Cardinal climber, botanically known as Ipomoea × multifida (often sold as Ipomoea sloteri), is a fast-growing annual vine valued for its delicate foliage and bright tubular flowers. It develops slender, twining stems with finely divided, fern-like leaves and produces vivid red, star-shaped blooms throughout the growing season. This plant thrives in warm climates and performs best in full sun with well-drained soil. Cardinal climber is commonly used on trellises, fences, and arbors, where it establishes easily from seeds and grows rapidly under suitable conditions.
