Siam Queen Thai Basil

The Siam Queen Thai Basil is the 1997 All-America Selections winner. The purple stems, large dark green leaves, and pink-violet flowers make for a lovely basil with a tangy flavor, plus a spicy hint of licorice. Siam Queen Thai Basil plants are compact, great for containers and have a showy ornamental value too. An early maturing variety.

Harvest: Start when the plants are 6-8”, picking leaves as needed. Harvest often to keep the plant producing new leaves. Freeze or dry to preserve 

Uses: Culinary and medicinal, containers, flowers attract pollinators and beneficials

Care: Siam Queen Thai Basile needs fertile soil, amended with compost and/or added organic fertilizer. Basil does not like to dry out, keep well watered for optimum growth, mulching will help retain moisture. 

Tips: Pinch seedlings back to encourage branching and increase leaf production. Pinching off the flowers helps the plant continue producing leaves. We like to pinch off flowers on some plants and leave flowers on others for the pollinators. Flowers are also nice in mixed bouquets. Try growing basil indoors on the windowsill or under grow lights. Growing basil as a micro green is an easy way to enjoy fresh basil during the winter months.
