Chinese Peking Tendan

The morning glory was introduced to Japan by way of China. Dr. H. Kihara collected this strain blooming at Tendan Park, in a Beijing suburb, in 1938.
The cotyledons are green, and the hypocotyl has a tinge of light red. There are epidermal hairs on the hypocotyls and cotyledonary petioles. The leaf is three-pointed and is triangular due to a shallow cut in the interval part of the leaf lobes. In comparison with other strains, a leaf with a short triangle will be small and the plant will lack vigor. This strain blooms early, probably because it has adapted to high latitudes. In Shizuoka-city, for example, blooms appear from the end of June to the beginning of July. The flower withers up very rapidly. The corolla is light blue, the flower tube is white, and the flower diameter is ca. 5 cm. White epidermal hairs grow thick to the sepal. One flower is generally observed per peduncle, but there can be two flowers per peduncle.
