Asparagus (Asparagus officinalis)
The edible portion is the above-ground stem or "spear" which grows from a below-ground crown. They have overlapping scales that are triangular and the tips are sometimes purple. Spears are harvested when they are immature and tender. Foliage is light green, fern-like and soft to the touch. Small fruits are round and berry-like. When young, they are green, turning red when mature; then black when fully ripened.
