THE CONSERVATORY BALL

The Conservatory Ball is the New York Botanical Garden’s black-tie ball: a Thursday evening in late May or early June in the Bronx, with cocktails among the flowers of the Garden’s summer exhibition, then dinner and dancing in a tent, and the Enid A. Haupt Conservatory lit for the night. What it raises goes to the Garden’s research, teaching and gardens.

The first was held inside the glasshouse, to raise money to mend it. Five years earlier, it had been expected to come down.

The Glasshouse

The Garden was founded by an act of the New York legislature in 1891, three years after two botanists, Nathaniel Lord Britton and his wife, Elizabeth, had visited Kew. Cornelius Vanderbilt II, Andrew Carnegie and J. P. Morgan were among its first officers.

Its glasshouse was commissioned from Lord & Burnham, the leading glasshouse makers of the day, and drawn by William R. Cobb after the Palm House at Kew and Paxton’s Crystal Palace. Ground was broken on 3 January 1899, and it was finished in 1902, for a hundred and seventy-seven thousand dollars.

It is eleven pavilions of glass on steel and iron, in the shape of a C, five hundred and twelve feet long, rising at the centre to the Palm Dome, ninety feet high.

Renovations in 1935 and 1950 stripped away much of its ornament. It fell into decay and was vandalised, and by 1970 its demolition seemed inevitable.

Work to restore it began in February 1975, and that spring the first Conservatory Ball was held inside it, for four hundred and fifty guests, in the hope of raising twenty-five thousand dollars towards the work.

The city’s fiscal crisis put the work in doubt, and Enid Annenberg Haupt, who had published Seventeen, paid to carry it through. When the glasshouse reopened in March 1978, under her name, the cost had risen to five million dollars, and she had paid all of it. In 1981 she gave five million more to keep it.

It was restored again in the 1990s, over four years, and the Palm Dome once more in 2019 and 2020.

The Ball

The Ball celebrates the Garden’s summer exhibition, and is dressed to match it. For its fiftieth anniversary, in 2025, the exhibition was Van Gogh’s Flowers.

Guests take cocktails at seven among the exhibition, and sit down at eight, some five hundred of them, in a tent hung with flowers. The dancing follows dinner.

Each year’s Ball has its chairs, and its journal salutes those who give.

In 2026 it was held on 4 June and celebrated Flower Power, an exhibition of flowers as symbols of peace and love in the 1960s.

What to Know

It is held on a Thursday evening in late May or early June: cocktails at seven, dinner and dancing at eight.

Black tie.

Tables and single tickets are sold by the Garden.

Metro-North runs from Grand Central to Botanical Garden station, across the road from the Garden’s gate, in twenty minutes. Stay in Manhattan.

The mistake is to spend the cocktail hour at the bar. It is the hour to walk the exhibition, while the Garden is closed to everyone else.

The Court

The Conservatory Ball is not the Court’s own. Places at the Ball are sought on a member’s behalf, and the Court arranges the whole of it: getting there, where to stay in Manhattan, and the table afterward. The Court’s own morning among the glasshouses, The Conservatory, is in December.

How one becomes a member is set out under Admission.
