Supertunia® Royal Magenta® is a classic, high-performance petunia that has long been a staple of the Proven Winners lineup. It is celebrated for its incredibly deep, saturated magenta-purple flowers and its reliable, vigorous growth habit. This variety is specifically bred to be weather-resistant, standing up to heat and rain far better than older petunia cultivars, ensuring the garden remains vibrant from spring through the autumn season.
Mature size: 6–12 inches in height; spreads or trails up to 18–24 inches.
Flower: Large, velvet-textured blooms in a brilliant, glowing royal magenta; features a continuous bloom cycle without the need for manual intervention.
Foliage: Bright green, ovate leaves that are slightly sticky to the touch; the foliage remains dense and provides a lush backdrop for the vivid flowers.
Hardiness: Typically grown as an annual; perennial in USDA zones 10–11.
This plant performs best in Full Sun (6+ hours of direct sunlight per day). High light levels are essential to maintain the intense saturation of the magenta pigment and to keep the plant’s habit tight and mounded.
Requires consistent moisture to sustain its heavy bloom production. While it is more drought-tolerant than some annuals, it should not be allowed to wilt. In containers, daily watering is standard during the summer; in landscape beds, deep watering 2–3 times a week is usually sufficient.
Thrives in loose, well-drained soil with plenty of organic matter. Like most Supertunias, it prefers a slightly acidic soil pH (5.5–5.8). If the soil is too alkaline, the leaves may show signs of chlorosis (yellowing).
To keep the plant "power blooming," it requires frequent fertilization. Use a water-soluble, high-quality fertilizer every 1–2 weeks. For landscape plantings, a time-release fertilizer applied at the start of the season is highly recommended.
Supertunia Royal Magenta is self-cleaning, meaning it sheds its spent blooms naturally and does not require deadheading. To maintain a tidy shape, especially in containers, you can trim the ends of the stems back by a few inches in mid-summer to encourage branching and a fuller center.
The bold color of Royal Magenta makes it a versatile tool for various design styles:
Hanging Baskets: It creates a lush, trailing curtain of color that can reach up to two feet in length.
High-Contrast Combinations: Pairs exceptionally well with chartreuse-colored foliage, such as Sweet Potato Vine 'Marguerite' or Lemon Coral® Sedum.
Mass Bedding: Provides a uniform, vibrant carpet of color when used as a seasonal groundcover in garden borders.
Supertunia Royal Magenta is a quintessential garden performer that combines "royal" color with working-class durability. Its ability to maintain its deep, jewel-toned flowers through the peak of summer heat makes it an indispensable choice for both novice gardeners and professional landscapers.
