hardy and rare Eucalyptus parvula seeds
Eucalyptus parivfolia belongs to the Myrtaceae. In 1909 the species was first described as Eucalyptus parivfolia. In 1991 Eucalyptus parvifolia was renamed in Eucalyptus parvula because "parvifolia" was already the name of a fossil eucalyptus. Eucalyptus parvula is a rarely occurring species and endangered species. It is native to Australia and is distributed there mainly in North South Wales.
Eucalyptus parvula grows as a small tree, reaching about 10 m. Sometimes the plant has multiple stems. The treetop is beautiful round and dense. Due to that Eucalyptus parvula is often used as a hedge. Eucalyptus parvula grows very slow, about 1 m per year. Regularly cutting keeps the tree small. A small Eucalyptus parvula can be also kept as a potted plant. The young branches are beautiful reddish brown. The stem is greenish but varies a lot in color when the bark peels of the stem. The leaves of Eucalyptus parvula are smaller than in most other Eucalyptus species. Due to that the plant is often named small leaved gum. Also the Latin name parvual meaning small refers to the small size of the leaves and the low height of the whole plant. The young leaves are bluish green and ovate to elliptic. They get maximal 4 cm long and 1 cm wide. They stay long at the tree and give off the typically eucalyptus odor. The older leaves are longish. Due to the nice odor of the leaves the branches of Eucalyptus parvula are often used in flower bouquets in order to add a nice smell to the nice looking flowers. Eucalyptus leaves are furthermore the only food source of the koala. The koalas are specialized on eucalyptus and can neutralize the toxic compounds in the leaves. For other animals the eucalyptus leaves are either toxic or not worth eating because of the low nutrient content. The flowers of the small leaved eucalyptus are small and clustered in umbels that bear 7 flowers. The single flowers are white and reach 1 cm in diameter. Eucalyptus parvula does not flower regularly. In nature it flowers most intensive after a dry period to ensure surviving of the species. As pollinator of Eucalyptus parvula different insects amongst others the honey bees are listed. The fruits contain small dark brown seeds that get 1,5 mm long and do not survive very long after falling down. Eucalyptus parvula is well suited as outdoor plant in the temperate zones.
Eucalyptus parvula is a hardy Eucalyptus sppecies, it tolerates temperatures down to minus 20 °C. The small leaved gum is quite demand less and grows on many different soil types. Nevertheless one should pay attention to water Eucalyptus parvula regularly. In nature the plant occurs at moist places.
For a solid germination the seeds have to be pressed slightly into the substrate. After that they should be stored in the fridge at 4 °C for about 4-6 weeks. After that stratification germination starts just about after 3 to 6 weeks, sometimes even earlier, at a temperature of 23°C. The substrate should be kept moist throughout the cultivation. The seeds need in addition light to germinate. Therefore the seeds should not be pressed deeper into the substrate after stratification to make sure that light reaches the seeds.
