Silk Gourd
Latin:
Luffa cylindrica
Origin:
Silk gourd is the fresh tender fruit of Luffa cylindrica (L.) Roem. (smooth-fruited luffa), the same as Luffa aegyptiaca Mill., and Luffa acutangula (L.) Roxb. (angled luffa), belonging to the marrow (Cucurbitaceae) family. Luffa is the genus name for this group of gourds. It is a warm season, cold sensitive genus originating in India. Both species now grow throughout the tropics.

Both luffas are valued as food items in the East, but are seldom eaten in the West. Most gardeners in the West grow them for their fibrous interior, which is useful as a rough cloth or sponge for cleaning and scouring. The two species are somewhat similar in appearance. Both are vigorous, climbing, annual vines with several lobed cucumber-like leaves. When crushed, the leaves give off a rank odor.
Both male and female flowers occur on the plant with a much greater number of male flowers. The rather large male flowers are bright yellow and occur in clusters. The female flowers are solitary and have the tiny slender ovary attached. Angled luffa flowers appear later in the day than the smooth type and stay open through the night. Bees pollinate the flowers. Being cold sensitive, luffas should be grown during the warm season. Leaves are covered with short stiff hairs.

Smooth luffa fruits are shaped like cucumbers but are larger, 0.3-0.6 m in length and 8-12 cm thick. The exterior is green, sometimes mottled, and smooth with longitudinal lines. Fruits of the angled luffa are characterized by sharp, elevated ridges running the length of the pods. The interiors of both are cucumber-like when immature, but quickly develop a network of fibers surrounding a large number of flat blackish seeds. Smooth luffa seeds are a bit more narrow and have a pitted appearance.
