Ficus eximia is a deciduous tree with a dense, rounded, low crown; it can grow 15 - 30 metres tall. The short bole is very grooved, it can be 80 - 160cm in diameter[
The tree is sometimes harvested from the wild for its low value wood. It can be used as a pioneer when restoring native woodland and, providing a good shade, it can be used in landscaping[
S. America - southern, central, eastern northeastern and northern Brazil.
A pioneer species of open places and secondary forest growth, found in a variety of habitats, but mainly in the Atlantic rainforest, favouring deep, fertile, moist soils[

Grows best in a sunny position[
]. Prefers a deep, fertile, moist soil[
A moderately fast-growing plant when young, able to reach a height of 2 metres within 2 years from seed[
Fig trees have a unique form of fertilization, each species relying on a single, highly specialized species of wasp that is itself totaly dependant upon that fig species in order to breed. The trees produce three types of flower; male, a long-styled female and a short-styled female flower, often called the gall flower. All three types of flower are contained within the structure we usually think of as the fruit.
The female fig wasp enters a fig and lays its eggs on the short styled female flowers while pollinating the long styled female flowers. Wingless male fig wasps emerge first, inseminate the emerging females and then bore exit tunnels out of the fig for the winged females. Females emerge, collect pollen from the male flowers and fly off in search of figs whose female flowers are receptive. In order to support a population of its pollinator, individuals of a Ficus spp. must flower asynchronously. A population must exceed a critical minimum size to ensure that at any time of the year at least some plants have overlap of emmission and reception of fig wasps. Without this temporal overlap the short-lived pollinator wasps will go locally extinct[
A fast-growing tree providing food for the native fauna, it can be grown as a pioneer when restoring native woodland[
The wood is coarse-textured, straight-grained, light in weight, easy to cut, with poor mechanical properties and very susceptible to termites and rot. It is only used for low value items such as the filling in doors and panels[
Seed - best sown as soon as it is ripe in a partially shaded position in a nursery seedbed. The seed is very small and an easy way of obtaining it from the tree is to collect the fruits and place them in a plastic bag then leave them until the fruit is partially decomposed. Then mix the fruit with some water to make a suspension of seeds and pulp - this suspension can be sown directly onto the seedbed. A low germination rate can be expected, with the seed sprouting within 20 - 40 days[
