The colorful Verbena in the Superbena® Series are best known for their showy flower clusters, vigorous wide-spreading habit, and good mildew resistance. Superbena® Large Lilac Blue bears masses of lavender flowers.
The low, mounding or trailing stems of this tender perennial are clothed with oval, toothed, mint-like leaves. The hemispherical clusters of tubular, flaring, five-lobed blooms continue all year in the absence of frost and severe heat. Butterflies flock to the flowers. Deadheading of this sterile cultivar is unnecessary, but occasional pinching or trimming will promote branching and flowering.
Like many other verbenas, this cultivar tolerates drought, heat and humidity. It prefers full sun and moderately fertile, amply drained soil. Too much shade results in leggy sparsely flowered plants. Powdery mildew is a problem for most Verbena, but those in this series are resistant. Still, good airflow and care will help plants stay healthy. They are superb for bedding and planters, and spectacular cascading from hanging baskets.

When you are ready to learn how to grow verbena, you’ll want to locate this tough specimen where it gets 8 to 10 hours of sun each day. The verbena flower is not particular about soil, except that it must be well-draining. Poor soil is acceptable for verbena growing conditions. Perennial varieties of the verbena flower are often lost when planted in soil that becomes soggy following heavy winter snow or spring rain. Good drainage can offset this problem. Improve drainage before planting verbena by working in well composted, organic material.
While the verbena flower is drought resistant, the blooms are improved with regular watering of an inch or so each week. Water verbena plants at the base to avoid wetting the foliage. However, verbena plant care may not include weekly water if rainfall in your area has reached an inch or more.
A limited application of complete, slow-release fertilizer is also a part of verbena plant care. Apply in spring and again following the occasional trims needed for optimum bloom.
When planted in proper verbena growing conditions, expect blooms the first season. Continued blooms throughout the summer are possible if the gardener keeps the plant trimmed back. Some are hesitant to remove parts of the plant regularly, but this is often necessary when planting verbena for summer blooms. When blooms slow, trim the entire plant back by one fourth for a new show of flowers in 2 to 3 weeks. Fertilize lightly following the trim and water well. Repeat this step as needed when learning how to grow verbena successfully.
When planting verbena, remember to water, fertilize and trim for long lasting color in the summer garden and beyond.
