A species in the Paphiopedilum subg. Cochlopetalum, native to Indonesia and Malaysia, known for their spiral-shaped petals and successive blooms on the same inflorescence, lasting up to 3 years straight! The primulinum happens to be the longest re-flowering species amongst the subgenus. On average, the first growth can flower for about one year. Subsequent growths can have longer-lasting spikes as the plants get larger.
Grow moist, almost similar to Phragmipedium, as these plants thrive on moist root systems.
