Propagating Hummingbird Vine (Trumpet Creeper) from Seeds and Cuttings

The term “hummingbird vine” can refer to two different plants. Knowing which you have determines the best propagation method.

Cypress Vine (Ipomoea quamoclit) – Annual

This delicate, ferny-leaved vine with small red tubular flowers reseeds readily. Use seeds, not cuttings. Collect black seeds from the round capsules after they dry. Sow directly in spring after frost, or start indoors 4–6 weeks early. No stratification needed.

Trumpet Creeper (Campsis radicans) – Perennial, Often Invasive

This woody vine has large orange trumpet flowers and can be aggressive. Check with your local extension office before planting. Propagation options:

• Seeds: Collect ripe seeds, wrap in damp paper towel, refrigerate 3 months, then sow in warmth.
• Root cuttings: Dig 4–6 inch root sections in late winter; replant horizontally.
• Softwood cuttings: Take 6-inch tip cuttings in spring, remove lower leaves, dip in rooting hormone, root in wet sand under humidity dome.
• Suckers/layering: Dig rooted suckers from the base or bend a low branch to the ground, wound it, and bury to root.

Important Note

Trumpet creeper is considered invasive in many areas. Consider native alternatives like coral honeysuckle (Lonicera sempervirens) for hummingbird appeal without the spread.
