Most of my favorite orchids are those that are unique in some way. I may not grow them but they still fascinate me.

So, how about the biggest orchid in the world, Grammatophyllum speciosum? Common names include “Giant Orchid” and “Queen of the Orchids”.

How big is it? It wouldn’t fit in my greenhouse. Over 10 feet wide, weighing over a ton, with pseudobulbs up to 10 feet tall and inflorescences an additional 10 feet long. The blooms are up to 4 inches wide.

Grammatophyllum speciosum grow in the rainforests of Southeast Asia and need lots of light and good air flow. They are usually epiphytic. Can you imagine something this big living in a tree?!!!

The inflorescence on its huge spikes can have over a hundred slightly fragrant blooms. The flowers themselves are usually yellow/green with maroon tiger-like markings which is why one of the common names is the “Tiger Orchid”. They only bloom once every few years, often after a stressor event like a drought followed by heavy rains.

In some Southeast Asian countries, Grammatophyllum speciosum is associated with prosperity, longevity, and prestige. It is often planted in royal gardens, temples, and public botanical displays. Obviously, full grown plants are rarely found in private gardens.

Interestingly, the lower flowers on the spike are “imperfect” male flowers which don’t have a lip. The upper flowers are “perfect” containing both male reproductive parts (stamens) and female reproductive parts (pistils). The male flowers are also more fragrant to attract pollinators.

Lucky for me, there are lots of orchids in the world that are unique and interesting with fascinating stories. I hope to see one of these on the raffle table soon! :-)
