Hollyhock
Alcea rosea
Malvaceae
The tall spire against a wall — a biennial or short-lived perennial that makes a cottage look settled in one season of waiting.
Cottage hollyhock. Related to marshmallow and okra; flowers are sometimes used in tea, but rust and spray make this a decorative plate first.

Lookalikes
- Foxglove — Two cottage spires. One is a cardiac drug. The other is a mallow you may not want to eat either, but it will not stop a heart in a cup.
- Datura — Trumpet flowers in a cottage bed. Datura is a tropane nightshade. Hollyhock is a mallow. Children have eaten the wrong seed pod.
Lore
Holy hoc in Middle English — a mallow associated with the Crusades in the usual unreliable way. Japanese horticulture bred the dark forms. American alleys still have the pink ones no one planted on purpose.
