The Ficus Elastica ruby is known for its ruby-pink leaves, which are a result of its unique variegation, making it a showstopper in any space. It prefers bright, indirect light to maintain its vibrant variegation. Allow the top inch of soil to dry before watering, and ensure good drainage. It thrives in warm temperatures above 60F (16C) and benefits from occasional misting for added humidity. Fertilize monthly during spring and summer with a general-purpose houseplant fertilizer.
