Benincasa hispida, thewax gourd,[4][5] also calledash gourd,[6]white gourd,winter gourd,winter melon,tallow gourd,ash pumpkin,[6]dongah[7] orChinese preserving melon,[6] is a species ofvine.
The wax gourd is native toSouth andSoutheast Asia. It is grown, especially in Asia, for its very largefruit, eaten as avegetable when mature. One variety of the plant, calledchi qua (Benincasa hispida var.chieh-qua), is commonly used in Asian cuisine.[8]
The plant grows thick vines with coarse and hairy stems. It has large, rough leaves with a width between 10–30 centimetres (4–12 in) long.[9][10]
In early summer from June to September, golden yellow flowers form in the leaf axils.[11]
After they are pollinated, they bear obloid fruit 50–60 cm (20–24 in) long and 10–25 cm wide. They typically weigh 5–10 kg,[12] with weights of up to 34.5 kg recorded.[13] The young fruit are covered with soft fuzzy hairs which eventually disappear[10] and develop a waxy coating that gives the fruit ashelf life of up to a year.[14] The fruit has thick flesh that is sweet, crisp and juicy; it has white or yellow seeds.[10]
The name "winter melon" that is sometimes given to this plant is based on the Chinese namedōngguā (冬瓜); however, thecharacter瓜 (guā) can also mean "gourd" or "squash".[15] It is likely that the name "melon" is given because this gourd is sometimes candied or made into a sweet tea.
The name "wax gourd" comes from thewax coating in the fruit's skin.[14]
It is grown in well-drainedloam and sandy soils in warm, mild climates, and will not tolerate frosts. It is grown in riverbeds orfurrows, and needs constantirrigation during the growing season.[11]
The fruit, seeds, buds and young leaves can be eaten cooked, resemblingpumpkin orzucchini.[17] The gourd can be stored for many months, much likewinter squash.
Ash gourds of the Indian subcontinent have a white coating with a rough texture (hence the name ash gourd). Southeast Asian varieties have a smooth waxy texture. It is one of the few vegetables available during winter in areas ofdeciduousvegetation. In India, the wax gourd is recognized for its medicinal properties in theAyurvedic system of medicine.[16] It also has significance in spiritual traditions ofIndia andYoga, where it is identified as a great source ofprana.[18]
