Origins and History
The Thorogreen Lima Bean (Phaseolus lunatus) is a classic heirloom variety introduced in the mid-20th century and valued for its quick maturity compared to other lima beans. Thorogreen was selected from Henderson Bush and released in 1941. It descends from traditional lima cultivars grown in the southeastern United States, where the warm climate and long summers allowed for prolific harvests. Thorogreen was developed for its tender, flavorful beans and compact growth habit, making it suitable for both home gardens and market production. Its reputation as an “early” lima bean helped popularize it among gardeners seeking dependable yields in shorter growing seasons.
Appearance and Characteristics
Thorogreen plants are bush-type limas, reaching about 18 to 24 inches in height, with lush green foliage and sturdy stems. The pods are medium-sized, pale green, and typically hold 3 to 4 plump, light-green seeds. The beans maintain their color well when cooked and are prized for their buttery texture and mild, nutty flavor. This variety is self-supporting, requiring no trellising, and produces abundantly over several weeks.
Culinary Uses
Also called "Cangreen Bush", this is an old-time favorite with a concentrated harvest window making it perfect for canning, freezing, or making large batches of soup. Thorogreen Lima Beans are known for their tender texture and subtle sweetness, making them a versatile kitchen staple. They can be enjoyed fresh, steamed, or boiled, and are often used in succotash, stews, or casseroles. They also freeze well, retaining flavor and texture for off-season use. Their smooth, buttery quality pairs well with corn, tomatoes, smoked meats, and herbs like thyme or basil.
Growing Tips (Vegetation Zones and Sow Depth)
Thorogreen thrives in USDA Zones 6–9, preferring full sun and well-drained, fertile soil. As a warm-season crop, seeds should be sown directly outdoors once soil temperatures reach at least 65°F, typically 1 to 1½ inches deep and spaced 4 to 6 inches apart in rows 24 to 30 inches apart. Avoid planting in cold or wet soils to prevent rot. Consistent moisture during flowering and pod development is key for high yields, but waterlogging should be avoided.
Harvesting Guidance
Thorogreen Lima Beans mature in about 65 to 75 days, making them one of the fastest-producing lima varieties. Harvest when pods are plump and seeds inside are fully formed but still tender. Regular picking encourages continuous production. For fresh eating, shell and cook promptly; for storage, beans can be frozen after blanching or dried for longer keeping.
