About Joseph's coat
Amaranthus tricolor, commonly known as Tampala, is an annual herbaceous plant prized for its spectacular edible and ornamental foliage. Its leaves, often with vibrant combinations of red, yellow, and green, add an exotic and colorful touch to vegetable gardens and ornamental beds. It is ideal for borders or as a focal plant in large pots, where its colorful palette can be fully showcased.
Native range
Tropical and subtropical Asia, including India and Indonesia
Care tips
Tampala thrives in full sun, requiring at least 6 hours of direct light to develop its best coloration and growth. It needs regular and consistent watering, keeping the soil moist but not waterlogged, especially during warm periods. It prefers well-drained soil rich in organic matter; a good quality all-purpose potting mix with some compost is ideal. A common mistake is insufficient spacing, as it can grow quite large and needs good air circulation to prevent fungal diseases.
