Sweetheart Hoya
Hoya kerrii
Non-toxic to cats and dogs
The single heart-shaped leaf sold at Valentine's is usually a rooted cutting with no growing point, so it stays one leaf. A full plant with a vine will trail for years.

Pet-safety information is a general guide from the ASPCA's toxic-plant database and covers cats and dogs only. "If eaten" summarises the symptoms ASPCA lists for that plant; how an animal actually reacts depends on how much it ate and on the animal. It isn't exhaustive, isn't veterinary advice, and individual animals vary — never rely on it as the sole basis for a decision about your pet. If you think your pet has eaten a harmful plant, contact a vet immediately.

The same interval the Sabz app schedules reminders from. In autumn and winter the app stretches it; see houseplants in autumn.

- Shrivelled leaf — underwatering, though it stores a lot
- Black mushy base — overwatered — Root rot →
