“Abutilon ‘Cardinal’: The Scarlet Bell That Charms Through Three Seasons”
Abutilon hybridum ‘Cardinal’, commonly known as flowering maple or Chinese Lantern, is a striking ornamental shrub that brings vivid color and soft texture to gardens from early spring through fall. Despite its common name, this plant is not related to true maples. Instead, its name comes from the attractive, maple-shaped leaves that complement its profusion of hanging, bell-shaped red flowers. These long-lasting blooms dangle like miniature lanterns, drawing in hummingbirds and butterflies alike.
This cultivar belongs to the Malvaceae family, a group best known for showy, fast-growing flowering plants like hibiscus and hollyhocks. Native to subtropical regions and developed through hybridization, Abutilon hybridum ‘Cardinal’ offers a compact, upright form ideal for use in beds, borders, large containers, or even as a soft hedge in frost-free zones.
Gardeners love this plant not just for its beauty, but also for its versatility and long blooming season—from March through September or even later in mild climates. With moderate water needs, a tolerance for partial shade, and a tidy habit, it performs well with relatively little effort.
Description of Abutilon hybridum ‘Cardinal’
Abutilon hybridum ‘Cardinal’ is a fast-growing, semi-evergreen to evergreen shrub in warmer zones. It typically reaches between 90–150 cm (3–5 feet) tall and wide, forming a rounded, upright silhouette. Its leaves are soft green, lobed, and resemble maple foliage in shape and texture. The star attraction, however, is its flowers: rich, deep red bells that droop gracefully from the plant like delicate ornaments.
The combination of elegant foliage and long-lasting flowers makes this shrub stand out in both formal and informal landscapes. When in bloom, it serves as a beacon for pollinators, particularly hummingbirds, which are drawn to the vivid red coloring and abundant nectar.
How to Grow Abutilon hybridum ‘Cardinal’
Light
This plant thrives in bright conditions, doing best in full sun to partial shade. In particularly hot or arid climates, filtered afternoon shade is beneficial to prevent leaf scorch and help maintain vibrant foliage.
Soil
Abutilon hybridum ‘Cardinal’ prefers moist, well-drained soil with good fertility. It can tolerate a range of soil types, including loamy or sandy mixes, but performs best in slightly acidic to neutral soil (pH 6.0–7.0).
Watering
Moderate, consistent watering keeps this plant at its best. While somewhat drought-tolerant once established, it prefers evenly moist soil. Allow the top few centimeters (1–2 inches) of soil to dry out between waterings to avoid soggy roots or fungal issues.
Fertilizing
To encourage continuous bloom, apply a balanced, water-soluble fertilizer every two to three weeks during the active growing season (spring through fall). Use a formulation like 10-10-10 or 20-20-20 to promote healthy foliage and flower production. In early spring, mix organic compost or worm castings into the soil to give the plant a gentle nutrient boost.
Pruning
Abutilon hybridum ‘Cardinal’ benefits from regular pruning. Prune lightly throughout the growing season to shape the plant and encourage bushier growth. A harder cut-back in late winter or early spring can rejuvenate older plants and enhance flower production. Remove dead or spindly growth as needed.
Propagation of Abutilon hybridum ‘Cardinal’
Propagation is most effective through softwood or semi-hardwood cuttings taken in late spring or summer. Cuttings should be 10–15 cm (4–6 inches) long, with the lower leaves removed and the base dipped in rooting hormone. Place them in a moist, sterile growing medium under indirect light until roots develop. Keep humidity high for best results.
Seeds are also a possibility, although hybrid cultivars like ‘Cardinal’ may not come true from seed. For this reason, cuttings are preferred to maintain the specific traits of this vibrant cultivar.
Pests and Diseases
Abutilon hybridum ‘Cardinal’ is relatively pest-resistant but can be affected by common garden pests such as aphids, spider mites, and whiteflies, especially in warm or dry conditions. Neem oil or insecticidal soap can help manage infestations.
Fungal leaf spots and root rot may occur in poorly drained soil or with overwatering. Ensuring proper airflow around the plant and avoiding waterlogged conditions will help prevent these issues. In greenhouse or indoor environments, occasional problems with mealybugs may arise.
