Grammatophyllum scriptum the most common Grammatophyllum, it has a plethora of varieties and forms

The green form sometimes called var. Crinitum

A particularly nice flower of the most common form

An oddly shaped flower with more green than purple

A small flowered type sometimes called multiflorum, which may be a different species or just a small flowered form

A well grown plant of Gramm. scriptum

I have not been able to grow this species with the same success as the other species of the Grammatophyllum genus that I have.  I am starting to wonder whether this has to do with the particular plants of this species that I brought.  So I probably will be trying to grow this species again in the future.  When well cared for this species can grow into a specimen plant of hernia inducing, disk slipping proportions.  Basically it can grow into as large an specimen plant as you are willing to carry around.   There are so many varieties and forms of this species available in the market that you can go all the way from gargantuan plants with towering inflorescences to tiny few flowered plants with inflorescences barely one feet long.

In my experience scriptum produces some of the largest root baskets I have ever seen.  I have concluded that successful care of this species depends on mantaining these root baskets in good condition.  You can read about the culture of these plants under the heading of Gramm. elegans.
