Purple Fruits on the Vine

After autumn, akebia at the forest edge is easy to recognize: stout vines climb the trees, and from the vines hang several long purple fruits, as if someone had hung a string of small sausages in midair. The rind bears fine stripes and is stiff—it does not look edible.

Its leaves are palmate with five leaflets; the flowers are purplish brown, monoecious, blooming in spring without fanfare. The whole vine’s only signature is those few heavy purple fruits of autumn.

— Botany Notes, self-inscription —

Purple fruits hang heavy from the old vine,

and the mountain wind cracks them open one dawn.

August-Split

Mountain folk call it “August-Split”: when fully ripe, the rind splits open along the seam, revealing white pulp and a row of black seeds—only that sweet-fragrant layer of pulp is edible. Children wait all year for that one sound of splitting.

That splitting is also its way of spreading: the fruit bursts and scatters seeds; birds and beasts come to eat and carry the seeds elsewhere. A plant offers sweetness in order to hire others to do its traveling.

Akebia in Medicine

The medicinal akebia (mutong) uses the vine’s stem: it clears heat, promotes urination, and promotes lactation—a common vine medicine. Cut open, the stem is soft and spongy, with a ring of small pores across the section; the ancients read it as “free passage,” and took the meaning.

A warning is due: more than one plant has historically been sold under the name mutong, and one source from the Aristolochia family (guanmutong) contains aristolochic acid, with a well-documented kidney toxicity; it is now strictly regulated. Any medicinal use must follow a physician’s prescription—never gather and boil the vine yourself.

• How to know it: Deciduous woody vine; palmate compound leaves with five leaflets; flowers purplish brown; fruit long-elliptic, splitting lengthwise when ripe to reveal white pulp and black seeds.
• When to enjoy: Flowers April to May; fruits ripen and split August to September—its liveliest time of year.
• Caution: The source plants of akebia medicine are complex; some contain aristolochic acid with kidney toxicity—never harvest the vine for medicine on your own.

Autumn on the Pergola

Akebia vines grow vigorously with dense leaves; by summer they can cover a whole frame with shade deep enough to sit under; in autumn the fruit hangs down, and looking up from beneath the pergola you see a string of purple. As a courtyard trellis plant it both shades and shows fruit.

It also tolerates half shade and is easy to keep—as long as the soil does not waterlog, it can cover a frame in a year. In many childhood memories, those few August-Split fruits on the old wall of the family house grew just this way.
