Landscape Attributes

Superbena® Stormburst Verbena is an herbaceous perennial with a trailing habit of growth, eventually spilling over the edges of hanging baskets and containers. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This plant will require occasional maintenance and upkeep. Trim off the flower heads after they fade and die to encourage more blooms late into the season. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Superbena® Stormburst Verbena is recommended for the following landscape applications;

• Mass Planting
• Border Edging
• General Garden Use
• Groundcover
• Container Planting
• Hanging Baskets

Planting & Growing

Superbena® Stormburst Verbena will grow to be about 10 inches tall at maturity, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 12 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 3 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It may require supplemental watering during periods of drought or extended heat. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid. It can be propagated by cuttings; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Superbena® Stormburst Verbena is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. Because of its trailing habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
