Sesbania grandiflora: complete guide

Overview

Sesbania grandiflora, commonly known as vegetable hummingbird tree, August flower or Agati, is a beautiful tropical tree from the Fabaceae family. This tree grows naturally in Malesia to New Guinea and the Philippines. In warm climates, this tree is valued for its large, spectacular flowers and fast growth.

The tree is known for its enormous red or white flowers that are larger than normal flower clusters. This tree is edible and provides food and nutrition in tropical countries.

Appearance and Bloom

Sesbania grandiflora is a fast-growing tree that can reach four to ten meters tall under ideal conditions. Growth is very rapid, especially in warm, humid climates.

The leaves are compound (pinnate), approximately thirty to fifty centimeters long with twenty to forty pairs of small leaflets. The leaves are bright green and fine in texture. The tree forms a light, open crown.

The flowers are the most striking feature. They appear throughout much of the year in tropical climates. The flowers are large, approximately four to six centimeters long, and larger than flower clusters. They are bright red or white (depending on cultivar), with thin petals and long, prominent stamens.

The fruits are long, thin siliques (seed pods), approximately fifteen to thirty centimeters long. These contain a large number of small seeds.

Ideal Location

Sesbania grandiflora requires plenty of sun and tropical warmth. Plant this tree in a sunny spot where it receives at least six hours of direct sunlight per day.

Temperature is critical. The tree grows only in tropical climates, with temperatures permanently above fifteen degrees Celsius. In colder climates it does not grow.

The tree prefers protected locations. Heavy wind can damage branches due to the open crown structure.

The climate must be humid. This is a tree for the tropics, not for dry zones.

Soil

Sesbania grandiflora prefers well-draining, fertile, neutral soil. Prepare soil as follows:

• Forty percent garden soil
• Forty percent compost
• Twenty percent sand

The tree accepts pH between 5.5 and 7.

Good drainage is important. This tree cannot grow in waterlogged soil. Wet soil causes root rot.

Watering

Sesbania grandiflora needs regular water, especially during growth.

Growing period: Keep soil consistently moist. In tropical climate this means regular watering. Water once to twice per week, depending on rainfall.

The tree is sensitive to drought. Too much drought reduces flowering and growth.

Ensure good drainage. Wet feet lead to disease.

Pruning

Sesbania grandiflora needs minimal pruning. Prune in early season (before growth) to shape.

Remove only dead or damaged branches. Thinning some branches helps maintain the open crown.

The tree grows fast, so regular growth monitoring is needed.

Maintenance Calendar

All year: Regular watering. Growing period: Feeding monthly. Flowering peak: Give more water. Dry periods: Give extra water.

Winter Hardiness

Sesbania grandiflora is absolutely not winter hardy outside the tropics. The tree dies at temperatures below fifteen degrees Celsius. Temperatures below ten degrees Celsius cause plant death.

This tree is only suitable for permanently warm climates such as South America, Africa and Asia.

Companion Plants

In tropical gardens, Sesbania grandiflora grows well with:

• Mango: Other tropical fruits
• Jackfruit: Other tropical trees
• Neem: Medicinal trees
• Papaya: Fruit trees
• Banana: Herbaceous trees

These combinations create tropical fruit garden combinations.
