Basil Siam Queen Seeds

Basil Siam Queen Seeds

Ocimum basilicum

Item #5025

Annual. Thai basil is known in Thailand as “Horapha”, and is known to the Vietnamese as “Hung Que” (eaten raw with noodle soup in the morning). Siam Queen basil is a distinct improvement over old Thai basils; the yields are impressive with leaves twice the size of other Thai basils, 3" to 4" long by 1 ½" to 2" wide. Perfect variety for containers, and a beautiful addition to flower gardens.

This packet plants one 10-foot row.

When to sow outside: RECOMMENDED. 1 to 2 weeks after average last frost, and when temperatures are warm. Basil is very sensitive to frost.

When to start inside: 6 to 8 weeks before planting outside.

Special sowing instructions: Easy to grow from seed. Wait to sow until nighttime temperatures are above 50° F.

Harvesting: Basil should be harvested before the plant flowers. The leaves have more flavor when harvested in the morning. The young, top leaves taste the best, and should be used fresh; the older leaves may be used for vinegar and pesto. Cut a few stems but never more than 1/3 of the plant. Wash stems, gently shake dry, and strip the leaves off the stem. If there is any chance of temperature dropping to 32° F, harvest crop immediately; basil is very frost sensitive.
