Harvard University Herbaria and Botanical Museum: A Global Center for Plant Science
Located at 22 Divinity Avenue in Cambridge, Massachusetts, the Harvard University Herbaria (HUH) and the Botanical Museum represent some of the most significant botanical resources in the world. As integral components of the Harvard Museum of Natural History, these institutions serve as vital hubs for research, preservation, and the study of plant life across geological time.
The Harvard University Herbaria
Founded in 1842 by Asa Gray, the Herbaria have grown into one of the ten largest collections of its kind globally. With over 5 million specimens, the Herbaria, combined with the Botany Libraries, constitute the largest university-owned herbarium in existence. The Gray Herbarium, named in honor of its founder, remains a cornerstone of this collection.
By the time of Gray's retirement in the 1870s, HUH had established itself as the primary center for botanical research in the United States. Today, it continues to support global science by hosting the Gray Herbarium Index (GCI) and maintaining an extensive database of specimens, botanists, and publications. Furthermore, the materials held here serve as one of the three major sources for the International Plant Names Index (IPNI).

The Botanical Museum and its Evolution
The Botanical Museum was established in 1858, originally operating as the Museum of Vegetable Products. Its early mission focused on economic botany—the study of plants' practical uses—and horticulture. The museum's foundational materials were donated by Sir William Hooker, the director of the Royal Botanic Garden.
In 1888, Professor George Lincoln Goodale took over as director. Under his leadership, the museum's dedicated building was completed in 1890, providing essential research facilities and public exhibition spaces. This development acted as the botanical counterpart to the "Agassiz" Museum of Comparative Zoology. Subsequent directors expanded the museum's scope to include medicinal plants, archaeological materials, pollen, and artifacts.
Specialized Collections
The Botanical Museum houses several prestigious collections that span the history of life on Earth:
- Oakes Ames Collection of Economic Botany: Focused on the utility of plants.
- Paleobotanical Collection: Includes the Pollen Collection and features significant Precambrian material containing early life forms.
- Margaret Towle Collection of Archaeological Plant Remains: Provides insight into ancient plant use.
The Remarkable Glass Flowers
One of the most celebrated treasures within the university is the Ware Collection of Glass Models of Plants, widely known as the "Glass Flowers." Commissioned by Goodale and sponsored by Elizabeth C. Ware and her daughter Mary Lee Ware, these models were meticulously crafted by Leopold and Rudolf Blaschka between 1887 and 1936.
This collection is unique in the world, consisting of approximately 4,400 models. These include life-size and enlarged representations of parts from over 840 different species, offering an unparalleled level of botanical detail.
Institutional Connectivity and Resources
The Botanical Museum is physically connected to the Peabody Museum of Archaeology and Ethnology. Visitors can access all museums within the Harvard Museum of Natural History through a single admission. For scholars, the Botany Libraries are a vital resource and serve as a founding member of the Biodiversity Heritage Library.

Frequently Asked Questions
What is the significance of the Glass Flowers?
The Ware Collection of Glass Models of Plants is a unique collection of approximately 4,400 highly detailed glass models created by Leopold and Rudolf Blaschka. It is the only collection of its kind in the world.
Where are the Botany Libraries located?
The Botany Libraries are located within the Harvard University Herbaria building.
What is economic botany?
Economic botany is the study of how humans use plants for various purposes, such as food, medicine, and industry. This was a primary focus of the Botanical Museum during its early years.
How can I visit the museums?
The Botanical Museum is part of the Harvard Museum of Natural History. It is physically connected to the Peabody Museum of Archaeology and Ethnology, and one admission provides access to all these museums.
What kind of ancient plant life is studied there?
The museum's paleobotanical collections include Precambrian material, which contains some of the earliest known life forms.
