The tiny flowers are often strung together into strands, sometimes along with white jasmine flowers and therefore in great demand for making garlands which are offered to temple deities or used to embellish women's hair.
Name
The common name "firecracker flower" refers to the seed pods, which are found after the flower has dried up, and tend to "explode" when near high humidity or rainfall.
The "explosion" releases the seeds onto the ground, thereby creating new seedlings. The Latin specific epithet ''infundibuliformis'' means funnel or trumpet shaped.
