Siam Queen Basil, Heirloom Herb Seeds

Siam Queen Basil, Heirloom Herb Seeds — The Award-Winning Thai Basil With Licorice Flavor and Ornamental Beauty

Siam Queen is the Thai basil that earned an All-America Selections award — and it shows. More tender and aromatic than sweet basil, Siam Queen produces large 3–4 inch green leaves on striking purple stems with clusters of deep purple flowers that are as ornamental as they are edible. The flavor is sweet and spicy with pronounced licorice overtones, making it exceptional in both Italian and Thai cooking. Late-flowering habit means longer leaf harvests and higher yields than most basil varieties. Vigorous, easy to grow, and remarkably free of disease and pest problems. 72–90 days.

Growing Notes

Start indoors 4–6 weeks before last frost, or direct sow outdoors after frost danger has passed. Sow seeds ¼ inch deep in fertile, well-draining soil. Transplant or thin to 12–18 inches apart in full sun. Water consistently — do not let soil dry out. Pinch flower buds to extend leaf harvest. Pick young shoots regularly to encourage bushy growth.
