In Sarawak we saw Grammatophyllum speciosum growing in Mulu National Park and this related species is also found in Sarawak.
Grammatophyllum scriptum is a large growing species with a wide natural range including Borneo, the Lesser Sunda Islands, the Moluccas, The Philippines, Sulawesi, the Solomon Islands, the Bismark Archipelago, Papua and New Guinea, Fiji and Santa Cruz Islands. The species is restricted to areas near the coast up to 100m and so enjoys a hot climate and bright light.
We do our best to replicate the natural habitat by growing plants high in Warm Asia (Min 17C) but the species would enjoy higher temperatures and we keep plants drying in the winter to avoid damage on cooler nights.
The flower spike this year is well over 1m long with around 150 flowers each 4cm across and it makes a terrific sight.
