Nufar basil

A variety of sweet basil resistant to downy mildew

Nufar basil is a cultivar of sweet basil (Ocimum basilicum) known for its resistance to downy mildew, a common fungal disease that affects basil plants. This variety is particularly valued in culinary and horticultural applications due to its robust growth and disease resistance.

Description

Nufar basil is characterized by its large, aromatic leaves and vigorous growth habit. The plant typically reaches a height of 18 to 24 inches and spreads about 12 to 18 inches wide. The leaves are bright green, smooth, and slightly cupped, with a strong, sweet aroma typical of sweet basil varieties.

Cultivation

Nufar basil is grown primarily for its leaves, which are used fresh or dried in a variety of culinary dishes. It thrives in warm, sunny environments and requires well-drained soil with consistent moisture. This cultivar is particularly popular among gardeners and commercial growers due to its resistance to downy mildew, a disease that can devastate other basil varieties.

Planting

Nufar basil can be started from seed indoors about 6 to 8 weeks before the last expected frost date. Once the seedlings have developed a few sets of true leaves, they can be transplanted outdoors after the danger of frost has passed. The plants should be spaced about 12 to 18 inches apart to allow for adequate air circulation, which helps prevent fungal diseases.

Care

Regular watering is essential for Nufar basil, especially during dry spells. However, care should be taken to avoid waterlogging, which can lead to root rot. Fertilization with a balanced, all-purpose fertilizer can promote healthy growth, but over-fertilization should be avoided as it can reduce the plant's essential oil content, affecting flavor.

Uses

Nufar basil is widely used in cooking, particularly in Italian cuisine, where it is a key ingredient in dishes such as pesto, caprese salad, and various pasta sauces. The leaves can be used fresh or dried, although fresh leaves are preferred for their superior flavor and aroma.

Pest and Disease Resistance

The primary advantage of Nufar basil over other sweet basil varieties is its resistance to downy mildew, a disease caused by the pathogen Peronospora belbahrii. This resistance makes it a preferred choice for growers in regions where downy mildew is prevalent. While Nufar basil is resistant to this particular disease, it is still susceptible to other common basil pests and diseases, such as aphids, spider mites, and fusarium wilt.
