Pink Shower Tree Seeds

Pink Shower Tree (Cassia grandis) is one of the most spectacular flowering trees found in tropical and subtropical climates. Each spring, before the new foliage fully emerges, the tree becomes covered with long, pendulous clusters of soft pink flowers that create a breathtaking display. The abundant blossoms gradually deepen in color as they mature, making this tree a stunning focal point in any landscape. Its broad canopy also provides excellent shade, while the flowers attract bees, butterflies, and other beneficial pollinators.

Native to Central America and parts of South America, Pink Shower Tree is prized for its rapid growth, graceful branching, and exceptional ornamental value. It is an outstanding choice for parks, botanical gardens, large residential landscapes, and tropical streetscapes.

Seed Germination

Pink Shower Tree seeds have a hard seed coat that should be scarified before planting to improve germination. Lightly nick or sand the seed coat, then sow approximately ½ inch deep in a well-draining seed-starting mix. Keep the growing medium consistently warm and lightly moist. Using a humidity dome helps maintain ideal moisture levels until seedlings emerge.
