Botanical illustration of Foxglove
Biennial · Digitalis purpurea

The bumblebee cathedral. Biennial rhythm confuses beginners: plant two years running, then it's a permanent self-sowing colony. Its toxicity is real — it's also heart medicine's origin.

Questions

Foxglove questions, answered straight.

Do deer eat foxglove?

Rarely — foxglove is considered deer-resistant, which makes it one of the safer unfenced choices in deer country. Hungry deer in a hard winter test every rule, but it's a low-risk pick.

Is foxglove safe for kids and pets?

No — treat it as toxic if eaten. ALL PARTS HIGHLY TOXIC (digitalis) — respect it, site it away from kids/pets/veg beds Site it accordingly if children or pets roam the garden. This is general reference, not medical or veterinary advice — call a vet or poison control if something has actually been eaten.
