Sweet William

Dianthus barbatus

Dense flat clusters in zoned bicolors with a sweet clove fragrance. Old-fashioned cottage charm that returns reliably.

Dangerous to cats

Mildly toxic to cats and dogs. Chewing it can cause vomiting, and contact can irritate skin, which is worth remembering when a bunch comes indoors.
