Cassia grandis plant seedlings

Cassia grandis

Common name: Pink Shower Tree. Family: Legumes (Fabaceae)

the introduction

The Cassia grandis tree is a tropical flowering tree native to parts of Central and South America and the Caribbean. It is characterized by its wide crown, compound pinnate leaves, and pink, salmon-pink, or light orange flowers that grow in clusters hanging from the branches. It produces long, dark, cylindrical pods containing numerous seeds. Cultivated for ornamental purposes and shade, it attracts attention during the flowering season with its distinctive flower colors.

☀️ Lighting (Light)

It prefers direct sunlight and grows best in open locations that receive sunlight for most of the day. Ample light promotes growth and flowering, while heavy shade can reduce the number of blooms and weaken growth. It thrives in warm climates but may be damaged by cold and frost.

💧 Irrigation (Watering)

Young seedlings need regular watering during their establishment phase, maintaining moderate soil moisture without waterlogging. Once established, the tree can tolerate short periods of drought, but it grows best with adequate moisture throughout the growing season. Deep watering is recommended when the top layer of soil is dry, taking care to avoid waterlogging around the roots.

🌱 Soil & Growing Medium

It prefers relatively fertile soil rich in organic matter, with good drainage. It can grow in loamy and sandy soils improved with organic matter, provided the roots have adequate aeration. When planting in pots during its early stages, it is advisable to use a fertile and well-draining potting mix, keeping in mind that the tree is large and not suitable for permanent planting in small pots.

🌿 Fertilizing

A balanced fertilizer can be used during the growing season, especially in spring and summer, to support leaf, shoot, and flower growth. Moderate application is recommended, depending on soil fertility and plant condition. Over-fertilization, particularly with nitrogen-rich fertilizers, should be avoided as these may encourage vegetative growth at the expense of flowering.

🌳 Growth Habit

A medium to large tropical tree, typically reaching 10–20 meters in height under favorable conditions. It has a broad, rounded crown, spreading branches, and pinnate compound leaves composed of numerous oval leaflets. It bears clusters of pink or salmon-colored flowers, which may appear on the branches before or simultaneously with the leaves. It produces long, dark, relatively hard, cylindrical pods containing numerous seeds and an inner pulp. It requires ample space for crown and root development and is well-suited to large gardens and warm, frost-free areas.

⚠️ Toxicity & Safety

It is not advisable to consume the seeds or any other plant parts without first ensuring their safety, as their properties may vary depending on the part of the plant and the method of preparation. Pods and seeds should also be kept away from children and pets, and plant parts should not be used for food or medicinal purposes without a reliable source of information.
