Description

The state flower of Connecticut, mountain laurel is an evergreen shrub that produces spectacular clusters of white to pink cup-shaped flowers in mid-June. The flowers have an ingenious catapult mechanism: bent stamens are tucked into pockets in the corolla and spring outward when triggered by a visiting bee, dusting the insect with pollen. It forms dense thickets on rocky, acidic slopes.

Identification tips

  • 1Cup-shaped flowers white to pink, often with a ring of dark pink spots inside
  • 2Stamens bent like spring-loaded catapults, tucked into corolla pockets
  • 3Leathery, glossy, dark green evergreen leaves, alternate, elliptical
  • 4Gnarled, twisting trunks and branches on older specimens
  • 5Brown seed capsules persist through winter in star-shaped clusters

Specimen & preservation notes

Press a flowering branch with a few flower clusters and several leaves. Flowers are thick and fleshy — slice some in half longitudinally to show the stamen catapult mechanism. Allow extra drying time (3–4 weeks) for the leathery leaves.
