Host plants for the henry's elfin

The garden plants whose leaves henry's elfin caterpillars eat, and a bed the planner designed around them.

The henry's elfin (Callophrys henrici) is a butterfly. Like every butterfly and moth, it can lay its eggs only on the plants its caterpillars can eat, its host plants. A garden with nectar flowers feeds the adults as they pass; a garden with host plants is where the next generation is raised.

These eight garden plants are recorded by NC State as hosts for its caterpillars. Expect chewed leaves: that is the point. Do not spray, and leave fallen leaves under the plants in winter, where many caterpillars and pupae spend it.

8 plants: 8 shrubs.

Planned as a naturalistic planting: low grasses and groundcovers, the matrix, make up 44% of the planted ground. The back corners are held by inkberry and switchgrass 'Prairie Sky', the tallest plants on the plan. Creeping phlox 'Emerald Blue' and leadwort finish the front edge.

The planner's own design check: 8 Excellent, 6 Good, 2 Satisfactory, 1 Needs revision. Its weakest point is foliage: Inkberry, inkberry 'Gem Box' and inkberry 'Shamrock' are grown for their leaves, and cover 37% of the planted ground. The Foliage control above the plan asks for about 10%.
