Clusia rosea – Autograph Tree The Autograph tree was brought into Hawaii as an ornamental plant. The tree has an apple sized green fruit. As the fruit dries, it opens at one end and disperses tiny red seeds. The fruit drops to the ground and turns into a hard star shape that is quite attractive. The Autograph tree gets its common name (also called the Signature Tree) because of the leaves. Each leaf is fairly large, 5 to 8 inches, oval, thick and sturdy. You can scratch the leaf with a sharp object and it will remove the dark green outer layer and reveal a light green inner layer. People write messages, their name, love notes and other types of graffiti into the leaves. The messages stay as long as the leaf is attached to the tree, often months. The leaves have also been used in the past as playing cards. The flowers of the tree are sometimes used in floral arrangements and a sticky sap found in the seeds has been used as a weatherproof caulking abd is considered poisonous.. The tree is unfortunately extremely invasive. The seeds are spread by birds and the tree can start just about anywhere. It is not unusual to see a Signature Tree growing out of the middle of another tree. The seeds will sprout and drop long roots or the seeds will be eaten by birds. Eventually the tree will kill its host and replace it. It is nearly impossible to eradicate the tree - as there is so much of it on the islands, however future planting should be discouraged.
