Peperomia obtusifolia 'Lime' – baby rubber plant with lime-green margins


Peperomia obtusifolia 'Lime' is a compact variegated cultivar admired for its bright lime margins that frame the dark green centers of each leaf. With its upright habit and fleshy stems, this baby rubber plant rarely exceeds 30 cm in height, making it perfect for desks, shelves, or grouped plant displays. Despite the common name, it is unrelated to the true rubber tree (Ficus elastica), but shares the same glossy, leathery appearance.
 
● Growth and features of Peperomia obtusifolia 'Lime'


This cultivar forms bushy clumps on thick, succulent-like stems. The elliptic leaves are waxy and smooth, with a bold contrast: lime-green variegation around the margins and darker green tones along the midrib. Small, greenish-white flower spikes may appear, but the foliage remains the main attraction. Its compact size and colorful edge make it one of the most striking yet easy-care Peperomia cultivars.
 
● Background and naming


Peperomia obtusifolia was originally described as Piper obtusifolium by Linnaeus in 1753 and later reassigned to Peperomia by A. Dietrich. It occurs naturally in Florida, the Caribbean, Mexico, and parts of South America. The specific epithet obtusifolia means “blunt-leaved,” describing the rounded tips of the leaves. The trade name 'Lime' highlights the cultivar’s characteristic light-green margins.
