Dendrobium nobile
Dendrobium nobile is a general term for spring flowering varieties in the Dendrobium genus.
Dendrobium nobile is a deciduous variety of Dendrobium officinale, which produces inflorescences on the upper stem nodes of the pseudobulbs in the previous year, with 2-3 flowers per bundle. After flowering, new buds grow from the base of the false bulb, which develops into new false bulbs in the same year. The old stem gradually shrinks and generally no longer blooms. Sometimes dormant teeth on the old stem will sprout and grow into small plants with roots, which are usually used as reproductive materials. After the autumn weather cools down, plants gradually enter a dormant period and form flower buds at low temperatures.
Dendrobium nobile prefers warm and humid environments, with a suitable temperature for growth and flowering of 10-30 ℃. It can tolerate low temperatures of 2-3 ℃ in winter and temperatures above 30 ℃ in summer. However, high or low temperatures can inhibit plant growth and damage some leaves. It grows well under sufficient and gentle sunlight. If there is insufficient sunlight, the plant will grow excessively, with thin and delicate leaves that turn to dark green, slowing down growth and making it prone to pests and diseases. However, in areas with sufficient sunlight, the plant will grow vigorously, with wide, thick, and glossy leaves, bright and colorful flowers, and an extended flowering period. At the same time, avoid strong light exposure, block 50% of the sunlight in summer, and provide full light in other seasons. It is advisable to maintain weak light exposure during flowering, which is beneficial for the quality of the flowers.
