The bombaco is an evergreen plant native to the rainforests of Central America and Brazil, which in nature can reach 18 meters in height, also called Malabar or Guyana walnut. It has large leaves of light green, shiny, palmate, and very fragrant flowers, large up to 15 cm in diameter, creamy-white in color, with the petals curled towards the base of the flower, to show the stamens. At the end of the summer the flowers are succeeded by fruits, woody capsules which, when ripe, break into five longitudinal segments, allowing the seeds of edible nuts to escape. In nature, the plant often develops multiple trunks, this feature makes the pachira very decorative, in fact, it is often found on the market exemplars with multiple intertwined trunks, ideal for transforming the home garden into an exclusive and beautiful living space.
The pachira insignis likes very bright positions, but not the direct rays of the sun, which could burn the leaves; in the summer it is advisable to place it outside, possibly in partial shade, when it is cold, put it in the house, otherwise it could lose its leaves. If kept in too shaded place the pachira insignis develops a foliage of reduced dimensions.
To guarantee the right pachira insignis moisture content, it is good to remember its origins, the rain forests; the soil must therefore be kept humid, but without soaking it to avoid water stagnation and radical rot. It is therefore advisable to water it often, but not excessively, waiting for the soil to dry a little between one watering and another. It is advisable to dissolve the fertilizer for green plants every 15-20 days in the water of the watering to guarantee an optimal growth to the plant.
The soil is the main source of plant sustenance and for this reason, when a new species is cultivated, it is advisable to inquire about the specific needs of the plant. The universal balanced soil is an excellent compound for this kind of plant, remembering that it is very important that the soil is well drained; if we fear water stagnation, remember to place a layer of coarse-grained material, such as pumice stone or clay granules, at the bottom of the vase, to allow a better flow of excess water.
For the reproduction of our bombaco seeds are used, which must be planted as soon as the capsule that contains them opens in a mixture of sand and peat in equal parts, germination is usually rapid, occurs in less than a month, but the seedlings go transplanted into individual pots only when they have produced at least two leaves. It can also be done by cutting, to be practiced in spring; they must be rooted in a mixture of peat and sand in equal parts.
