One of my favorites and a very unusual orchid, Stanhopea tigrina comes from Mexico, growing large pleated leaves and features incredible flowers with intricate, complex structures for pollination by insects. Usually in the summer, flower spikes emerge downward so growing is best in a basket with gaps. Flowers are very showy with a spicy fragrance but only fresh for a few days. They will often bloom more than once a year.
I use bright indirect light, hanging under an open tree and water twice a week or more. Fertilizing at 1/2 strength monthly or more often. A larger mature plant is more able to support flowering.
Here are photographs of that plant today (not booming). The cultivar Stan. Tigrinya var. nigroviolacea ‘Predator’ was awarded an AOS FCC in 1996. We acquired the plant Matthias Seelis of Shogun Orchids at the 2019 Hilo Orchid Show. The bloom photos were taken at Pacific Heights on Oahu (elevation approximately 750 feet) on July 11, 2021.
