Here is the Round Black Spanish Radish, Raphanus sativus. It is also known as the Noir Gros Rond d'Hiver. This radish dates back to the 1500's in Europe and grown in the U.S. since the 1800s. It is a Winter Radish that gets to around 4 to 5 inches round or globe shaped and is a HOT radish type. It has a black skin with a bright white flesh inside with a crisp crunchy spicy flavor. The tops of these radishes can grow very tall, about 20 inches tall in fact! We prefer to cook this type of radish rather then eating raw. Radishes can be useful as companion plants for many other crops, probably because their pungent odor deters such insect pests as aphids. This is a great starter vegetable for new gardeners. Open pollinated,  35 to 50 days.

    The timing of radish seed planting depends upon the specific radish variety. Annual or spring radish varieties grow best when sown in the spring two to three weeks before the last average spring frost date when soil temperatures reach 55 degrees Fahrenheit. Annual radishes also grow well when planted in late summer or early fall when temperatures drop below 65 degrees Fahrenheit. Winter or biennial radishes benefit from a mid to late summer planting timed so that they are ready for harvest at the first average fall frost date.

    Radish seeds germinate most readily when exposed to constant temperatures of 55 to 75 degrees Fahrenheit. However, they will sprout at temperatures as low as 40 degrees and as high as 85 degrees. Sowing the seeds 1/4- to 1/2-inch deep and 1 inch apart provides the correct spacing for seedling emergence. Under ideal conditions, radish seeds will germinate within three to four days, but may take as many as 10 days. If planted any deeper or exposed to cooler temperatures, the seeds will take longer to germinate and may not germinate at all.
