Mast Arboretum: Where Texas’ First University Garden Blossoms with 7,500 Species

The Mast Arboretum is a renowned 10-acre botanical and educational garden located on the campus of Stephen F. Austin State University (SFA) in Nacogdoches, Texas. Nestled along the scenic LaNana Creek, it stands as one of the most significant horticultural resources in the state. Established in 1985 as a class project by SFA’s first landscape plant materials course, the arboretum has since evolved into a living laboratory supporting education, research, and conservation. It serves as a vital part of SFA Gardens, which together encompass over 138 acres of themed landscapes across the university.

History and Purpose

The Mast Arboretum began as a hands-on learning space for horticulture students and quickly grew into a center for plant evaluation and education in East Texas. Named in honor of Dr. David and Janet Mast, early supporters of SFA’s horticulture program, the arboretum was developed to test the adaptability of plant species to the climate of the southern United States. It remains a key training ground for students studying botany, environmental science, and landscape horticulture, offering opportunities to engage in plant research, garden design, and ecological restoration.

Plant Diversity and Collections

Today, the Mast Arboretum features more than 7,500 species of plants from around the world, making it one of the most botanically diverse university arboreta in the region. Its collections include a wide range of trees, shrubs, vines, perennials, and ornamental plants suited to the southern U.S. climate. The arboretum serves as an important testing site for evaluating new cultivars and rare species, contributing to horticultural research and conservation.

Themed Gardens and Features

The arboretum is known for its thoughtfully designed themed gardens that highlight the diversity and adaptability of plant life. These include the Asian Valley, Conifer Collection, Holly Row, Fern Gully, Dry Garden, and a bog garden featuring pitcher plants and other native wetland species. Visitors can also find herb and butterfly gardens, as well as seasonal plantings that reflect the unique flora of East Texas. Each garden provides an immersive educational experience, allowing guests to explore both native and exotic species in carefully curated landscapes.

Educational and Community Role

As the oldest university-based arboretum in Texas, the Mast Arboretum plays a central role in the state’s horticultural education. It supports teaching and research at SFA, hosting workshops, field classes, and plant trials. The arboretum is also deeply integrated into community life through its association with SFA Gardens, which organizes seasonal plant sales, conservation events, and outreach programs that engage students, families, and local gardeners. These efforts foster environmental awareness and promote sustainable landscaping practices throughout East Texas.

Legacy and Significance

Over four decades since its founding, the Mast Arboretum continues to exemplify the integration of education, research, and public service. Its extensive plant diversity and accessible layout make it a valuable resource for students, botanists, and visitors alike. More than just a collection of plants, it reflects a living commitment to environmental stewardship, serving as both a scientific and cultural landmark in the Garden Capital of Texas.
