Grammatophyllum scriptum – Back Bulb Division

Grammatophyllum scriptum is one of the most impressive of all orchid species, renowned for its large size, bold markings, and spectacular flower spikes. Native to the Philippines and surrounding Pacific islands, it produces tall, arching racemes of greenish-yellow blooms heavily spotted in deep brown. Mature plants can carry dozens of long-lasting flowers at once.
