Overview

Lemon verbena is a flowering shrub in the verbena family Verbenaceae, native to northwestern Argentina and southern Bolivia. Its leaves carry a strong, clean lemon aroma with floral undertones, and the flavor is citrusy without the acidity of actual lemon juice. The plant is cultivated widely in South America and has been naturalized in many warm-climate regions.

Origin and history

Lemon verbena is native to the southern Andes, specifically northwestern Argentina and southern Bolivia [1]. It was brought to Europe by Spanish and Portuguese colonizers in the 17th century, where it became a popular garden and medicinal plant [1]. In Peru, the herb is known as hierba luisa or cedrón and has been integrated into everyday cooking and tea culture. The plant’s scientific name is contested; it is classified as both Aloysia triphylla and Aloysia citrodora in different botanical references.

Varieties and aliases

  • Hierba luisa (Peru, Spanish-speaking Latin America)
  • Cedrón (Peru, parts of South America)
  • Lemon beebrush (English common name)
  • Aloysia citrodora (synonymous scientific name)
  • Aloysia triphylla (synonymous scientific name)

Culinary uses

Lemon verbena is most commonly prepared as a hot infusion, known in Peru as mate de hierbaluisa, a light citrusy tea often served at breakfast, especially in coastal and sierra households as noted in one catalog entry [2]. In Peruvian chifa restaurants, it appears as té chino con hierba luisa, a tea that blends Chinese tea with fresh lemon verbena leaves [3]. The herb is also used to flavor desserts, sorbets, and cocktails, and can be steeped in milk or cream for custards and panna cotta. Fresh leaves are sometimes chopped into salads or used as a garnish.

Cross-cuisine context

Lemon verbena is widely cited as the primary flavoring agent for Inca Kola, a bright golden-yellow soft drink created in 1935 by British immigrant Joseph Robinson Lindley in the Rímac district of Lima [4].

Notes for cooks

  • Fresh lemon verbena leaves are significantly more aromatic than dried. Store fresh leaves in a damp paper towel inside a sealed bag in the refrigerator for up to a week.
  • Dried lemon verbena can substitute for fresh in infusions at a ratio of roughly 1 tablespoon dried to 3 tablespoons fresh.
  • The leaves are tough and fibrous; they are typically steeped and removed before serving, not eaten whole.
