One of the most spectacular trees. Fast growing small to medium size tree with architectural crown structure and narrow pointed leaves that make this plant stand out from other cassias/sennas. Showy yellow flowers are scented and attract butterflies. The flowers come in big clusters and when the tree is in full bloom (Spring to Fall), the view is spectacular, hence the name. This plant looks very pretty as a container specimen or as a separately standing tree for a small yard. Prefers soils that are deep, moist and sandy but will tolerate calcareous soils. The rare plant doesn't exist in a wild anymore and can be found only in cultivation. The seeds of Cassia spectabilis are a potential source of commercial gum.
