HEIRLOOM. Bull's Blood has the reddest foliage we have ever seen. The earliest thinnings spark up spring and fall salads with a leaf color as richly dark red as radicchio. As the roots enlarge, the baby beets are also delicious cooked and mixed with salad. The small sweet red roots are best when harvested young. When sowing, mix beet seeds with fast-sprouting radish seeds to mark the rows. Grows best in cool weather and full sun. Certified Organic Seed.
