The vireyas are in bloom again and right now is the time to take in their deletable beauty in the Camellia House at Planting Fields Arboretum on Long Island. The Arboretum has a very under-appreciated bevy of vireya species and cultivars. A collection almost unknown to the wider world, it might seem. Perhaps that’s because the Arboretum’s vireyas are grown in the Camellia House where most people in the region don’t think to find rhododendrons. Planting Fields does have masses of rhododendrons planted around the grounds as well. They’ll be blooming a little later in the season, though.
Vireyas are a different story. They’re too frost shy for the open garden on Long Island so they’re kept inside cohabiting with the collections’s tender camellias. At Planting Fields, the vireyas deservedly have their own gallery, though. To find them, you just need to stop being distracted by the exuberance of camellia blossoms and look for the small sign on a nondescript door off to the side. The one that simply says “Vireya Collection”, without any great fanfare or other attention getting devises. But go ahead, go on in. And be amazed.
Vireyas are found in a broad swath that extends across Southeast Asia, mainly in Borneo, New Guinea, the Philippines, Sulawesi and Sumatra. Although these regions are tropical, they grow mostly in the cooler mountains and cloud forests where the milder, more-temperate climate is more to their liking. They grow as both epiphytes high in the trees or in shrubberies in the understory. Botanically, vireyas are usually grouped as a section within the Rhododendron sub-genus of Rhododendron or sometimes broken off into a sub-genus of their own. Altogether they number about three hundred. And new species, such as the recently re-assessd Rhododendron atrichum from Sarawak and Borneo and the newly described Rhododendron trancongii from Vietnam, are still being added as the amazing plant and animal diversity of the more inaccessible parts these regions continue to be explored and studied.
