For months I have been pulling this weed. 

IT IS EVERYWHERE. First, there is a red tinted leaf on the soil, maybe purple. Then another and another. It is all over the place with no root. It is purslane. A weed to me, but actually edible and rather nutritious. It has antimutagenic properties, calcium, potassium, iron, vit C, some B and is used to cure digetsive ailments (constipation and urinary system inflammation). It produces a small yellow flower and then seeds. The flower opens for only a short time it eh morning light. Trives in dry, pact soil. Just right for the desert I live in. Maybe I'll let it grow, as long as it leaves my intentional well alone.
