he Season for Madrona
madrone tree sports a different wondrous shape from multi-stem octopus trees that have re-sprouted after a fire to grand “girthy” older beauties. The leaves are sclerophyllous – thick and sturdy broadleaf leaves that conserve water during hot summers. Second year leaves drop off during the summer, adding yellows to the bark chip forest floor, while younger leaves provide a canopy of green light all year-round. The leaves also provide a holiday-style contrast to the red pitted berries that droop from branches in the fall.
