- Species and varieties: Verbena is a genus in the family Verbenaceae. White verbena (Verbena hybrida) is a popular variety known for its clusters of small, white flowers. Other varieties of verbena include purple, red, and pink flowering types.
- Hybrid or heirloom: White verbena seeds are typically hybrid varieties, bred for their specific color and growth characteristics. Hybrid seeds are often chosen for their vigor, uniformity, and disease resistance.
- Pruning and training: Regular deadheading of spent flowers encourages continuous blooming. Light pruning can help maintain the plant's shape and promote bushier growth. In perennial zones, cutting back the plant in late winter or early spring can rejuvenate growth.
- Fertilization needs: White verbena benefits from a balanced, slow-release fertilizer applied at planting time. During the growing season, a monthly application of a water-soluble fertilizer can support vigorous growth and abundant flowering. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
- Hardiness zones: White verbena is suitable for USDA hardiness zones 7-11. In these zones, the plant can be grown as a perennial. In cooler climates, it is often grown as an annual.
- Climate requirements: White verbena thrives in full sun and well-drained soil. It prefers a warm climate and can tolerate drought conditions once established. It is important to avoid overly wet conditions, as this can lead to root rot.
