What Is Amaranthus Caudatus?

Appearance

• The light-green foliage of amaranthus caudatus provides the perfect backdrop for its striking reddish-purple or gold flowers. The plant itself can grow up to 5 feet tall and boasts drooping blooms in summer. A healthy specimen may grow up to 30 inches in diameter. The blooms last until the first frost of fall and sometimes grow long enough to brush the ground.

Growing Requirements

• Amaranthus caudatus is not a demanding plant. It puts on a colorful show as long as it receives exposure to part sun each day and actually performs best in poor soil. It prefers dry soil and handles drought conditions very well. Avoid planting in slow-draining, soggy soil, as this is practically the only condition this flower can't handle. To prolong the blooming season, start amaranthus caudatus indoors about six weeks before the last frost in spring.

Maintenance and Problems

• Watering is only necessary during the first few weeks after planting and during very dry conditions. Foliage is improved by a monthly dose of water-soluble, all-purpose fertilizer throughout the growing season. Pests and disease are generally not a concern, though aphids do occasionally set up camp on amaranthus caudatus. A blast from the garden hose usually takes care of the problem. Root rot can be an issue, but only in sites with less than ideal drainage.

Uses

• Amaranthus caudatus can be used in many ways. It makes an ideal patio plant, especially when added to a hanging basket, where its flowers droop downward dramatically. It makes a bold specimen planting and can also be mixed into flower beds. Amaranthus caudatus can even be grown as a small shrub. The blooms make attractive cut flowers and also hold their color well when dried.
