Acineta orchids are native to tropical America growing from southern Mexico to Peru. There are approximately 15 species of Acineta orchids which are mostly epiphytic but also lithophytic. The name Acineta comes from the Greek word akintos which means immobile which refers to the rigid immobile lip of the flower.
Acineta orchid foliage resembles the leaves of the Stanhopea and Lycaste orchids, and the flowers are similar to Peristeria. They have pendant racemes with many flowers. Some of the species are fragrant such as Acineta barkeri, beyrodtiana, chrysantha, erythroxantha, and superb.
Most Acineta orchids grow epiphytically in wet forests at altitudes between 2400 and 6000 feet. Grow in baskets in moist intermediate to cool temperatures. Use potting media that drains well, such as bark and sphagnum moss. Plants that get too warm will stress and drop leaves as well as form keikis at the top of the pseudobulbs. Acineta require low light levels equivalent to Phalaenopsis orchids. Humidity needs to be 50% or over for best results. Fertilize once a month. Let potting mix completely dry between watering. In growing season at moderate temperature water thoroughly once a week or so, depending on how dry it is and spray over head from day to day. Plant requires rest in winter time. Keep mostly dry during this time. Propagation is done by dividing the plants in early spring before the growing starts.
Acineta are prone to spider mites and scale. Always inspect new orchids for these pests before putting them with your existing plants to prevent spreading.
Acineta orchid flowers normally bloom from spring to early summer. 20 to 30 flowers is a common occurrence.
