Phragmipedium kovachii
Phragmipedium kovachii, discovered in 2001, is the most remarkable new orchid of the last 100 years. The flowers of wild-type plants are 4-6 inches (11-15cm) across, by far the largest flowers in the Phragmipedium genus. The flowers are a bright pink color, and have very good shape, with wide petals and dorsal sepals. Orchid breeders are just getting started on these plants; within a few generations they will most likely have significantly improved the flower size and quality, and hybridization programs will be better-established (though early efforts have been exciting!)
In their native cloud-forest habitats, it rains almost every day and humidity is high, about 70% most of the time. Water them daily or even set them in a dish filled with water. Fertilize regularly at low concentrations.
They are most comfortable at cool-to-intermediate temperatures, 65-75°F (18-25C) during the day with a 10-15°F drop at night (6-8C).
They like a potting mix that is neutral to slightly alkaline. Fine fir bark with a small amount of crushed seashells is appropriate. I've also read that diatomaceous earth works well, with a similar particle size.
Provide intermediate light, about 2000 footcandles. More than Phalaenopsis lighting but less than Cattleya lighting. In other words, bright but filtered sunlight, such as a bright east window or a slightly-shaded south window in the northern hemisphere.
