Rubber Plant-Ficus Elastica. The rubber plant (ficus elastica) is another tree like species with four popular varieties. The most popular is the decora which has large green oval shaped leaves and the robusta which has larger leaves.
When growing ficus indoors, it is important to maintain a relatively high humidity around the plant. Regular misting or setting the ficus tree on a pebble tray filled with water is a great way to increase their humidity, but keep in mind that while they like high humidity, they do not like overly wet roots.right, direct light may result in scalding of the leaves and leaf loss. Ficus trees also cannot tolerate low temperatures or drafts. They need to be kept in temperatures above 60 F. (16 C.) and actually prefer temperatures above 70 F. (21 C.).
