When to Plant Trumpet Vine, Hummingbird Vine, and Morning Glory in Zone 7

Northern Mississippi (Zone 7a/7b) timing for three popular vines:

Morning Glory (Ipomoea purpurea) – Annual

Direct sow: After last frost (early–mid April), ½″ deep, 8″ apart. Full sun, lean soil (rich soil = leaves, few flowers).
Indoor start: 4–6 weeks before last frost in 3″ peat pots. Nick seed coat or soak overnight to speed germination. Transplant pot-and-all to avoid root disturbance.
Note: Self-seeds aggressively; deadhead to control spread.

Seeds: Sow in fall (natural stratification) or spring after cold-moist stratification (60 days in fridge).
Cuttings: Softwood cuttings in early summer root easily.
Warning: Extremely vigorous, spreads by suckers and seeds. Plant only where contained by mowing, pavement, or a root barrier.

Morning glory gives quick annual color; trumpet vine is a permanent, high-maintenance commitment.
