Coast redwoods are planted around Eugene, and a small grove was planted at Mt. Pisgah when the arboretum was created. Redwoods are wind-pollinated, and the male cones release pollen in winter or early spring. Check out this slow-motion video of the pollen cloud released from the male cones. They are like piñatas breaking open sprinkling a golden treasure out into the world.
I hope you are enjoying the cold, sunny weather.
