Beach heliotrope (scientific name: Heliotropium foertherianum) is an evergreen shrub in the family Epiphyllaceae, native to the tropical and subtropical coastal regions of Madagascar, Asia and Oceania. It grows in clusters on sandy beaches and rocky areas such as raised coral reefs. In Japan, it is native to Amami Oshima Island and the Okinawa Islands. The trunk is soft and easily broken with a well-developed cork layer. The height of the tree is 1-3 m, but some can reach 10 m. The large leaves are concentrated at the ends of the branches. The large leaves grow in clusters at the ends of branches in an alternating pattern. Its name comes from the light green color and fleshy foliage, which is velvety with dense white hairs on the front and back. In summer, it produces many small white, bell-shaped flowers in cone-shaped florets. The flowers are followed by small spherical green fruits, which turn yellow and ripen to black with time. The fruit is carried by the Kuroshio Current.
