Eucalyptus macrocarpa is a plant from Western Australia and is much valued for its huge dark pinky red flowers and grey- green foliage in floral art work. The gum nuts measure about 3 inches (75mm) across and are also very decorative. When they split to release the seeds, an opening is left which will hold a small candle. With the base leveled off these make a great Christmas decoration. Eucalyptus macrocarpa is well worth trying for the flower display. It would make good large pot plants if you cannot give it the conditions that is needed. Seeds germinate easily. Keep seeds in fridge a few weeks prior to planting to aid in faster germination.
