Are my houseplants poisonous to dogs & cats?
Hi there! I have acquired 2 plants and I don’t want to bring them in the house until I know if they are hazardous to cats or dogs…I have a ‘Popcorn Cassia’ (or Cassia Didymobotrya) and a Moses in the Cradle Plant (tradescantia spathacea)…thank you for your time.
Hi,
Popcorn Cassia (Cassia didymobotrya) is a unique and beautiful plant, though I have only seen it grown as an outdoor plant not a houseplant. When the leaves of the Popcorn Cassia (sometimes called Peanut Butter Cassia) are crushed it emits the scent of buttered popcorn. It is a poisonous plant and will cause problems if ingested by humans or pets.
Moses in the Cradle plants are poisonous house plants with a #3 toxicity level. The sap of a Moses in the Cradle plant causes severe pain in the mouth if eaten and minor skin irritations that last a few minutes.

Tradescantia spathacea
