The Mayo Bilobal Gourd is a distinctive ornamental and utilitarian variety of bottle gourd collected from the Mayo River Valley in southern Sonora, Mexico, where it has been cultivated for generations. Named for its characteristic two-chambered shape, with a smaller upper chamber and larger lower body, this frost-tender annual thrives in hardiness zones 9 through 11 and grows best with moderate watering and well-draining soil between pH 6.0 and 7.0. Traditionally fashioned into canteens and water vessels by stringing with agave fiber, it remains prized by craftspeople today for shaping into decorative birdhouses and functional home goods.

This gourd carries the practical heritage of the Mayo people, transformed from daily necessity into modern craft. The distinctive bilobal shape, with its pronounced upper chamber, makes it instantly recognizable and unusually versatile, working equally well as a utilitarian container or an artistic sculptural form. Seed savers and heritage gardeners value it for its living connection to Sonoran agricultural tradition, while crafters appreciate how naturally the two-chambered body lends itself to functional and decorative work.
This gourd is grown primarily for crafting and decoration rather than food. Once mature and fully dried, the hollow shells serve as functional canteens, water vessels, and storage containers. Contemporary gardeners and artisans carve, paint, and shape them into birdhouses, decorative wall hangings, and functional home goods. The distinctive bilobal form makes it particularly suited to pieces where the natural two-chambered shape can be incorporated into the design.

Start seeds indoors 3 to 4 weeks before your last spring frost date in soil kept between 70 and 85 degrees Fahrenheit. Sow seeds at a depth of 1 inch in seed-starting mix and keep consistently moist until germination, which typically occurs within 7 to 10 days. Transplant seedlings under grow lights in a warm location until they develop their first true leaves.
Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days once soil temperatures reach at least 65 degrees Fahrenheit and all frost danger has passed. Transplant into garden soil spaced 3 to 4 feet apart in rows 6 to 8 feet apart, or space individual plants 6 feet apart if trellising vertically. Plant seedlings at the same depth they were growing in their containers and water thoroughly after planting.
Direct sow seeds outdoors in late spring after soil has warmed to at least 65 degrees Fahrenheit and all frost danger has passed. Plant seeds 1 inch deep, spacing them 6 inches apart initially, then thin seedlings to final spacing of 3 to 4 feet apart.
Allow gourds to mature fully on the vine until the stem begins to dry and turn brown, indicating the gourd is ready for harvest. The skin will harden and change to a tan or cream color as it matures. Cut gourds from the vine with several inches of stem attached and cure them in a warm, dry, well-ventilated space for 2 to 3 weeks until the skin is completely hard and the interior has dried thoroughly. Once fully cured, the gourd is ready for carving, crafting, or use as a functional vessel.

“The Mayo Bilobal Gourd originates in the Mayo River Valley of southern Sonora, Mexico, where the Mayo people developed and refined this cultivar over centuries. Traditionally hollowed and dried to serve as canteens for carrying water, the gourds were often strung with ixtle, a strong fiber harvested from agave plants, creating a portable vessel suited to the region's arid climate. This variety was preserved and eventually collected by Native Seeds/SEARCH, the Arizona-based seed organization dedicated to safeguarding heirloom crops of the southwestern United States and Mexico, where it now resides in their Seed Bank Collection as a living link to Mayo agricultural knowledge.”
