Fast-growing, evergreen, hardwood tree <20m tall. Bark can be smooth, peeling or fibrous. Most eucalypts shed their lower branches giving tall straight trunks. Blue-green, stalkless, heart-shaped juvenile leaves in opposite pairs; adult leaves green, sickle shaped, have short stalks & hang vertically, reducing water loss. Adult leaves also contain aromatic, volatile oil, making them a fire hazard. Flowers & fruits can be a wide variety of colours & occur in heads with numerous stamens similar to those of pöhutukawa.
Shrubland, lowland areas. Not widespread in the wild. Commonly used for shelterbelts, firewood, & as timber plantation spp. as will self-coppice.
Grows readily from seed locally dispersed by gravity.
Inhibits growth of other plants in vicinity due to release of toxins into the soil via leaves, bark & insect frass.
Avoid fire at all times. Plant tall, shady trees to inhibit germination. Create wide shelterbelt where seedlings occur adjacent to eucalypt plantations. Discourage germination (& encourage native spp.) by maintaining deep humus layer. Exclude livestock. Discontinue surface drainage where this has been installed.
1. Pull out small plants.
2. Cut & stump paint (5g metsulfuron/1L or 100ml Tordon BK/1L).
3. Cut or drill hole every 50mm around stem diameter & fill each cut or hole with 1g metsulfuron (dissolved in approx 50ml water) or 10ml Tordon BK. Can be done year round.
