Datura for a mallow

Trumpet flowers in a cottage bed. Datura is a tropane nightshade. Hollyhock is a mallow. Children have eaten the wrong seed pod.

Datura has a spiny capsule and a nightshade smell; flowers are funnel trumpets, often upward or nodding, with a simple calyx. Hollyhock is a column of mallow discs on a tall wand. Do not nibble an ornamental pod.
