Tievine

Ipomoea cordatotriloba

Also known as Cotton Morning Glory, Sharppod Morning Glory, Three-Lobed Morning Glory

Tievine is a vigorous trailing or climbing morning glory that quickly blankets fence lines, field margins, and open thickets with slender, twine-forming stems. Its funnel-shaped blossoms range from pale lavender to vibrant purple with a deep violet center, opening in the morning sun and fading by late afternoon. Emerging from an enduring tuberous taproot, it resprouts readily after mowing or winter frosts, making it a remarkably resilient native pioneer plant.

Why interaction risk is high
Seeds and foliage contain alkaloids toxic to pets and livestock; avoid ingestion.
Why it is dangerous
Seeds contain ergoline alkaloids that can induce vomiting, diarrhea, and tremors if ingested by pets or livestock.
How to recognize a risky encounter
Recognized by climbing stems, variable heart-shaped or deeply three-lobed leaves, and lavender to violet trumpets with dark throats.
What to do
Keep curious pets away from seeding pods and wash hands after clearing overgrown vines.
Responsible observation
  • Morning Photography: Photograph blossoms early in the day before intense heat causes flowers to collapse.
  • Root Inspection: Look near the soil surface to spot the swollen perennial taproot anchor.
  • Garden Management: Prune aggressively along fences if attempting to keep it from smothering nearby perennials.
