Ficus altissima

Ficus altissima – Majestic Evergreen Fig

Ficus altissima Blume is a large, evergreen fig tree native to southeastern Asia. It often begins life as an epiphyte, growing on other trees – especially palms – before sending down aerial roots that eventually reach the ground. Over time, these roots can encircle and replace the host tree, a characteristic shared with other figs. In some cases, it also grows as a lithophyte, establishing itself on rock walls, buildings, and even bridges. Due to its extensive root system and immense size, it is unsuitable as a street or landscape tree, but when cultivated in a pot, it makes an attractive houseplant.
