Ornamental Basil - Key Growing Information

Bouquet of basil flowers, useful as a fragrant filler or spike element in floral arrangements.

DAYS TO GERMINATION:

Seedlings appear in 5–10 days at 65–70°F (18–21°C).

SOWING:

Sowing in place is recommended, in spring once the soil has warmed after the last frost. Plant 2–3 seeds per inch in rows 18" apart and firm the soil over them, since heavy rain can push the seed up and out. Thinning isn't required, but plants spaced 4–8" apart grow fuller and healthier. For transplants, start seed indoors about 6 weeks before planting out, ¼" deep at 70°F (21°C) for best germination. Plant out when seedlings have 3–4 pairs of leaves, 4–8" apart in rows 18" apart.

LIGHT PREFERENCE:

Full sun.

SOIL REQUIREMENTS:

Moderately rich, moist soil. Basil can't take drought and suffers in heat stress, so keep it evenly watered all season for a good crop.

PLANT SPACING:

Space plants 4–8" apart.

HARDINESS ZONES:

Grown as an annual.

HARVEST:

Cut in the cool of early morning, when leaves are less prone to wilting, and handle gently since they bruise easily. Don't store below 50°F (10°C).
For fresh use, cut once the flowers start to open.
For drying, cut when the flowers are fully open and air-dry. Cut early in the day while it's cool so the leaves wilt less, and handle them gently to avoid bruising. Don't store below 50°F (10°C).

USES:

Cut flowers, bedding and edible flowers.

SCIENTIFIC NAME:

Ocimum basilicum
