Description
Amaranthus tricolor Joseph's Coat, also known as Joseph's Coat amaranth, is a tall, fast-growing annual plant, cultivated for its variegated young foliage with great ornamental value. Its juvenile undulate leaves, gathered in clusters, blend bronze, gold, orange, and red in large splashes that persist well into autumn. This plant is magnificent in flower beds, pots, or bouquets. It thrives in sunlight, well-drained soil rich in nitrogen.
Also known as tricolor amaranth or elephant-head amaranth, this bushy annual belongs to the Amaranth family. It is native to tropical areas of Southeast Asia (China, Japan, India, Java). It forms vigorous clumps, 60 cm (24in) in height and 40 cm (16in) in diameter throughout the year. 'Joseph's Coat' is a cultivar with richly coloured foliage. The large evergreen leaves are elongated and tapered, wavy-edged, and strongly veined. They are alternate and arranged in a circle around the thick, sturdy stems. When juvenile, at the tips of the stems, they are flamboyant, variegated, and their beautiful colours persist until the first frost. Then they turn green. The flowering, quite inconspicuous in this variety, occurs in late summer and autumn. The tiny red flowers are gathered in modest panicles.
Amaranthus Tricolor are wonderful foliage plants that have their place in flower beds. Their exotic appearance also suits large pots on the patio. They are also edible plants, which can be sown in the vegetable garden. They can be consumed raw in salads or cooked like spinach.

Planting and care
Sow Amanthus tricolor seeds in early spring at 21-24°C (69.8-75.2°F) in good potting compost. Bury the seeds 2mm (0.1in) deep and keep the soil moist but not waterlogged. It can be beneficial to enclose the sowing in a polythene bag. Germination usually takes 10 to 14 days. When the plants are large enough to handle, transplant them into pots or boxes and acclimatise them to cooler conditions. Then gradually acclimatise them to outdoor conditions for 10 to 15 days before planting them when the frosts have passed, spacing them 30-40cm (12-16in) apart in a sunny location, in good, deep garden soil. These plants are quite water-demanding.
Amanthus tricolor have a taproot system. It is best to avoid moving them when they are too large.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
