Long absent from American ornamental gardens, mandrake (Mandragora officinarum), also called Satan’s apple, is making a comeback, thanks in part to the Harry Potter books and movies. Mandrake plants bloom in spring with lovely blue and white blossoms, and in late summer the plants produce attractive (but inedible) red-orange berries. Keep reading for more mandrake information.
What is the Mandrake Plant?
Wrinkled and crispy mandrake foliage might remind you of tobacco leaves. They grow up to 16 inches long, but lie flat against the ground, so the plant only reaches a height of 2 to 6 inches. In spring, flowers bloom at the center of the plant. Berries appear in late summer.
Mandrake roots can grow up to 4 feet long and sometimes bear a remarkable resemblance to a human
Like many members of the Nightshade family, mandrake is poisonous. It should only be used under professional supervision.
It takes about two years for the plant to become established and set fruit. During that time, keep the soil well watered and feed the plants annually with a shovelful of compost.
Never plant mandrake in areas where children play or in food gardens where it may be mistaken for an edible plant. The front of perennial borders and rock or alpine gardens are the best places for mandrake in the garden. In containers, the plants remain small and never produce fruit.
Propagate mandrake from offsets or seeds, or by dividing the tubers. Collect seeds from overripe berries in fall. Plant the seeds in containers where they can be protected from winter weather. Transplant them into the garden after two years.
