Pleione, Calanthe, Bletilla ir kt. rūšys bei hibridai
Formosana turi daug variacijų todėl ir toks žiedų skirtumas. Pas Ramsį (ir pas Neonodeta) netipinė forma, jau nepamenu pavadinimo, o pas Slogaa tipiška rūšis - rožinis žiedas su šviesia taškuota lūpa.

MOST IMPORTANT SPECIFIC CULTIVATION INSTRUCTIONS FOR PLEIONE
Temperature ; Most species and hybrids are frost resistant and withstand temperatures between minus 5 and plus 28 °C Except from a few autumn flowering species they do need a cold winter rest at temp’s between -5 ° C and +10 °C for two to three months to get good results . Many species do well when they get some frost in winter, if kept dry. It helps keeping pests under controle. They do not stand heat in summer , supply enough moisture at warm temp’s and if greenhouses get too warm , put them in a cool shady place outdoors .
Light ; One may give them full sunlight between November and February , and relatively cool shady conditions in growing stage, morning sun is beneficial though.
Humidity ; Critical is keeping plants dry in cold rest periods. As those plants are affected by monsoon rains in nature , they need abundant watering in peak summer . Watering need to be increased gradually as new growths start to develop . During growing season plants may not become dry, as the thin unbranched roots may be lost and will not be replaced afterwards ! We advise not to water on top as long as flowers have not gone over. Sensitive species could be watered from below until new leaf is fully developed.
Compost ; Very tolerant , most species do well with a compost of medium graded bark , pumice gravel and/or perlite and freshly fallen and cut oak and beech- leaves, more or less equal parts . Providing good drainage , one can use some moss or sphagnum to make it more water retentive. A cover of some kind of living moss has proved very beneficial for sensitive species . Several species are very salt sensitive, P. forrestii, P. grandiflora..., and require compost of bark/ sphagnum and quartz only, and plastic containers, no terracotta- .
Repotting ; Yearly, or each two to 3 years , in winter or in February latest , just before growing starts .
Water quality ; Rainwater is advisable , at least for salt sensitive species. Otherwise good quality tap water low salt and chlorine poor .Good oxygen rich water is essential .
Fertiliser ; Not before new roots are well developed, somewhere in July for most species. For hybrids and fast growing species one may use slow release grains up to 10 grains for strong growing hybrids or a good quality chemical fertiliser dissolved in spraying water. Salt sensitive species need very few high quality mineral fertilizer, late in the growing season only, preferable rich of potassium. And as most terrestrial orchids, the preferable N- source is Nitrate, no ureum and few ammonia .
Protection ; These are very strong plants, mites, aphides, snails and slugs can cause some trouble at the start of the growing and need to be controled to avoid spreading virus infection . It is more a question of getting growing conditions well balanced , especially the relationship temperature and humidity . For many species, exposure to frost in winter helps keeping pests under controle.
Galima ištraukti ar palikti keliems sezonams, aš visada ištraukiu ir padedu žiemoti vėsiai gumbelius. Visos dar šiltnamyje stovi, bet jau gal savaitgalį bandysiu parsinešti namo.
Mano atveju ne, jau turėjom ir šalnų ir vėsių naktų. Visos jau geltonais lapais arba gumbeliai jau be lapų.
Pas mane žydi pavasarį, kartu su krokais
