Basic Information
Common Name: Arugula
Scientific Name: Eruca vesicaria
Native Habitat: Mediterranean Region
History / Discovery / Cultivator
Arugula, scientifically known as Eruca vesicaria, boasts a rich history intertwined with human civilization. Its origins trace back to the Mediterranean region, where it has been cultivated and consumed for millennia. Evidence suggests that the ancient Romans were particularly fond of arugula, valuing it for its peppery flavor and purported aphrodisiac properties. They used it in salads, sauces, and even as a flavoring for oils. The plant’s widespread cultivation throughout the Roman Empire contributed to its dispersal across Europe and North Africa.
During the Middle Ages, arugula continued to be a popular culinary herb, appearing in various recipes and medicinal texts. It was grown in monastery gardens and by commoners alike. However, its popularity waned somewhat during the later centuries, possibly due to the introduction of other, more readily available greens.
In more recent times, arugula has experienced a significant resurgence in popularity, particularly in Western cuisine. This revival can be attributed to several factors, including a growing interest in diverse flavors, a greater awareness of the nutritional benefits of leafy greens, and the efforts of chefs and food writers to reintroduce this ancient herb to modern palates.
While no single individual can be credited with “discovering” arugula (given its long history of use), its renewed prominence can be linked to chefs and farmers who championed its unique flavor and versatility. Today, arugula is grown commercially in many parts of the world and is a common ingredient in salads, pizzas, pasta dishes, and numerous other culinary creations. It has become a staple in farmers’ markets and grocery stores, signifying its lasting appeal and culinary significance. Modern hybridization has led to varieties with varying degrees of peppery flavor and leaf shapes, offering consumers a wider range of options. The plant’s easy cultivation further ensures its continued popularity. The plant’s geographic origins in the Mediterranean have thus led to its global consumption today.

Botanical Insights
Adaptations
Arugula possesses several key adaptations that contribute to its success. Its rapid growth cycle allows it to quickly colonize disturbed areas and take advantage of favorable conditions. The peppery flavor, derived from glucosinolates, acts as a natural deterrent to herbivores, protecting the plant from excessive grazing. Its ability to thrive in relatively poor soils contributes to its adaptability. Finally, its cold-tolerance allows it to grow even in colder climates.
Propagation Methods
Arugula is most commonly propagated by seed. Seeds can be directly sown into the garden or started indoors for transplanting. Another easy method is self-seeding. Allow some plants to bolt and drop seeds, and they will often germinate readily in the following season.
Toxicology
Arugula is generally considered safe for human and pet consumption. However, individuals with allergies to other cruciferous vegetables (such as broccoli, cauliflower, or cabbage) may experience allergic reactions to arugula. The peppery flavor can sometimes cause mild stomach upset in sensitive individuals if consumed in large quantities. Despite the peppery flavor, arugula is non-toxic.
Common Problems
Pests:
- Flea beetles
- Aphids
- Cabbage worms
Diseases:
- Downy mildew
- White rust
Other:
- Bolting (premature flowering) due to heat stress: Provide shade and ensure adequate watering.
- Bitter taste: Can be caused by hot weather or insufficient watering; harvest young leaves for a milder flavor.
- Leaf yellowing: Can be caused by nutrient deficiencies; amend soil with compost or fertilizer.
Rarity & Value
Rarity:
Arugula is not considered rare. It’s widely cultivated and readily available in most markets. However, heirloom or wild varieties might be less common.
Value:
The value of arugula is generally low, as it is easily grown and widely available. Price can fluctuate slightly based on seasonality and local demand. Organic or specialty varieties may command a slightly higher price.
