OCIMUM basilicum 'Summerlong'

Family

Lamiaceae

Botanical Name

OCIMUM basilicum 'Summerlong'

Plant Common Name

Basil, Summerlong Basil

General Description

Bearing a summer-long bounty of zesty, fragrant leaves on compact, bolt-resistant plants, this Burpee introduction is well suited for both ornamental and culinary plantings. It is one of hundreds of selections of Ocimum basilicum, an annual or short-lived perennial from tropical Asia that has long been cultivated for its aromatic, flavorful leaves.

The fragrant, bright-green, oval leaves of this basil are densely borne on low, shrubby, mounded plants. The robustly flavored leaves taste great in salads, pesto or pasta sauce. Although less likely to flower (or "bolt") than most basil varieties, 'Summerlong' may bear spikes of small, two-lipped, pale purple blooms in the heat of summer. Flowering causes the leaves to deteriorate in appearance and flavor, so pinch back any flower buds.

Basil requires full sun and fertile to average, well-drained soil. Grow it as a spring and summer annual in cooler zones and a year-round perennial in warmer locations. Water regularly for good growth and harvest the leaves often to encourage the continued growth of tender shoots and leaves. Basil is the perfect companion plant for tomatoes, so consider planting a few at the base of their cages or trellises. This cultivar is propagated from seed.
