Is Nettle a Shiso?

Published in Botanical Differences 3 mins read

No, nettle is not a shiso. While they might occasionally be mistaken for each other due to certain visual similarities, shiso and nettle are distinct plants belonging to different botanical families with unique characteristics and uses.

Understanding the Distinction: Shiso vs. Nettle

Shiso, scientifically known as Perilla frutescens, is a fragrant and distinctively aromatic herb, predominantly celebrated in Japanese cuisine. It features beautiful red or green leaves and emits a bright, herbaceous perfume. Its unique aroma has gained increasing recognition in Western culinary applications in recent years. Nettle, on the other hand, typically refers to plants in the Urtica genus, most commonly Urtica dioica, also known as stinging nettle, which is known for its fine stinging hairs that can cause skin irritation upon contact.

To highlight their differences, consider the following comparison:

Feature Shiso (Perilla frutescens) Nettle (Urtica dioica)
Botanical Family Lamiaceae (Mint family) Urticaceae (Nrticaceae family)
Primary Use Culinary herb, ornamental plant Wild edible, medicinal herb, fiber plant
Leaf Appearance Often red or green, sometimes ruffled, fragrant Green, toothed edges, covered in stinging hairs
Aroma/Scent Bright, herbaceous, distinct (often described as minty, basil-like, or cumin-like) Earthy, green; no distinct fragrance without crushing
Notable Feature Highly aromatic, non-stinging, used fresh or cooked Contains stinging hairs that release irritants upon contact
Common Cuisine Japanese, Korean, Vietnamese European, traditional foraging

Why the Confusion?

The reference indicates that shiso is "sometimes mistaken for stinging nettle." This confusion likely stems from superficial resemblances in leaf shape or growth habit when the plants are not observed closely. Both can grow relatively wild, and their leaf structures might appear somewhat similar at a quick glance, especially to an untrained eye. However, the presence of stinging hairs on nettle, coupled with shiso's unmistakable fragrance and lack of stings, serves as an immediate identifier.

Distinctive Characteristics

Understanding the unique attributes of each plant helps clarify why they are fundamentally different:

Shiso

  • Aromatic Profile: Shiso is highly prized for its vibrant and complex aroma, which can range from notes of mint and basil to cumin and cinnamon, depending on the variety (e.g., green shiso or red shiso).
  • Culinary Versatility: It's a staple in Japanese cuisine, often used to wrap sushi, as a garnish for sashimi, in salads, or pickled to create umeboshi (pickled plums). Its unique flavor profile is being increasingly explored in various contemporary dishes and beverages.
  • Non-Stinging: Despite its sometimes rough appearance, shiso leaves are smooth to the touch and do not cause any irritation.
  • Appearance: Shiso plants can have striking red or green foliage, making them visually appealing as garden plants.

For more information, explore resources on Shiso (Perilla frutescens).

Nettle

  • Stinging Hairs: The most defining characteristic of nettle is the presence of fine, hollow hairs (trichomes) on its leaves and stems that inject histamine and other chemicals upon contact, causing a stinging sensation.
  • Nutritional Value: Despite its sting, nettle is highly nutritious, rich in vitamins, minerals, and antioxidants. It's often consumed cooked (which deactivates the sting), in soups, teas, or as a leafy green vegetable.
  • Traditional Uses: Nettle has a long history of use in traditional medicine and is also used for making textiles and dyes.
  • Growth Habit: Nettle tends to grow in nutrient-rich soils, often found in disturbed areas, woodlands, and along pathways.

In conclusion, while a quick glance might lead to a momentary mix-up, nettle and shiso are botanically distinct species with unique features, aromas, and culinary applications.
