Purple Shiso
Purple Shiso, also known as Perilla frutescens var. Crispa, is a unique herb from Eastern Asia, particularly China, Korea, Japan, India, and Thailand, that belongs to the mint family. The vibrant purple or green color and elegant ruffled edges of this herb set it apart, making it a striking addition to any garden or dish.
Shiso's unique characteristics set it apart. The leaves come in a range of colors, from green to purple, particularly when grown in shaded areas, and emit a refreshing minty scent when crushed. Additionally, shiso plants produce slender, hairy spikes known as racemes, which bear pairs of purple or white flowers. The stems of shiso plants are square in shape and covered in short hairs.
In terms of flavor, purple shiso offers a distinctive taste that combines the refreshing qualities of mint with the spiciness of ginger. Some even detect hints of herbs, licorice, or citrus notes in its profile, adding to its complexity. This makes it the perfect addition to any type of salad.
Popular in Asian cuisine, purple shiso, also known as Chinese basil or purple perilla, is commonly used to add color and flavor to vinegar and rice. It is often used in fried rice, sushi, and ramen noodles. It can also be cultivated as micro-leaves for inclusion in salads and used as a garnish on pasta, pizza, and soups.
Shiso is an excellent source of calcium, potassium, iron, and vitamins A, B2, and C. It is also rich in omega-3 fatty acids and rosmarinic acid, which possess potent anti-inflammatory properties. These qualities make shiso a healthy and beneficial choice for human consumption.
The shiso leaves contain calcium, iron, and vitamin C, making them good sources of antioxidants. Used in traditional Chinese medicine for asthma, colds, and flu symptoms, shiso seeds are high in omega-3s and support a healthy immune system.
To grow purple shiso, plant it in nutrient-rich, well-drained soil under full sun. Water sparingly, only when the soil is dry, and cover the plants for protection during the winter. Shiso readily self-seeds, so if you allow the seeds to drop off the plant and into the soil, it will continue to grow year after year. I can attest to this personally: I planted just a couple of purple shiso plants in my garden several years ago, and now they're growing everywhere.
It is worth noting that this plant is known to be safe for consumption by humans, birds, livestock, dogs, and cats.
As with any herb or supplement, it's wise to consult with your healthcare provider if you're taking any medications.
