This moderate-sized tree typically grows up to 10 to 15 meters in height, but it can reach heights up to 20 meters. It has an open, spreading canopy with a rounded crown. The trunk is usually straight and sturdy, with a grayish-brown bark that becomes rough and furrowed with age. The leaves of Amaltas are alternate, pinnately compound, and deciduous. Each leaf comprises 7 to 15 pairs of leaflets, which are ovate and oblong.

The most striking feature of Amaltas is its abundant, showy flowers. The colorful golden-yellow flowers appear in long, drooping clusters called racemes. Each flower has five petals and measures about 4 to 5 centimeters in diameter. The blooming period generally occurs during the late spring or early summer.

Amaltas produce long, cylindrical pods that hang down from the branches following pollination. The pods are initially green and turn dark brown as they mature. They are woody and measure around 30 to 60 centimeters in length. Inside the pods, there are numerous Amaltas seeds embedded in a sticky, dark brown pulp.

To grow Amaltas from seeds, you can follow these steps:

  • Collect mature seeds from a healthy Amaltas tree. Look for brown or dark-colored pods that have dried and turned brittle. Ensure the pods are fully matured and have naturally split open to reveal the seeds inside.
  • Extract the seeds from the dried pods. Remove any remaining pulp or debris by rinsing the seeds with clean water. It’s important to note that Amaltas seeds have a hard outer coat that can inhibit germination.
  • Prepare a well-draining germination medium. You can use a mixture of equal parts compost, peat moss, sand, or vermiculite. Fill small pots or seed trays with this medium, leaving some space at the top for watering.
  • Place the scarified Amaltas seeds on the germination medium. Plant them about 1 to 2 centimeters deep, ensuring they are covered with the germination medium. Space the seeds a few centimeters apart to allow room for seedling growth.
  • Place the pots or trays in a warm and bright location, preferably in a greenhouse or a warm indoor area. Amaltas seeds require warm temperatures to germinate successfully.
  • Amaltas seeds typically take several weeks to a few months to germinate. Be patient and monitor the pots regularly. Once the seedlings emerge, they will initially have one or two small leaves.
  • When the seedlings have developed a few sets of true leaves and are large enough to handle, they can be transplanted into individual pots or containers filled with well-draining potting soil. Choose pots that allow for root development. Handle the seedlings carefully to avoid damaging the fragile roots.
  • Once the seedlings have grown stronger and reached a height of around 30 centimeters or more, they can be transplanted to their permanent outdoor location.

Amaltas generally grow well without the need for frequent fertilization. However, you can apply a balanced slow-release fertilizer in early spring to promote healthy growth and flowering. Use a fertilizer with an NPK ratio of 10-10-10 or 14-14-14. Follow the package instructions for application rates based on the size and age of the tree.


Pruning of Amaltas is usually minimal. However, you can prune the tree to remove dead, damaged, or crossing branches. Pruning is typically done during the dormant season, preferably in late winter or early spring, before new growth begins.

Pests and Diseases

Amaltas is relatively resistant to pests and diseases. Common pests that may affect Amaltas include aphids, caterpillars, and mealybugs. Regularly inspect the tree for any signs of pest infestation, such as curled or distorted leaves, sticky residue, or visible insects. Appropriate pest control measures, such as insecticidal soaps or horticultural oils, can be applied in case of infestation.

The tree is generally not prone to significant disease problems. However, it can occasionally be affected by fungal diseases like powdery mildew or leaf spots. Providing good air circulation, avoiding overwatering, and maintaining proper hygiene around the tree can help prevent these diseases.
