Double-flowered
Split Second Morning Glory is a stunning heirloom cultivar of Ipomoea nil that transforms the familiar morning glory into something truly extraordinary. These vigorous vines climb 6 to 10 feet and produce fully double flowers in shades ranging from shell pink to nearly coral, their petals delicately notched and frilled like a peony or parrot tulip. From seed to first bloom takes 84 to 98 days, making it possible to enjoy weeks of spectacular flowering from summer through fall in most regions. This cottage garden favorite thrives in full sun with moderate water and draws pollinators throughout the growing season.

What sets Split Second apart is its dramatic departure from the traditional trumpet-shaped morning glory flower. The fully double blooms have a distinctly ornamental quality, with margins so frilled and notched they resemble a peony more than a typical morning glory. The vigorous vine growth means you'll quickly cover a trellis or arbor with lush foliage and an abundance of these show-stopping flowers. Combined with its reliable 84 to 98-day maturation from seed and long blooming window from June through November, it's a heirloom that rewards patient gardeners with months of visual drama.
Split Second Morning Glory is grown primarily as an ornamental flowering vine for trellises, arbors, and cottage garden displays. The vigorous growth habit and abundant double blooms make it particularly suited to creating living screens, focal points in garden structures, or dramatic vertical accents. Its extended bloom window from summer into fall extends the ornamental interest well into the season.
Sow seeds indoors about 4 weeks before your last frost date in pots, keeping them at 65 to 80°F. Cover the pots with a humidity dome to retain moisture until germination, which typically occurs within 5 to 14 days. Nick or file the seed coat before soaking seeds in warm water for 24 hours to improve germination success.
Transplant seedlings outdoors about 2 weeks after your last frost date, once soil temperatures have warmed. Harden off plants by gradually exposing them to outdoor conditions over several days before planting them out.
