The most important pioneer legume in the high-altitude Araucaria forest. Similar to acacia. Very fast growing, produces many flowers and seeds from the 3rd or 4th year onwards. Lives from 15 to 25 years. Good wood for firewood and “colored” flooring. Its seeds need heat to break dormancy. They remain in the soil for many years, waiting for a fire, the fall of a large tree or erosion for the sun to heat the earth and for it to germinate.
To plant, simply place the seeds in very hot water +- 80° and leave to soak for an hour or overnight. Drain well and mix with very dry ash or rock powder so it doesn't stick to your hands. Or mix in a wheelbarrow with sifted compost and sow with a spade. It is recommended to broadcast, in bare soil, in large quantities so that there is genetic selection of the best plants. Many people grow seedlings in bags, but the yield is much lower in the field. Very frost tolerant, except in the first months of life, so it can be planted right after heavy frosts until mid/late summer.
