Botanical description of Ficus elastica
General morphology
Ficus elastica It is a robust tree that can reach 30 m in height in its natural state, with a straight trunk and aerial roots that ensure its stability and additional water absorption. Young plants often have a bushier habit when grown indoors, which helps to limit their height while maintaining dense and decorative foliage.
Foliage and leaf characteristics
The leaves are large, leathery, and glossy, generally measuring between 20 and 35 cm long and 10 to 15 cm wide. They are dark green, sometimes with red or burgundy hues depending on the variety. The midribs are prominent, and the leaf blade has a smooth texture, contributing to the tree's aesthetic appeal.
Flowers and fruits
Although the tree produces flowers and fruits called figsThese elements are rarely visible outside their natural environment. The flowers are actually very small, unisexual, and clustered inside a closed structure called a syconium, which will later become the fruit. They are therefore not visible like typical flowers, as they develop inside this fleshy cavity. The figs are small, globular, and greenish, forming from these internal structures. Pollination is carried out by specific species of wasps. fig treewhich explains the rarity of fruiting in domestic crops.
Growth and development
Ficus elastica grows relatively quickly in tropical and subtropical climates, especially in humid and sunny conditions.
