Alkekengi

Alkekengi, also known as the Chinese lantern, Japanese lantern, bladder cherry, or winter cherry, is a flowering plant belonging to the nightshade family (Solanaceae). It is characterized by its distinctive inflated, papery calyx that resembles a lantern and encloses a small, round fruit.

Botanical Description

Alkekengi species are herbaceous perennials, typically growing to a height of 40-60 cm. They feature ovate, pointed leaves. The flowers are small, white, and inconspicuous. However, the plant's most notable feature is its inflated calyx, which starts out green and matures to a bright orange or red color, creating a striking visual display in autumn. Inside the calyx, a small red or orange berry develops.

Distribution and Habitat

Alkekengi is native to regions spanning from Southern Europe and East Asia. It is often found in woodlands, thickets, and along roadsides. It has also been introduced to other parts of the world, where it sometimes naturalizes.

Cultivation and Uses

Alkekengi is cultivated as an ornamental plant for its attractive calyces. It is popular in dried flower arrangements and as a decorative feature in gardens. The berries are edible, though they have a somewhat bitter taste and should be consumed in moderation. Traditionally, the plant has also been used in herbal medicine, though caution is advised, as some parts of the plant contain solanine, a toxic alkaloid. The dried calyces retain their color for a long time, making them valuable for crafting.

Toxicity

While the berries are considered edible in small quantities, other parts of the Alkekengi plant, especially the leaves and unripe fruit, contain solanine and are potentially toxic. Ingestion of large quantities can cause gastrointestinal distress. It is generally recommended to exercise caution when consuming any part of the plant.

Species within the Genus

The genus Physalis contains several species, with Physalis alkekengi being the most well-known and commonly referred to as Alkekengi. Other species within the genus have similar inflated calyces and are sometimes confused with Physalis alkekengi.
