The story

Partridge pea is an annual legume of sandy roadsides and old fields. It keeps a second nectar supply in tiny glands on its leaf stalks, which recruits ants and wasps as bodyguards. Touch a leaf and it folds slowly shut.

Planting

Sow scratched seed in fall or early spring on bare, sunny, poor soil.

Growing

None. It reseeds itself each year where the soil stays open.

Harvest and use

Buzz pollination by bumblebees, food for sulphur butterfly caterpillars, hard seed for quail through winter, and nitrogen for the soil.

What to watch for

It can crowd out small neighbors in a new planting, then settles down.
