Halocarpus bidwillii (Bog Pine)


Michael's Opinion

A scruffy, typically wetland shrub with little ornamental value. These plants can grow in masses, and can spread naturally with lower horizontal branches taking root. The seeds have an interesting appearance, small green to brown cones with a unique white to yellow aril.
