Sparklers Petunia is a dazzling compact variety that produces diminutive purple blooms arranged like clusters of stars across its low, spreading form. This heirloom hybrid reaches about 14 inches wide and 12 inches high, making it exceptionally well-suited to containers, borders, and small garden spaces. Bred over 10 years by Thompson and Morgan after receiving an intriguing white petunia with unusually small flowers, Sparklers earned the prestigious Fleuroselect Novelty award for its distinctive appearance. Plants flower in 70 to 85 days and thrive in full sun with consistent warmth between 75 and 80 degrees Fahrenheit.

Few petunias deliver the visual impact of Sparklers: tiny star-like purple blooms packed densely across a neat, semitrailing mound create an almost ethereal, constellation-like effect. The 10-year breeding program at Thompson and Morgan transformed a single sample of small-flowered white petunia into this eye-catching mix, resulting in a plant that earned international recognition. Its compact stature and prolific flowering make it equally stunning in containers, hanging baskets, or as a low border planting where those diminutive blooms can be appreciated up close.
Sparklers Petunia is grown as an ornamental flower, valued particularly for container gardening, hanging baskets, window boxes, and garden borders where its compact, semitrailing habit and abundant small blooms create dense, colorful displays.
No timeline data available yet for this variety.
Start Sparklers indoors 8 to 10 weeks before your last expected frost date. Sow seeds on the soil surface or press them lightly into moist seed-starting mix, as petunia seeds require light to germinate. Keep the soil at 70 to 75 degrees Fahrenheit and maintain consistent moisture. Seedlings should emerge in 7 to 10 days and be ready to transplant outdoors after the last frost.
Transplant hardened-off seedlings outdoors after the last frost date, when soil has warmed and nighttime temperatures remain above 50 degrees Fahrenheit. Space plants 6 inches apart. Water gently after planting and keep soil evenly moist for the first 2 weeks while plants establish.
Deadhead spent flowers regularly throughout the season to maintain the plant's compact form and encourage continuous blooming. If plants become leggy or overgrown, you can lightly pinch back stems in early summer to promote bushier, more rounded growth; Sparklers' semitrailing habit generally produces a naturally full appearance with minimal intervention.
