The Two Primary Varieties of Malabar Spinach
While Malabar spinach (Basella species) goes by several names, including vine spinach and Ceylon spinach, it is broadly categorized into two main types based on its stem and leaf color. Both are edible, but their appearance and best uses can vary slightly. These two types are Green Malabar Spinach (Basella alba) and Red Malabar Spinach (Basella rubra or Basella alba 'Rubra'). A keen gardener can identify the differences instantly by looking at the color of the vines and the leaves' pigmentation.
Green Malabar Spinach (Basella alba)
Green Malabar spinach is the variety most commonly cultivated for its culinary applications. This fast-growing, perennial vine features thick, fleshy, dark green, heart-shaped leaves on solid green stems. It has a milder flavor compared to its red counterpart and retains its color well when cooked, making it a reliable substitute for true spinach in stir-fries, soups, and curries. Its vigorous growth habit makes it a productive addition to any warm-weather garden.
Red Malabar Spinach (Basella rubra)
Red Malabar spinach is celebrated for its striking visual appeal, making it a popular choice for edible landscaping. It is characterized by vibrant reddish-purple stems, which provide a beautiful contrast against its deep green, often pink-veined leaves. The leaves on the red variety tend to be more rounded than the heart-shaped leaves of the green type. When cooked, the red pigment from the stems can leach out, which is why it is often preferred raw in salads to preserve its ornamental appearance. The red variety is also known for producing purple-black berries that can be used as a natural dye.
Other Notable Cultivars
Beyond the two main color variations, there are specific named cultivars that have been developed for certain traits:
- 'Bangladesh': A vigorous, heat-tolerant variety with large leaves, known for producing thick vines that can be grown on trellises or as a groundcover.
- 'AVRDC': A cultivar with smaller leaves than the 'Bangladesh' variety, but also very vigorous. It is a productive choice for those seeking a quick harvest.
Growing the Different Types of Malabar Spinach
Regardless of the type, Malabar spinach cultivation follows similar guidelines, favoring tropical and subtropical climates where it can thrive in heat and humidity. All varieties are frost-sensitive and are typically grown as annuals in cooler regions.
Key Growing Requirements:
- Sunlight: Full sun is preferred for best growth, but the vines will tolerate partial shade, which may result in larger, more succulent leaves.
- Soil: A rich, well-draining soil with high organic matter is ideal. The plant is adaptable but appreciates consistent moisture.
- Support: All types of Malabar spinach are climbing vines and require a sturdy trellis, fence, or other structure to grow vertically. This maximizes airflow and minimizes fungal diseases.
- Watering: Consistent and regular watering is crucial, especially in high heat. Insufficient water can trigger premature flowering and lead to bitter-tasting leaves.
- Harvesting: Regularly harvesting the young, tender leaves and vine tips encourages new growth throughout the season.
Comparison of Malabar Spinach Varieties
| Feature | Green Malabar Spinach (Basella alba) | Red Malabar Spinach (Basella rubra) |
|---|---|---|
| Stem Color | Green | Reddish-purple to maroon |
| Leaf Color/Veins | Uniform dark green leaves | Deep green leaves with prominent pink or reddish veins |
| Leaf Shape | Typically oval to heart-shaped | Often more rounded and thick |
| Best Culinary Use | Cooked, as a spinach substitute in soups, curries, and stir-fries | Raw, in salads, to preserve vibrant color |
| Flavor Profile | Mild and similar to true spinach | Slightly different, sometimes noted for an earthy flavor |
| Ornamental Value | Moderate, used primarily as a food crop | High, used widely in edible landscaping |
| Fruit | White flowers producing berries that ripen to a purplish-black | Pink flowers producing berries that ripen to a dark purple |
Culinary and Ornamental Applications
Malabar spinach's versatility extends beyond just the garden. The red variety's colorful stems and vines are excellent for creating ornamental screens, decorating arbors, or cascading from hanging baskets. Its ability to tolerate heat also makes it a valuable asset for summer plantings when many other leafy greens struggle. In the kitchen, the mucilaginous quality of the leaves acts as a natural thickener, especially useful in stews and sauces. For gardeners looking to grow both a productive vegetable and an attractive plant, a mix of both green and red varieties offers the best of both worlds.

Conclusion
Ultimately, the choice between the different types of Malabar spinach depends on your specific goals. If your priority is a high-yielding, all-purpose leafy green for cooking, the green Basella alba is the most practical choice. If visual appeal is a major factor for your garden design or if you prefer to consume your greens raw in salads, the red Basella rubra is an outstanding option. Both varieties provide a nutritious and reliable harvest throughout the hottest months, offering a fantastic summer alternative to regular spinach. By understanding these distinctions, gardeners can make an informed decision and enjoy this unique and prolific climbing vegetable.
What are the different types of Malabar spinach?
