Peperomia obtusifolia 'USA' – variegated baby rubber plant


Peperomia obtusifolia 'USA' is a variegated cultivar of the baby rubber plant, a compact species native to the Caribbean and tropical Americas. This upright grower forms thick, succulent-like stems and fleshy, glossy leaves with irregular cream-yellow margins that look hand-painted. Despite its common name, the baby rubber plant is unrelated to the true rubber tree (Ficus elastica) but shares the same glossy, leathery look that makes it popular indoors.
 
● Growth and appearance of Peperomia obtusifolia 'USA'


This cultivar develops a bushy, upright habit, typically reaching 25 – 30 cm when grown indoors. Leaves are elliptic, dark green in the center, and bordered with uneven cream and yellow variegation, giving each plant a unique painterly pattern. Under favorable conditions, slender greenish-white flower spikes may appear, though the foliage is the main feature.
 
● Origin and naming background


Peperomia obtusifolia was first described as Piper obtusifolium by Linnaeus in 1753 and later transferred to Peperomia by A. Dietrich. The species occurs naturally in Florida, the Caribbean, Mexico, and South America. The cultivar name 'USA' reflects its spread through American horticultural trade. Common names include “baby rubber plant” and “blunt-leaved peperomia.”

● Etymology of Peperomia obtusifolia


The genus name Peperomia combines the Greek peperi (“pepper”) and homoios (“resembling”), as the plants are related to true pepper (Piper nigrum). The species epithet obtusifolia means “blunt-leaved,” referencing the rounded tips of the foliage.
