Botanical nameOcimum basilicum 'Siam Queen'

‘Siam Queen Thai’ basil is a fragrant annual herb, known for its typical Thai basil flavor with spicy, anise, and slightly sweet notes. Its dark green foliage, purple stems, and mauve flower spikes also give it great ornamental value in pots, herb planters, urban gardens, and edible flowerbeds. It is an ideal variety for lovers of Asian cuisine, as it retains its aroma well in hot dishes such as stir-fries, curries, soups, marinades, and noodle dishes.

Easy to grow, ‘Siam Queen Thai’ basil prefers a warm, sunny, and wind-protected location, in fertile, light, and well-drained soil. It grows very well in containers on a terrace, balcony, or near the kitchen, where its leaves can be harvested fresh as needed. Regular watering helps maintain tender and flavorful foliage, while avoiding excess water around the roots. To prolong the harvest, it is recommended to pinch the tips of the stems and remove some of the flowers if the main goal is leaf production.

Both aromatic, decorative, and very productive, ‘Siam Queen Thai’ basil is an excellent choice for creating a gourmet garden with more exotic flavors. Its flowers attract pollinators and add a colorful touch to edible arrangements, while its fragrant foliage allows you to cook fresh and flavorful dishes throughout the season. It is an essential variety to enrich a vegetable garden, herb garden, or sunny container with a useful, elegant, and characterful plant.
