Gov. Gen. Frank Murphy declared Sampaguita as National Flower of the Philippines through Proclamation No. 652 s. 1934 as it symbolizes purity, simplicity, humility, devotion, dedication, fidelity and strength.
The sweet-scented Sampaguita (Jasminum sambac) is a species of jasmine native to southwestern, southern, and southeastern Asia. Sampaguita is a Spanish term, which comes from the Filipino words sumpa kita meaning ''I promise you''.
It is an evergreen vine or shrub reaching up to 1-3 m tall. The leaves are ovate, 4-12.5 cm long and 2-7.5 cm broad. The flowers bloom all throughout the year and are produced in clusters of 3-12 together. They are strongly scented, with a white corolla 2-3 cm diameter with 5-9 lobes. The flowers open at night, and close in the morning. Sampaguitas do not bear seeds and the plant is cultivated solely by cuttings. It is widely grown as ornamental plant throughout the tropics.
