Originating in Southeast Asian, Siam Queen Basil is a heat-loving tropical heirloom. The plants produce into late summer with active growth, developing rich-green leaves with purple stems. Harvest is ideal when leaves grow to 4” and give off a strong clove scent, but before the plant blooms. This large-leaf type of basil with anise flavor will continue to provide spicy licorice flavor until the first frost arrives. By early fall, purple clumps of delicate and edible blooms will appear.

Often grown for its aromatic properties as an ornamental garden, it makes a wonderful companion plant to many vegetables in the garden. The strong aroma is a deterrent to many pests and the flowers are a pollinator magnet.

This large-leaf tropical herb is often grown as an ornamental garden.  With its strong anise flavor and active growth, Siam Queen Basil makes an ideal ingredient in Thai cuisine or fresh zesty salads. A favorite in both our garden and our table!

Plants grow 20-24” tall as compact bushes and thrive in containers.

Care and Growing Instructions

Sowing Seeds Indoors

Sow Thai Siam Queen Basil seeds indoors 6-8 weeks before the last frost in spring
Sow thai basil seeds ¼ inches deep in seed-starting formula
Keep the soil evenly moist at 70 degrees F
Seedlings emerge in 7-14 days
As soon as basil seedlings emerge, provide plenty of natural light on a sunny windowsill or grow under fluorescent light on a 12 hours cycle.
Transplant basil plants in the garden after a period of “hardening”, increasing the seedling’s exposure to sunlight gradually over a one-week period. Seedlings are ready for transplants when they have 3 to 4 true leaves.
Do not expose basil plants or seedlings to frost.

Sowing Seeds Outdoors

Direct sow Basil seeds in average soil in full sun after all danger of frost has passed when the soil temperature is at least 60 degrees F. Basil grows best in fine, well-draining soil of average fertility.
Sow basil seeds evenly and cover with ¼ inches of fine soil.
Firm the soil lightly and keep evenly moist.
Seedlings will emerge in 7-14 days, possibly longer in cooler soils.

Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients. Mulching the growing area helps the soil retain moisture and prevents weed seeds from germinating.
For basil, an organic mulch of aged bark, weed-seed free straw or shredded leaves is ideal. Mulching has many benefits including added organic matter and fertility as it will improve the soil as mulch breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
Keep basil plants well-watered during the growing season, especially during dry spells. Keep the soil moist but not saturated. Basil plants should not be allowed to dry out.
Do not harvest too much of the plant at one time as this may weaken the plant.
