In spring and summer, your healthy, actively growing Ficus elastica, or rubber tree, may send up a red sheath that appears to be a bud. While the rubber tree can produce a type of inflorescence, this is rare for plants grown indoors. So, if it’s not a bud, what other purpose could that sheath possibly serve?
Rubber tree is often chosen as a houseplant, with its structured branches, colorful varieties, and big, glossy leaves lending interest to modern decor. This tropical tree can reach towering heights of over 100 feet in the wild, but with a little pruning and some mottled sunlight, these robust plants can thrive indoors.
