Overview

The fastest vegetable from seed to table, some radish varieties are ready to harvest in just 21 days. This makes them the perfect crop for impatient gardeners, children's gardens, and interplanting between slower-growing vegetables. Beyond the familiar small red globe, radishes come in an astonishing variety — from watermelon radishes with green exteriors and hot-pink flesh to giant daikon and black Spanish storage types.
