Safety status
What this means for your dog
Summer hyacinth (Galtonia, not a true Hyacinthus) is listed by the ASPCA as non-toxic to dogs. The garden hyacinth (Hyacinthus orientalis) bulb that's toxic to dogs is a different plant — Galtonia is the safe look-alike. A dog that digs up and chews a bulb may have a brief GI upset from the fiber, but no poisoning risk on file.
