Description
editClusia rosea is a tree native to the Caribbean, including the Bahamas, Hispaniola (such as in Los Haitises National Park), Cuba, Puerto Rico, and Florida.[7][8]
It is a hemiepiphyte; that is, it grows as an epiphyte on rocks or other trees at the start of its life and behaving like a strangler fig as it gets larger. Like a strangler fig, it successfully competes for light by outgrowing, overtopping and "strangling" its host tree with its many aerial roots.[9][7][8][10]These roots are among the fastest growing known; up to 12 inches (30 cm) in 24 hours.[11]
The petals are pink to white. The thin upper leaf tissue registers 'writing' giving it the common name "autograph tree". The tree produces a fleshy, light green toxic fruit; once the fruit splits, the seeds are consumed by birds and other wildlife. Clusia species are normally dioecious, but in C. rosea, there are pistillate (female) individuals only, and seeds are formed through agamospermy.
Cultivation
editThis plant is cultivated as an ornamental plant, for its flowers, foliage, and fruit. It is planted in gardens as a fruiting and ornamental tree in sub-tropical climates, and used as a houseplant in many climates.[12]

Invasiveness
editClusia rosea has become a great threat to Sri Lanka, Hawaii, and many other tropical countries as an invasive plant.
In Sri Lanka it is spreading rapidly on the mountains of the central hill country. It especially grows on rocks and rock outcrops where it forms dense thickets. Being a hemiepiphyte that resembles a strangling fig, it also sprouts on branches and trunks of native trees and rapidly overgrows and strangles them. It therefore poses a great threat to what little remains of the native submontane forests, and the unique native vegetation around rock outcrops, such as on the Hantana mountain range near Kandy. It is known as Gal Goraka (ගල් ගොරක) or Gal Idda (ගල් ඉද්ද) in Sinhalese.[13][14][15]
It is one of Hawaii's most invasive plants and grows in forests and open, disturbed areas in low elevations. It is spread by birds which eat its fruits.[7][8][16]
Uses
editThe leaves were used to make playing cards in the West Indies. Some sign their autographs on the leaves and watch them grow.[17]
In Puerto Rico, in the past, parts of the plant were used to make game balls, to make tar and for firewood.[4]
