What is an heirloom tomato? Many gardeners have heard the term but don't really know what it means. Happily, it's an easy definition: a variety that has been passed down from gardener to gardener. Unlike modern hybrid varieties, heirloom tomatoes come true from seed, making them easy to share.
The main reason to choose heirloom tomato varieties is the flavor. There's no one taste; you'll find a wide range of flavors in the heirloom-tomato world. But many of these varieties are prized for having an old-time taste -- they're a far cry from tomatoes at the grocery store, or even from many modern hybrids like 'Better Boy' or 'Early Girl'.
Perhaps the most famous heirloom tomato, 'Brandywine' is a classic strain that many experts rank as the best-tasting tomato around. It features large red fruits -- to 2 pounds each -- and dates to the late 1800s. 'Brandywine' is an indeterminate variety (meaning it continues to grow after it begins producing fruit), and its fruit ripens about 85 days from transplanting.
Heirloom Tomato Tip: Heirloom tomatoes aren't necessarily organic. Organic means growing plants without the aid of synthetic fertilizers, herbicides, etc. Many gardeners prefer to grow their tomatoes organically, but not all organic tomatoes are heirloom, and not all heirloom tomatoes are grown organically.
