It’s like being hit with a ton of … blossoms.

“The Orchid Show: Singapore,” the New York Botanical Garden’s 17th annual orchid extravaganza, running through April 28, features the natural species and hybridized sensations of Southeast Asia — upward of 70 percent of the display in the Enid A. Haupt Conservatory. Thousands of them, in hundreds of varieties and every conceivable — and inconceivable — shape, size and color.

The orchid, once an aristocratic rarity, now a ubiquity — you can buy them at Home Depot — is still the most unnatural-looking flower of the natural world, dizzying in its opulent, adamant oddity. And that’s just one on its own.

“It’s actually surpassed the poinsettia as the most horticulturally produced crop in the world,” said Marc Hachadourian, senior curator of orchids at the New York Botanical Garden. “They’re the pandas of the plant world — they’re charismatic, they’re colorful, they’re engaging.”
