Confusion Risk

The following plants look similar and may be confused:

Silver Squill Ledebouria socialis

Has similarly patterned silver-green striped oval leaves; key difference is silver squill grows from toxic bulbs, while Peperomia sandersii has no bulb structure and is non-toxic

Pinstripe Calathea Calathea ornata

Features similarly shaped striped oval leaves; key difference is its stripes are thin pink/white pinstripes, rather than the wide watermelon-like green and silver bands of Peperomia sandersii
