This one is probably the most widely grown flower plant in India, and even though you may have somehow skipped hearing its name, you certainly are familiar with its ethereal, feather-light beauty. Yes, we are speaking of the Bougainvillea Glabra flower plant.
What is Bougainvillea Glabra?
Since French explorer Louis Antoine de Bougainvillea (the flower is named after him) introduced this plant to the world in the 18th century, Bougainvillea has come a long way. One of its varieties, Bougainvillea glabra is not a climber. Despite being a common sight all around, it is not recognised by its actual name. In India, this evergreen plant with thorny stems is highly popular. Due to its drought-resistance and hardy nature against hot and dry climates, it is one of the most common plants used to adorn boundaries and compound walls. Most popular in the country of its origin, Brazil, Bougainvillea glabra has found admirers across the globe.
Typically used to decorate yards and backyards, its flowers are edible and are often used to prepare teas, salads and various beverages despite their bitter taste. The Bougainvillea glabra climber is also used to control weeds.
Bougainvillea Glabra: Physical description
Bougainvillea glabra is a woody climber with extremely small (and typically white or off-white) flowers that have a highly attractive, colourful, paper-like texture that come in shades of pink, purple and red.
Commonly referred to as ‘paper flower’ or ‘lesser bougainvillea’, it should not be confused with ‘greater bougainvillea’, which has round floral tubes and longer floral bracts. Lesser bougainvillea or bougainvillea glabra has distinct, pentagonal floral tubes and short floral bracts.
With its drooping branches that are either glabrous or sparsely hairy, bougainvillea flaunts dark green, elliptical leaves, arranged spirally along the branches, being widest along the middle.
