    Features

    Supertunia petunias are vigorous with slightly mounded habits that function as both fillers and spillers in containers.  They are also excellent landscape plants, best suited to be placed near the front of beds.  They have medium to large sized flowers.

    One look and you’ll know why this Supertunia is so special. Its incredible vigor is impressive, but the luminescent glow which emanates from the center of the princess purple flowers will keep buyers coming back for more.

    Stunning purple blooms feature a luminescent glow which emanates from the center, not unlike the color patterns found in some morning glory flowers. It’s a new pattern for the Supertunia line, and one that we expect exciting things to come from in the future. No deadheading is needed to keep it in bloom from spring to fall. In addition to gorgeous flowers, the vigor of this plant is incredible, nearly rivaling Supertunia Vista petunias but with a more trailing habit. Combine it with other medium to high vigor plants in large hanging baskets and upright containers or use it as a flowering groundcover for landscapes.

    Plants may be trimmed back with a sharp pair of scissors or pruning shears at anytime, although this is not usually necessary. Plants may flush out of flower if night temperatures begin to stay in the upper 70's or above. If this happens a light trim to shape them would be good. The trim will increase branching and will result in more flowers once the temperatures fall and the plants begin flowering again.

    A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

    Maintenance Notes: 

    These are heat tolerant plants, that aren't particularly fussy and need little routine maintenance. They will perform best if an application of controlled release fertilizer is included at the time of planting. This applies to both landscape and container plantings. Supertunias are heavy feeders, but a single dose is usually sufficient for landscape beds in most climates. If you have a very long season, a second application of controlled release plant food should be considered for landscape plantings. In general, containers need to be fed more than landscape plants. Supertunias in containers will need to be fed more regularly to be their absolute best. A second application of a controlled release fertilizer can be applied about every two months to container plants, which will help. However, for the very best performance I find regularly applying water soluble fertilizer starting about two months after the containers are planted gives the best results.  These extra applications of plant food really makes a difference in performance through the summer.

    If your plant begins to look open or a bit tired, an allover trim can be beneficial.  Use a sharp pair of scissors or pruning shears to trim back up to 1/3 of the volume of the plant. I pair any trim with a dose of water soluble fertilizer to provide instant energy to help kickstart new growth, branching and flowering. Your plant will take a week to recover from the trim, but the end result is a fuller plant with more blooms going forward. You may repeat the trim as needed through the season.
