Seven Thousand Butterflies Fill the Conservatory Every Spring

Every spring, Frederik Meijer Gardens releases thousands of tropical butterflies into its five-storey conservatory and the region queues up to stand among them. Fred and Dorothy Fichter Butterflies Are Blooming reached its thirty-first year in 2026, and the organisation describes it as the largest temporary tropical butterfly exhibition in the United States: around seven thousand butterflies from more than sixty species, flying free in a fifteen-thousand-square-foot glasshouse.

The exhibition runs through March and into April. Exact start and end dates are set each year, so confirm with Meijer Gardens before planning travel around it.

The practical advice is unusually specific here, because the crowding is unusually severe. Go at opening, on a weekday, outside the school holidays. By late morning on a March Saturday the queue reaches outside the building and the conservatory itself is shoulder to shoulder. The butterflies do not care. The people photographing them do.

Dress for the conservatory rather than for the car park. The glasshouse is kept warm and humid for the insects, which in a Michigan March means walking in wearing a winter coat and immediately wanting to take it off. Leave it in the car or expect to carry it.

A few things visitors routinely get wrong. Butterflies land where they like and you should not touch them or pick them up. Pushchairs are difficult in the busiest hours and the staff will steer you. And the rest of the site — the thirty-acre sculpture park, the eight-acre Japanese garden — is usually still bleak and muddy in March, so this is a conservatory visit rather than a full day out.

If you want the gardens rather than the butterflies, come in late April or May, when the exhibition has closed, the outdoor collection has come back to life and the crowds have gone entirely.

Admission is charged and prices are reviewed periodically, so check the current rate rather than budgeting from any secondary source.
