This is a beautiful tree from the Channel Islands of California. It is used in the American States as a screen tree, like the blue gum (Eucalyptus globulus). Unlike the Australian tree Lyonothamnus is native there and not invasive.
The trees bear elegant fern-like foliage, with smooth-edged leaves not divided into any leaflets or segments. The flowers are white clusters extending out of the foliage. Unfortunately they don’t appear until the tree is around 10 years old.
Another favourite characteristic is the unique presentation of the bark, which is vividly smooth red-brown but somehow hidden by long grey strips. In autumn you can pull off the peeling bark to reveal the beautiful colours beneath.
Like many other Californian plants, Lyonothamnus is fast growing but not very long-lived. It is also rather tolerant, which makes it a good choice for contemporary, urban planning schemes where the supply of water is limited. It is also a good choice for coastal conditions.
