Japanese chestnut + Towel gourd
Japanese Chestnut (Castanea crenata) is a species of chestnut originally native to Japan and South Korea. It is a small to medium-sized deciduous tree growing to 10-15 m tall. The leaves are similar to those of the Sweet Chestnut, though usually a little smaller, 8-19 cm long and 3-5 cm broad. The flowers of both sexes are borne in 7-20 cm long, upright catkins, the male flowers in the upper part and female flowers in the lower part. They appear in summer, and by autumn, the female flowers develop into spiny cupules containing 3-7 brownish nuts that are shed during October.

Luffa is a genus of tropical and subtropical vines classified in the cucumber family. In everyday non-technical usage the name, also spelled loofah, usually refers to the fruit of the two species Luffa aegyptiaca and Luffa acutangula. The fruit of these species is cultivated and eaten as a vegetable. The fruit must be harvested at a young stage of development to be edible. The vegetable is popular in China and southeast Asia. When the fruit is fully ripened it is very fibrous. The fully developed fruit is the source of the loofah scrubbing sponge which is used in bathrooms and kitchens as a sponge tool. Luffa are not frost-hardy, and require 150 to 200 warm days to mature.
