Boxwood Basil is a distinctive and versatile herb, known for its compact growth and small, dense leaves that resemble a boxwood shrub. Its appealing form makes it suitable for both ornamental landscaping and culinary uses.
Understanding Boxwood Basil
Boxwood Basil (Ocimum basilicum ‘Boxwood’) is a cultivar of sweet basil. Unlike many basil varieties, it naturally develops a compact, mounding, and bushy form, typically reaching 8 to 14 inches tall and wide. Its leaves are smaller than traditional basil but retain a strong, sweet flavor. This makes it ideal for limited spaces or as an appealing edible plant.
Growing Boxwood Basil
Site Selection and Planting
Boxwood Basil thrives in ample sunlight and well-draining soil. Full sun, meaning at least six hours daily, is ideal for optimal growth and flavor. The soil should be rich in organic matter and drain effectively to prevent waterlogging.
For seeds, sow indoors three to four weeks before the last frost, ensuring soil temperature is around 70°F (21°C). If transplanting starts, wait until nighttime temperatures consistently remain above 50°F (10°C). Space plants 8 to 10 inches apart.
Ongoing Care
Consistent moisture is important for Boxwood Basil, but avoid waterlogging. Provide about one inch of water per week, adjusting for weather and soil type. Container plants may need more frequent watering.
While basil benefits from rich soil, light feeding with a balanced vegetable fertilizer every two weeks supports vigorous growth. To maintain a compact, bushy shape and encourage continuous leaf production, regularly pinch back stems. Removing flower buds prolongs leafy growth, as flowering signals the end of the plant’s productive cycle.
Harvesting Techniques
Regular harvesting encourages more foliage and maintains the desired shape. Leaves can be picked throughout the growing season, typically starting 60 to 90 days after seedlings emerge.
Pinch off stems just above a leaf node; this promotes new branches, leading to a bushier plant and continuous fresh leaves. Avoid removing more than one-third of the plant at any time to prevent stressing it. For best flavor and highest oil content, harvest leaves in the early morning.
Enjoying Boxwood Basil
Boxwood Basil’s strong, sweet flavor makes it a versatile culinary herb. Its small, delicate leaves are ideal for garnishes, providing intense basil flavor without chopping. They are perfect for pestos, salads, marinades, and sauces, and the flavor holds up well in cooked dishes.
Beyond the kitchen, Boxwood Basil offers ornamental appeal due to its neat, compact form. It serves as an attractive edible plant for garden edging, container arrangements, or as a miniature hedge, adding beauty and fragrance to garden spaces.
