About Lima bean
Phaseolus lunatus, commonly known as Sieva bean or Lima bean, is an annual climbing legume prized for its edible seeds. Its flat, curved pods contain white to greenish beans, and its flowers are typically white or pale purple. It's an excellent choice for home gardens and as a cover crop to improve soil fertility.
Native range
Central and South America
Care tips
It requires full sun (at least 6-8 hours daily) for good pod production. The soil should be well-draining, slightly acidic to neutral (pH 6.0-7.0), and rich in organic matter. Keep the soil consistently moist, especially during flowering and pod development, but avoid waterlogging. A common mistake is planting too early in cold soils, which can inhibit germination and growth.
