The theme of the flower show is 'Sikkim, nature's own garden' while the 'cymbidium orchid' will be the theme flower during the flower show to be held near Gangtok.
Exotic varieties of nearly 4,500 species of flowers, native to Sikkim, will be showcased before the national and international audience.
