Description

A celebrated variety of Thai basil, Ocimum basilicum var. thyrsiflora ‘Siam Queen’ is prized for its bold, sweet-spicy flavor and powerful fragrance of anise, clove, and mint. The lush, glossy green leaves and striking purple stems make it both a culinary powerhouse and a visual delight in the garden. Its distinctive aroma defines Southeast Asian dishes, carrying that unmistakable Thai basil essence used in curries, noodle bowls, and fresh salads.

Plants grow 24–30 inches tall with strong, upright stems and dense foliage that resists heat and bolting. The showy lavender blossoms rise above the leaves, drawing pollinators while ensuring continued harvest throughout the warm months. Its flavor holds beautifully under heat, infusing cooked dishes without losing its bright, spicy complexity.

An All-America Selections winner, Siam Queen represents the finest of Thai basil breeding—robust, aromatic, and true to its roots. It remains the standard for authentic Thai cuisine and a must-grow for gardeners seeking both beauty and boldness in flavor.
