Did You Know?

The sticky stem hairs trap small insects — earning the name 'Catchfly' — but the plant is not carnivorous; it's just a defense against nectar thieves.

Royal Catchfly is endangered in several states due to prairie habitat loss, but it is surprisingly easy to grow in gardens with good drainage.

The brilliant red flowers are specifically adapted for hummingbird pollination — the tubular shape and color are invisible to most insects.
