Indus has the meaning of love, because in ancient times it was said that Indus was a male tree and Tung was a female tree. Sycamore trees grow old together, live and die together. Sycamore trees have tall and straight branches and deep roots, which have become a symbol of loyal love. In addition, buttonwood has noble quality, which means loneliness and sadness. The buttonwood tree symbolizes noble and beautiful character in ancient poetry, and it is also a lonely and sad image in the poet's works.
Platanus acerifolia is very fond of light and needs acidic or neutral and calcareous soil with good ground drainage and deep moisture. Buttonwood is cold-resistant, drought-resistant, barren-resistant, avoiding waterlogging, depression, waterlogging and grass shortage, and its bark is not resistant to the scorching sun. Indus is mostly cultivated artificially, easy to survive and resistant to pruning, and can be widely planted as a greening tree species.
