Verbena hybrid – Superbena® Red
Dead-Heading Not Necessary
Self-cleaning, no deadheading necessary.
Superbena are our most vigorous, heat tolerant, and mildew tolerant series. While always great in containers they are also fantastic in landscape beds. They can tolerate dry soils and lower fertility. Normally either an application of slow release fertilizer or amending with compost is enough to keep them happy and blooming in landscape beds. They shouldnt need to be trimmed back but can be given a haircut a trim back using a sharp pair of scissors or pruning shears at any time. While naturally well branched, trimming them back will encourage additional branching, fuller plants, and ultimately more flowers. I usually give them a very slight trim as I am transplanting to boost branching.
An application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.
Great for use in both containers of all types and landscapes.

Planting and Timing Information
Early Spring through Fall Finish. Standard PPP. Best in 6" and larger pots, except for Superbena Royales and Superbena Sparkling varieties which work great in 4.5" or larger.
Finishing Times [weeks]
4-5" and Quart Pot : 4-6
6" and Gallon Pot : 5-7
7-9" Pot : 7-9
10-12" and Two Gallon Pot : 8-12
Pinching and Growth Regulators
For all sizes of containers, pinch the liner 1–2 weeks after transplant; for containers larger than 6” and for hanging baskets, trim around the edge of the container as needed prior to spacing or hanging of the baskets.
Sumagic at 5-10 ppm may be used to keep neighboring pots from growing into each other. Growth can be controlled using lower temperatures. Superbena Royales and Superbena Sparkling varieties will need less PGR manipulation and will be easier for small pot production.
Pest and Disease Management
General pest and disease practices as listed in notes. Powdery Mildew can be a problem for verbena. Proper air circulation, humidity control and water management will aid in control and prevention. A broad spectrum fungicide application two after transplanting is highly suggested. Good sanitation practices include keeping greenhouses clean at all times, eliminating weeds and debris, disinfecting equipment in greenhouses as often as possible and keeping hose ends off of the greenhouse floor. Good water management practices are critical for good, healthy plant growth.
-High light in production is essential. -200 ppm fertilizer is optimal -Superbena is our most vigorous series of Verbenas. -Superbena Royale and Superbena Sparkling varieties have more controlled growth and will work more easily in smaller pot sizes as well as filling larger pot sizes. -Superbenas are our most vigorous Verbena series and are our best series in very hot environments. Low pH and severe dry down can cause Iron toxicity if supplemental Iron has been applied. -Superbena Royales and Superbena Sparkling are more compact, with great flower coverage. They will need less PGR manipulation and will be easier in small pot production than other Superbenas.
