Ipomoea sloteri—often called Ipomoea × multifida, and commonly called both Cardinal Climber, and Cypress vine—is an annual flowering vine that's known for its small, bright red flowers that hummingbirds absolutely love.
Although it's commonly referred to as Cypress Vine, Cardinal Climber is actually a cross between Cypress Vine (Ipomoea quamoclit) and Morning Glory Vine (Ipomoea coccinea), which it's also sometimes called.
It's easy to see the result of the cross of the two species when looking at their respective foliage. The leaves of Cardinal Climber are a combination of the needle-like leaves of Ipomoea quamoclit, and the full heart-shaped leaves of Ipomoea coccinea.
Cardinal Climber is a fast grower, especially in hot weather! Expect at least 10' of growth, with some growing over 15' tall.
It's great at climbing all types of things such as trellises, houses, fences, and trees.
Ipomoea sloteri will form seeds in early fall, which can be harvested for planting next year.
Cardinal Climber Care
Ipomoea × multifida is typically grown as an outdoor plant, although it's sometimes grown as an indoor annual or a patio plant.
Cardinal Climber loves full sun, and also thrives in partial shade.
Fertilize as required, especially if planted in poor soil. It's best to fertilize Cardinal Climber with 1/2 strength fertilizer, as it's a light feeder. Our slow release plant food or something similiar is a good option.
Keep its soil moist, but not wet. Irrigate during establishment, and during periods of drought.
Does best and grows fastest in humid conditions when the temperatures are above 80°F. Do not plant when soil temperatures are below 55°F.
This is not a frost tolerant plant.
