Ascocentrum ampullaceum ‘Alba’ is a beautiful, rare miniature orchid that excels with its sparkling white flowers and compact growth habit. This particular variety is a real eye-catcher for any orchid novice or collector looking for something sophisticated and unique.
Ascocentrum ampullaceum is native to the mountainous regions of India, Bhutan, Nepal, Myanmar and Thailand. In its natural habitat, this species grows epiphytically, high in the trees, where it enjoys plenty of light and constant air circulation. The ‘Alba’ form is an extremely rare, natural variety where the usual bright pink color is absent and has given way to pure white flowers.
This miniature orchid forms a compact rosette of sturdy, leathery leaves. During flowering, it develops a richly filled blooming spike with numerous small, white flowers that give a delicate and pure appearance. The flowers are lightly scented and, under the right conditions, remain on the plant for several weeks. Thanks to its compact size, this orchid is ideal for smaller spaces, display cases or terrariums.
Ascocentrum ampullaceum ‘Alba’ desires bright, filtered light. Direct midday sun should be avoided, but morning or late afternoon sun is well tolerated.
This species feels at home in warmer conditions, with daytime temperatures between 22 and 30 C and nighttime temperatures around 18 C.
An aerated substrate such as fine bark or suspension on a mount (e.g., cork or tree fern board) is recommended. Good ventilation around the roots is essential.
A high humidity of about 60-80% is ideal. Regular misting is recommended if the environment is dry. This species also does well in a greenhouse.
During the growing season (spring and summer) fertilize weekly with a dilute orchid fertilizer (1/4 of the recommended dose). In fall and winter, reduce fertilization to once a month.
Use demineralized water or clean rainwater at room temperature. Keep the substrate slightly moist during the growing season, but allow it to dry out slightly between waterings. In winter, the plant may be slightly drier.
Flowering usually occurs in the spring. A shorter, cooler dormant period in winter may encourage flowering. If the plant feels well, it may bloom profusely each year.
