Mericlones of an awarded plant, also known as the 'butterfly orchid'. Very large flowers that bloom on tall spikes. Successive bloomers, with each flower lasting about one month, with a 2 to 4 week wait between flowering on the same spike. Some plants have been known to flower 10+ years on the same spike! Great orchid!
Current plants are blooming size and can produce spikes within less than one year.
Intro:Psychopsis Mendenhall was first created through the hybridization efforts of Carter and Holmes Orchids and was registered in 1988. It is a hybrid between Psychopsis Butterfly (sanderae x papilio made by Ruben in Orchids, 1969) and Psychopsis papilio. The clone ‘Monarch’ was given an Award of Merit by the American Orchid Society. This particular clone is vigorous, with wide thick leaves that have a slight purple mottling on the edges and tips. The wide leaves give evidence that this clone may be a tetraploid. The butterfly-like flowers are large and can be 5 to 6 inches in size. The spikes are from 2 to 3 feet in height and can produce flowers for several years. This plant is easy to grow and flower if you follow the guidelines below.
Light:This plant requires light similar to Phalaenopsis but can be grown in somewhat shadier conditions. If your plant has large leaves and fails to bloom, moving it to more light will probably initiate flower spikes. East windows are ideal and this plant can be successfully cultivated under either fluorescent lights or high pressure sodium fixtures.
P.L. Lights systems are a great way to provide artificial light to your orchids. See our P.L. Lights page for more information on this great product we offer.Humidity:50% or higher is ideal. The use of humidity trays or room humidifiers is beneficial.
We offer two products that can help increase humidity levels. The humidity tray offered in black or white, and the Mist Maker. Water:It is best to use rainwater, distilled or reverse osmosis water. Municipal water with a pH of 7.5 or lower can also be used. Water this plant as the moss or bark mix just dries out. When in spike or flower water as the mix approaches dryness but do not allow the mix to become completely dry between watering.
Overwatering can cause several problems such as root rot and infectious bacteria/fungus in the potting medium. One product we offer that can help these problems if caught at an early stage is Phyton 27 bactericide and fungicide.Fertilizer:We highly recommend using Green Jungle Orchid Food, especially formulated to work with rain, distilled, reverse osmosis water or water low in alkalinity. Fertilize with Green Jungle every time you water if plants are planted in bark. Be sure to flush the mix with clear water only once per month to prevent fertilizer salt build up.
GrowMore 20-10-20 Ureafree for municipal or well water. Use at the rate of ½ teaspoon per gallon. If using GrowMore with rain, distilled, or reverse osmosis water, add back in 5 - 10% municipal or well water to supply the necessary calcium and magnesium. Fertilize every other watering in the summer and every third watering in the winter.
Another fertilizer offered is GrowMore 6-30-30 (Cymbidium and bloom boosting formula). Flowering:Flowering season can be almost any time of year. When the new growth is large enough, it will send out a spike from a small furrow in the pseudobulb just under a small leafy-like sheath. Flower spikes can reach 2-3 feet in height and are continuous blooming. The flowers come out singularly, one at a time, and stay open for about 2-3 weeks. They will fall, and very close to where that bud came out, another flower will appear. These spikes can bloom for many, many years, continually. Never cut the spike off unless it turns totally dead and crispy brown. If you accidentally break a spike, leave the remainder and it will branch and develop a new spike. It is not uncommon to have a spike produce flowers for 12 years or more.Repotting:These plants prefer a well drained mix with a lot of air. Clay pots are good for larger plants. Change the mix only as it breaks down; approximately every two years. The best time for repotting these plants is in the spring months or when new growth is beginning to appear, as this is when the new roots will break at the same time. Potting mixes can include New Zealand sphagnum moss (with clay pots) or a medium grade bark mix.
We offer several different types of potting medium. Here are direct links to what we believe to be some of the best potting mediums available for orchids: Orchids Limited bark mix, New Zealand sphagnum moss, coco husk, coco peat, sponge rock, charcoal, tree fern fiber and cork slabs for epiphytic plants.
