Allium

Allium giganteum

Dramatic globe-shaped heads on tall stems. Architectural and deer-proof.

Dangerous to cats

Toxic to cats and dogs, which is worth knowing because the same plants are a kitchen staple for us. Onions, garlic and chives damage a pet's red blood cells, and the damage builds up over repeated small nibbles rather than needing one big meal. Keep the bulbs and any cut stems out of reach.
