Red, blue, purple. Their trumpet-shaped blooms are so pure that they give off a feeling of purity. In ancient China, Asagao seeds were treasured as a valuable medicine. When a man received a Asagao as a gift, he would pull an ox to show his gratitude, hence the name "Kengyu" (Altair). Morning glories bloom around Tanabata. Since Hikoboshi is also called Hikoboshi, they have come to be loved by the nickname "Kengyu-hana" (Altair Flower) since some time ago. People pray for a good relationship based on the legend that Hikoboshi and Orihime meet only once a year, and the sight of the Asagao, which grows its vines, twines around each other, and blooms in abundance, brings prayers for a prosperous future.
