Miscolobium nigrum Allem
Miscolobium violaceum Vogel
Dalbergia miscolobium is a slow-growing, small, evergreen tree with an open crown growing 8 - 16 metres tall. The bole can have a diameter of 30 - 50cm[
The tree yields a good quality, ornamental timber. It is often harvested from the wild for local use and export. A very ornamental tree, valued particularly for its light, bluish-green foliage, it is very suitable for general landscaping[
S. America - Paraguay, Brazil.
Savannah, often in open, secondary growth areas where it can grow in large groups[
|Other Uses Rating||
|Cultivation Status||Ornamental, Wild
A plant of tropical savannah areas, usually found at elevations above 800 metres but sometimes descending to 200 metres.
Requires a sunny position[
]. Found in well-drained, sandy soils in the wild[
Newly planted young plants are slow to establish and grow away very slowly[
This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[
The wood is moderately heavy, hard, decorative, of high natural durability[
]. A fine quality wood, it is used for furniture and indoor finishing in houses[
Seed - best sown as soon as it is ripe[
]. The seeds can be sown whilst still in their pods, though this will lead to a percentage of twisted and imperfect seedlings[
]. The seeds should be sown into individual containers since the seedlings are intolerant of root disturbance. Cover with 5mm soil and place the containers in a semi-shaded position. Germination rates are usually low, sprouting occurring within 30 - 40 days. Seedlings grow away slowly, and will be ready to plant out after 7 - 8 months[
Like many species within the family Fabaceae, once they have been dried for storage the seeds of this species may benefit from scarification before sowing in order to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing[
