Thai basil with larger leaves. Edible ornamental with showy flowers. Very uniform, upright habit. Flat, 2-3" long leaves that are larger than typical Thai types; purple stems and dark, purple-red flower bracts. Cinnamon/clove flavor with hints of anise. Slower growing and slow to bolt; needs a long, warm season for cut-flower use. Has demonstrated very good downy mildew tolerance in our field trials.
SOIL REQUIREMENTS:Moderately rich, moist soil. Basil is not drought tolerant and can be damaged by heat stress. Regular moisture throughout the growing season helps to ensure a good crop.
HARDINESS ZONES: Annual.
HARVEST: Begin light harvesting after plants have become established. It is best done in the early morning when the temperature is cooler and the leaves are less likely to wilt. A full harvest should be completed just before the plants start to flower. Cut the entire plant 4-6" above the ground to promote a second growth. Leaves are easily bruised when picking, so handle carefully. Do not store at a temperature less than 50°F (10°C).
