Cannellini bean is a white-seeded bush variety of common bean (Phaseolus vulgaris), valued for its large, creamy dried seeds and their central role in Italian cooking. As a legume, it fixes atmospheric nitrogen through root nodules, leaving soil enriched for following crops. Plants reach 18–24 inches, need no staking, and complete their lifecycle in 70–90 days from direct sow.
Sow only after soil reaches 60°F; cold, wet conditions cause seed rot and patchy stands. Inoculating seed with Rhizobium leguminosarum inoculant before sowing boosts nitrogen fixation, particularly in beds where beans have not grown recently. Preferred soil pH is 6.0–7.0. For dry bean harvest, leave pods on the plant until tan and rattling; if wet autumn weather threatens, pull whole plants and hang them in a ventilated, covered space to finish curing. Properly dried seeds store well for several years.
Cannellini beans are the standard white bean in minestrone, ribollita, and pasta e fagioli, prized for their thin skin and creamy texture when cooked. They are high in plant protein and soluble fiber. Bean pod preparations have a documented folk-medicine history for blood sugar management and urinary support, and phaseolamin — an alpha-amylase inhibitor in common bean — has been investigated for its effect on post-meal glycemic response.
