Dendrobium tetragonum var. giganteum x tetragonum var. ‘alba’ is crossbred to produce unique flowers. This sympodial orchid has mainly green to gray, notable rectangular pseudobulbs. On the apical side of each pseudobulb, two to three lanceolate, thin leaves are produced. From in between the leaves, at the topside of the pseudobulbs, a short flower stalk could be formed that carries 2 to 6 scented flowers. The pendant flowers are around 1.5 cm long and have a base faint yellow color. The folded labellum shines with a bright white. This species flowers over longer periods of time; from autumn to spring new flower stalks could emerge. Older plants could reach a significant size over time and could grow out to a real specimen if cared for the right way. Propagation is easiest by dividing. Make sure every division has at least three pseudobulbs.

For this species, provide day temperatures between 16 and 25 degrees Celsius. At nighttime, a drop in temperature of around 5 degrees stimulates growth. Ideally, humidity is higher than 70% in its growing environment. When humidity is high, it is possible to grow this species mounted on bark or other media. Allow for optimal ventilation. The ideal potting media is an airy mix for epiphytes and could consist of medium sized bark. Place this plant in bright indirect light. Water this species regularly in the growing season which lasts normally from spring till summer. It is possible to let the medium dry out in between waterings in winter and store it in a cooler place. Fertilize this orchid weekly with a recommended dosage of specialized orchid fertilizer.
