The Marmande tomato is a popular, large French heirloom variety known for its rich, savory flavor, meaty texture, and few seeds, making it great for slicing in sandwiches, salads, or cooking into sauces. It's an indeterminate, tall-growing plant with distinctive flattened, ribbed, beefsteak-type fruits that are juicy and versatile, thriving in sunny conditions but requiring staking.
