Dieffenbachia vs Peperomia — frequently asked questions
Is Dieffenbachia the same as Peperomia?
No — Dieffenbachia is Dieffenbachia seguine and Peperomia is Peperomia obtusifolia. Two bushy, variegated tabletop foliage plants — one is a calcium-oxalate 'dumb cane', the other is a genuinely pet-safe look-alike.

Which is easier to care for, dieffenbachia or peperomia?
Easier comes down to your conditions. Dieffenbachia wants medium indirect light (a couple of metres from a window) and to be watered when the top 3 cm of soil is dry, every 7-10 days. Peperomia wants medium indirect light (a couple of metres from a window) and watering when the soil is almost fully dry, every 10-14 days.
