Philydrum lanuginosum

The spikes successively open many, attractive, fine yellow flowers. Long, pointed, green and woolly bracts enclose each bud. As the spike grows, each successively mature bud’s bract reflexes, opening the flower inside and subtending it, holding its delicate yellow petals on display. Each flower has two outer showy petals which look like open yellow mouths, hence the common name frogsmouth.

Philydrum is a nice addition to a bog garden or pond as it offers both colour and height, and also provides protection for frogs and fish. If the conditions are suitable, it will self-seed around your pond.
