- Annie’s G.Verified BuyerRated 5 out of 5 stars5/4/26Beautiful vibrant pink center!
We love these radishes. They create instant visual appeal in anything you use them in! We love to combine with kale in a salad, on avocado toast, or as a topper on nachos with some garden-fresh cilantro. Be sure to plant them out in the cool season. They don’t tolerate heat well, and take a good two months (and some change) to mature. I planted in late February in my zone 7 garden, with plants ready in late April and early May.

These "watermelon" radishes were very easy to grow. I planted them in my Fall/Winter garden in Atlanta (7b). I cut them both ways so you can see different views of this radish. They are very pretty when you grate them into salads. I should have thinned them more so mine did not get super big. Rookie mistake which I will correct when I plant these for spring/summer.

Beautiful radishes that grow well in Wisconsin’s fall weather. My son’s girlfriend also had success in Denver.
