Trumpet vine, also known as trumpet creeper, produces clusters of trumped-shaped, orange flowers that are beloved by pollinators. These vines prefer mild climates, grow in most soil types, and thrive in full sunlight. In fact, trumpet vine is an aggressive spreader that should be grown with caution.
Additionally, trumpet vine is mildly toxic to people.

Trumpet Vine Care
Trumpet vines require little care in order to thrive. Here are the main care requirements for trumpet vine:
Choose a location with partial or full sunlight.
Don't put too much thought into the soil, as trumpet vine isn't picky with soil type.
Water occasionally or during periods of drought.
No supplemental fertilizing needed.
Light: Trumpet vines can grow in full sun to partial shade. Full sun, meaning at least six hours of direct sunlight on most days, will produce the best flowering.
Soil: These vines can tolerate a wide range of soil types, including sandy, loamy, and clay soils, and have a natural affinity for soils that are moist but well-drained. In native locations, they are often found in seasonal swamps and forest thickets.
Water: Trumpet vines like a moderate amount of soil moisture but have good drought tolerance. In general, they only need watering when there are obvious signs of wilt and withering. In most climates, the typical rainfall will be sufficient to keep the plants healthy. About 1 inch of water per week—through a combination of rainfall and/or irrigation—is entirely sufficient for good plant performance.
Temperature and Humidity: This plant's natural range is the hot, humid Southeastern United States, but it is hardy in zones 4 to 9. In less humid climates, the vine is less vigorous and easier to control.
Fertilizer: Because trumpet vines are such aggressive spreaders and can thrive in lean soil, no supplemental fertilization is recommended.
