Question: Formosan pleione
I bought some bulbs of the orchid in question, it flowers pointulmente and then the bulb dies. What can it depend on?
I also look for cultural information on Bletilla striata (also an orchid).
Certainly of your collaboration in this regard, I greet distinctly.
Pleione formosana: Question: Pleione formosana
Thank you for contacting us about your orchids inquiries through the Expert's column.
A large group of plants and hybrids whose origins are predominantly tropical belong to the Orchid family
The Pleione formosana originating from tropical Asia, caducous pseudobulbosa, can be cultivated in the sheltered points of rocky gardens in the hottest parts, the very white flowers or sepals and mauve-pink petals, paler lip, stained with brick red, ginger or yellow, fringed. This is a species that needs a period of vegetative rest, generally autumn; in this period the plants lose their leaves and in some dry all the epigeal portion. During the rest period the waterings must be reduced and the atmospheric humidity must be reduced to a minimum. With regard to your question, the bulb of your orchid may have gone into vegetative rest as it is characteristic of this species.
Regarding the Bletilla striata this is native to the Far East (China and Japan), with long and shiny leaves, the inflorescences are about 30 cm long with several flowers of bright magenta pink. These plants grow well in a soft soil on external windowsills, the rhizomes tolerate well low temperatures up to a few degrees below zero even if for not very long periods, in a place where they can receive a lot of light in the vegetative period. It is also in this case of deciduous plants, which lose their leaves in autumn and enter into vegetative rest until late spring, in winter it must be kept cool and dry.
