Distinctive Features
Rubiginosa Alternanthera has small, oblong leaves that emerge with a red and bronze coloration, intensifying in color as the plant matures.

Growing Conditions
- Sun Exposure: Prefers full sun to partial shade. For the best foliage color, plant in an area that receives at least 4-6 hours of direct sunlight per day.
- Soil: Thrives in well-draining, fertile soil. It performs best in slightly acidic to neutral pH but is adaptable to a variety of soil types as long as they drain well.
- Water: Requires regular watering to keep the soil evenly moist, especially during dry periods. However, ensure the soil does not become waterlogged, as this can lead to root rot.
- Humidity: Prefers moderate humidity but can tolerate drier conditions once established, making it suitable for a range of climates.
- USDA Hardiness Zones: 9-11 (ideal for warmer climates but can be grown as an annual or houseplant in cooler regions).
Ideal Uses
- Container Planting: Its compact size makes it perfect for container gardens, adding vibrant color to patios, balconies, or small garden spaces.
- Flower Borders: Adds color and texture to flower borders, where its striking foliage creates a beautiful contrast against other plants.
- Edible Landscaping: While not typically grown for edible purposes, it can be used in edible landscapes as an attractive filler plant that complements herb and vegetable gardens.
- Mixed Plantings: Works well in mixed planting schemes, where its vibrant color can complement flowering plants or other foliage varieties.
Low Maintenance Care
Rubiginosa Alternanthera is relatively low-maintenance, requiring minimal care once established. It benefits from regular watering, occasional pruning, and light fertilizing to maintain healthy growth and vibrant color throughout the growing season.
- Watering: Water regularly to keep the soil evenly moist, but allow it to dry slightly between waterings to prevent root rot.
- Pruning: Prune back leggy or damaged growth to maintain a neat, compact appearance. Light pruning throughout the growing season will encourage bushier growth.
- Fertilizing: Apply a balanced, slow-release fertilizer in spring to support healthy growth. Avoid over-fertilizing, as the plant thrives in moderately fertile soil.
