Play with the Autumn Palette

Here’s an autumn pairing to inspire daydreams of your summer snorkeling adventures; don’t you think the amaranth looks like underwater coral? And the hyacinth bean petals are like shimmering scales of swimming fish! Majestic scarlet plumes dominate this combo, but dainty dancing lavender-and-pink flowers add sparkle. After the flowers come eye-catching royal purple bean pods. For an additional pop of color, the amaranth foliage changes to deeper red in fall, glowing orange when it catches the light.

Growing tips

  • Give the hyacinth bean a trellis to climb and these tall plants become bosses in the back of the border.
  • When the purple bean pods mature and dry, harvest the seeds inside. You can plant them again in spring, but soak them overnight before planting.
  • The amaranth may need staking, especially if it’s in a windy location.
  • Direct sow amaranth seeds in spring and thin to 18 to 24 inches apart.
  • The amaranth doesn’t need much water, and poor soil means stronger foliage color.
  • Amaranth seeds can be harvested, cooked and eaten; they’re very similar to quinoa. If you don’t like them, the birds will!
