Arum pictum: Mystery and Drama for the Fall Garden

By Angela Carson (Bookerc1October 13, 2011

Arums are mysterious plants. You know the type: they send up intriguing foliage in one season, perhaps an unusual flower in another season, and then, long after you've forgotten about the plant altogether, it pops up with an unusual fruit or seed head. Arum pictum, unlike other members of the arum family, makes a dramatic appearance in the autumn, just when you least expect to see it!

In my area of central Illinois, the most common arum is Arum italicum, and it is a spring woodland flower. I rarely notice it in the flowering stage, though the blooms are attractive. Rather, it is the dramatic red seed heads that appear later in the summer and fall that catch my eye! I've already had two friends present me with the red clustered seeds for identification, one in person, and one by e-mail! I initially was confused, when I began researching arum pictum, as there is actually a variety of Arum italicum that bears the name 'Pictum.'  You can find a PlantFiles entry for this plant, fascinating in its own right, here. You may be more familiar with some other members of the aroid family, such as peace lilies, calla lilies, and the wildflower known as Jack-in-the-Pulpit.  They all feature flowers formed of a spathe with a central spadix.

It can be grown successfully in the warmer zones of the United States, possibly starting at the southern end of zone 7, and more easily thriving in the warmer zones.  In researching this article, I was privileged to correspond with C.J. Addington, an educator in northern California, who grows Arum pictum in naturalized clumps in his garden.  I owe him thanks for permission to use his picture at the start of this article!

Arum pictum is a very visually attractive plant, even in the seasons prior to bloom. It is very low-growing, reaching roughly 8 to 12 inches in height, and it produces glossy, heavily veined leaves in late summer. The leaves are roughly heart-shaped, rising on short stems from a central point on the tuber.

A gardener who chooses it for its lovely foliage may receive a double shock a few weeksArum Pictum in bloom, by Matteo Paolo Tauriello later when fall rolls around. The first surprise is visual, when the gardener finds a flower rising from the leaves, made up of a cup-shaped spathe, greenish on the exterior at the base and deepening to burgundy or darkest purple toward the tip, and evenly dark purple within.  Rising from the center of the spath is an even darker central spadix. The second, less pleasant surprise is olfactory in nature, due to the odor that emanates from it. I have heard it most often compared to the smell of horse dung, though comparisons to skunk roadkill and rotting flesh are common, too.

Arum pictum seed head, by Zaragoza Isidro MartínezThe leaves persist throughout the winter, after the flower has faded. The seed head, very striking in its own right, appears later the following summer, after the leaves have died back. It appears as a central stem with a cluster of tightly grouped seed-bearing berries, which are initially bright green, and ripen to a vibrant orange-red.

As a coastal and woodland plant, it grows well in partly sunny to sunny areas, and likes rich, well-drained humus-y soil. It can be grown in a pot, which is clearly a necessity if you live in a zone that experiences frost and extended periods of cold. I wouldn't necessarily welcome this plant into my home, due to its distinctive (ahem) fragrance, but it might be an interesting specimen to visit in a well-ventilated greenhouse setting. 

 Just a note of warning: most members of the arum family are poisonous.  They can sicken pets and other animals that nibble on them, and can even cause skin irritation when unsuspecting explorers touch the foliage, blooms, and clustered berries on the seed heads.
