The differences that matter

Pet safety

This is the difference that matters most. Ripple peperomia is listed non-toxic to cats and dogs; Coffee plant is toxic (caffeine). If the two are sold under the same name, a mislabelled plant is a genuine risk in a house with animals.

Mature size

Coffee plant reaches about 72 inches; Ripple peperomia tops out near 12. Buying the wrong one for a shelf means rehoming it in a year.

Light

Ripple peperomia tolerates low light; Coffee plant needs medium as a floor. Put the second in the first's spot and it stretches and declines.

Difficulty

Ripple peperomia scores 1 of 5, Coffee plant scores 3. easy to grow as foliage and effectively impossible to crop indoors — it needs three to four years and specific conditions to fruit, and one plant yields a few grams of beans. Buy it as a glossy shrub.

Habit

Coffee plant grows upright; Ripple peperomia grows clumping. That decides where each one physically works.

Not even related

Coffee plant is Rubiaceae, Ripple peperomia is Piperaceae. They share a shop label and nothing else — different families, different continents, different care.
