Superbena® Sparkling Amethyst™ (Verbena) is a high-performance, award-winning variety celebrated for its large, multi-tonal flower clusters and exceptional disease resistance. Unlike traditional verbenas that are prone to powdery mildew, the Superbena series is bred to stay lush and green all season. The "Sparkling" designation refers to its unique bicolor pattern—vivid amethyst-purple petals with a distinct white star-shaped center—creating a "twinkling" effect in the garden.
Mature size: 4–12 inches in height; spreads or trails up to 18–30 inches.
Flower: Large, rounded clusters (umbels) of bicolor amethyst-purple and white flowers; blooms continuously from planting until frost.
Foliage: Deep green, lanceolate leaves with a slightly serrated edge and a textured, "quilted" surface.
Hardiness: Annual; perennial in USDA zones 10–11.
This plant is a sun-lover and requires Full Sun (at least 6 hours of direct light daily) to thrive. While it can survive in partial sun, the flower production will be significantly lower, and the stems may become thin and stretched.
Superbenas are relatively thirsty plants. They require consistent moisture and should be watered when the top of the soil feels dry to the touch. While they have better drought tolerance than petunias once established, they should not be allowed to wilt frequently, as this can interrupt the bloom cycle.
Requires rich, well-draining soil. It is highly adaptable but performs best in a high-quality potting mix (for containers) or garden soil amended with organic matter. Proper drainage is essential to prevent root rot, particularly in the early spring or late fall.
To sustain its vigorous growth and massive flower clusters, apply a balanced water-soluble fertilizer every 1–2 weeks. A slow-release fertilizer at the time of planting is also highly recommended to provide a steady baseline of nutrients.
One of the best features of Superbena is that it is self-cleaning, so deadheading is not required for reblooming. However, because it is so vigorous, it may benefit from a mid-summer trim (removing about 20% of the growth) to encourage new branching and a tidier habit for the second half of the season.
Superbena Sparkling Amethyst is a versatile "spiller" and "filler":
Hanging Baskets and Containers: It creates a massive, trailing skirt of color.
Landscape Groundcover: Its spreading habit makes it an excellent choice for the front of garden borders, where it will quickly knit together to fill open spaces.
Pollinator Gardens: The large flower clusters are a magnet for butterflies and bees.
Superbena Sparkling Amethyst is a powerhouse of color and reliability. Its striking bicolor blooms and robust resistance to heat and mildew make it a top-tier choice for gardeners who want high-impact, purple-hued displays that remain healthy and vibrant from spring through the first hard frost.
