Acacia pravissima is a lesser-known Mimosa. The leaf is very recognizable due to its triangular shape. The leaves droop somewhat, giving it a weeping form in mature specimens. This Acacia remains evergreen and is perhaps the most winter-hardy of all Acacias.
Like virtually all Mimosas, this Acacia also originates from Australia. However, this species has its origins on Australia's coldest island: Tasmania. Temperatures here regularly drop below zero in winter. Due to the heavy rain and the "harsh" climate, this Acacia had to adapt well to these conditions.
The flowers are round, light yellow, fluffy spheres of approximately 1-1.5 cm in diameter that grow in fragrant flower clusters. The slightly sweet scent emitted by the flowering plant is pleasant. Spent flowers form elongated green pods up to 20-25 cm long.
The location is a sunny or semi-shaded spot on well-moisture-retentive soil.
The tree can grow up to 2.5 meters tall and will then assume its characteristic weeping form.
If desired, this mimosa can also be kept very well as a container plant.
The growth habit can also be kept as a shrub by means of pruning.
To overwinter as a container plant, a frost-free location is sufficient; the roots must not freeze in the container.
The Tasmanian Acacia blooms very early in spring; the buds are usually visible as early as November/December, and it will bloom around March. Therefore, be sure not to prune during this period. It is best to do this in the summer months when it still has sufficient time to produce new shoots, as the plant flowers on its newest leaves.
Winter hardiness zone 8a (-12ºC).
