Perilla frutescens var. crispa. Red Perilla shiso seeds grow into substantial plants with wide, deep purple leaves. The dark ruby leaves of this sharply flavoured Asian herb have nicely frilled edges. They look a little bit like stinging nettle leaves, but rounder, and without any prickles. Grow as a bright-red micro-green, or let the plants mature and enjoy the leaves inpho, salad rolls, or other dishes. Shiso makes a wonderful pairing with unctuous dishes like sushi, and it combines beautifully with cilantro, mint, Thai basil and fresh lettuce leaves. Shiso has a very similar growing season to basil, and performs just as well in containers as in the garden bed. Provide full sun and well drained soil.
