Brassica juncea 27 days (baby leaf). These sibling mustards are a very attractive pair of deeply toothed and super wavy greens with a pleasant, mild mustard flavor. Plant them both for the striking contrast of Joe’s bright green to Lizzy’s purple and the added loft and spice to salad mixes. Terrific for baby leaf mixes, but the mature plants have great field-holding and bolt resistance for a long harvest window of full-sized leaves.
