The bark peels off in long strips from the silvery trunk. The aromatic lanceolate leaves are bluish-grey. The white flowers measure 3 cm (1.18") in diameter. They bloom from late summer to mid-autumn. The aromatic fruits are capsules in the shape of a flared cone. They are used as isolated specimens in large gardens and in public parks. It is not convenient to plant them near buildings due to the strength of their superficial roots. Eucalyptus globulus needs full sun exposure and a warm climate. It resists light and occasional frosts. The soil should be well drained and contain some organic matter; They prefer siliceous soils. Water moderately waiting for the substrate to dry. They resist a few days of drought when they are established. Fertilize with compost or manure in the fall. They do not need pruning but the dead branches can be removed at the end of winter. They are plants resistant to the usual pests and diseases. They are propagated from seeds sown in the fall or spring. These seeds can be kept for 10 years maintaining their germinative power. |
