Dendrobium nobile is the collective name for spring-flowering species in the genus Dendrobium.
Dendrobium nobile is a deciduous species in the genus Dendrobium. The inflorescence is produced on the upper stem nodes of the pseudobulbs of the previous year, with 2 to 3 flowers in a bunch. After flowering, new buds grow from the base of the pseudobulbs and develop into new pseudobulbs in the same year, while the old stems gradually crumple and generally do not flower again. Sometimes the dormant teeth on the old stems will sprout and grow into small plants with roots, and these old pseudobulbs and small plants are usually used as propagation material. After the weather turns cooler in autumn, the plants gradually go into dormancy and form flower buds at cooler temperatures.
Dendrobium nobile likes warm and moist environment, the suitable temperature for growth and flowering is 10-30℃, it can tolerate low temperature of 2-3℃ in winter and high temperature of over 30℃ in summer, but too high or too low temperature will inhibit the growth of the plant and some leaves will be damaged. In sufficient and soft sunlight grows well, if the light is not enough then the plant grows, the leaves are thin and tender, the leaf color turns thick green, the growth is slowed down, prone to pests and diseases, while in the light is sufficient, the plant grows luxuriantly, the leaves are broad and glossy, the flowers are colorful and the flowering period is extended. Also avoid strong light exposure, 50% of the sunlight should be shaded off in summer, and full light should be given in other seasons, and it is advisable to keep low light exposure when flowering, which is beneficial to the quality of the flowers.
