Boasting the largest single seed capsule of any eucalypt, E. macrocarpa is also one of the types of eucalyptus koalas don’t eat. It is a mallee type—developing into a huge bush rather than a tall tree. The plant grows from a lignotuber, which allows it to regenerate from the ground. Eucalyptus blooms are different from most flowers—they have no petals, just exposed tufts of lush stamens. Depending on the type of eucalypt, the stamens may be red, yellow, orange, or white.
Before and after: from a rather prickly looking pod comes a flush of fluffy stamens.
Cap off to the future! As the stamens reach their full development, the swelling pushes the pod cap off. Then the stamens spread wide to give pollinators plenty of reasons to stop by.
Eucalpytus seed pods are commonly called gum nuts. They may remain on the tree for quite a long time. When the stem becomes brittle and breaks off, the gum nut falls to the ground, and the resulting impact sets the seeds free.
From elongated “spike balls” to dangling cups to a compact cluster like this one, eucalypt pods display a diverse range of appearance.
