brodiaea bulbs. When the Europeans arrived and ended the Miwok's land management practices such as harvesting these bulbs, Brodiaea became a very rare plant, when it used to be abundant.
As a permaculture designer, this is a dream scenario. I am still trying to figure out where to find Brodiae bulbs to propogate in my garden, but I'm am also wondering about other plants that can be sown at the same time they are harvested in this manner.
Anybody know of any?
