Muscari – Grape Hyacinth

Grape Hyacinth is one of the first spring flowers and has a great fragrance. The first time you plant them should be in November. The plants naturalize (meaning that the next year’s flowers are the same).

Severe poisoning from hyacinth or tulip poisoning is often seen when dogs dig up freshly planted bulbs or having access to a large bag of them. When the plant parts or bulbs are chewed or ingested, it can result in tissue irritation to the mouth and esophagus.
