Last year, I planted from seed a mix of red flowering annuals. I did not notice any of those annuals selfseeding, except one. That one reprodeced itself all over the yard, several hundred times. The plant in question is, I gather, a red-purplish flowered amaranth. To my delight, it attracts butterflies. It is also edible, although I dont plan to eat it. At least it is not poisonous.. Is there a way to figure out the exact species, so that I know more about it.?
