Roseleaf Morning Glory | Features and Care

The Roseleaf Morning Glory is a tropical climbing plant characterized by its vivid magenta flowers and distinct five-lobed glossy leaves. Though rarely seen in Japan, it is cultivated as an ornamental plant in gardens and greenhouses throughout tropical and subtropical regions.

This article explores its morphology, cultural and historical background, and practical tips for growing.

Basic Information

• Scientific name: Ipomoea horsfalliae
• Family: Convolvulaceae
• Origin: West Indies (especially Jamaica and Trinidad)
• Appearance:
  This is an evergreen perennial climber with palmately lobed, dark green glossy leaves. The flowers are funnel-shaped, about 5–7 cm in diameter, with a bright magenta or purplish-red color. They bloom in clusters along the vining stems, which grow vigorously and cover trellises or fences.
• Blooming Season:
  In tropical regions, it can bloom year-round. In temperate areas, it typically blooms from late summer to winter. Depending on light and temperature conditions, it may flower multiple times a year.

Cultural Significance Around the World

The Roseleaf Morning Glory is widely cultivated in tropical climates as a decorative plant, especially in tropical gardens and greenhouses. In the Caribbean, it is commonly used to line pathways or property boundaries. The unique shape of its five-lobed leaves adds visual interest, making it popular for growing along trellises and fences.

In Western countries, especially since the Victorian era, it has been featured in greenhouse horticulture. It has been included in plant collections at major institutions like the Royal Botanic Gardens, Kew (UK) and the Jardin des Plantes (France). In Japan, though not commonly seen, it is valued among plant enthusiasts and occasionally featured in botanical exhibitions.

Historical Background

Ipomoea horsfalliae was named in honor of the wife of 19th-century British businessman and plant collector Charles Horsfall. He actively collected tropical plants in the West Indies and cultivated a wide variety in his personal garden. This species was among those he grew, and the name “horsfalliae” was chosen to pay tribute to his wife. Such dedications were a common practice in 19th-century horticulture, reflecting respect and recognition among individuals involved in the field.

The plant was later introduced into royal gardens and botanical institutions. By the late 19th century, it had earned recognition as a valuable ornamental vine. Today, it continues to hold academic and horticultural significance, often featured in herbarium collections and educational exhibits.

Gardening Advice

The Roseleaf Morning Glory thrives in warm climates. In Japan and other temperate regions, it is best grown in containers. Below are the key care points:

Sunlight

Requires ample sunlight—at least 5 hours of direct light daily. Insufficient light may reduce flowering.

Watering

Water thoroughly when the surface soil dries. During hot weather, monitor closely to avoid dehydration. Reduce watering in winter.

Soil

Prefers well-draining soil. Use commercial potting mix with added perlite or pumice. Slightly acidic to neutral pH is ideal.

Fertilizer

During the growing season (May–September), apply liquid fertilizer every two weeks. Fertilizers with phosphorus promote flowering.

Pruning and Training

Prune overgrown vines and guide growth with supports. Pruning encourages branching and more blooms.

Overwintering

Not frost-tolerant. Keep above 10°C. Move indoors during winter and use supplemental heating if necessary.

Conclusion

Ipomoea horsfalliae, commonly known as the Roseleaf Morning Glory, is a tropical vine with vivid flowers and deeply lobed leaves.

It originated in the West Indies and was introduced to Britain in the 19th century by plant collector Charles Horsfall, who cultivated it in his garden. The plant’s name honors his wife. Over time, it became established in royal and botanical gardens, where it is still appreciated today.

With suitable care, it offers a unique visual appeal and remains a valuable species in horticultural collections.
