Amaranthus tricolor. Thomas Jefferson included the Joseph's Coat, or "three-coloured Amaranth", in a shipment of seeds from Paris to his brother-in-law, Francis Eppes, in 1786. The vibrant yellow and red foliage of this brightly plumed tender annual provides an eye-catching display of color. Its edible leaves have a walnut-like flavor and can be eaten raw in salads or steamed. Joseph's Coat grows to four to five feet and likes a warm, sunny location. Vibrant colors will not begin to appear until plants near and start flowering. ~1/4-1/2tsp per packet.
