Amaranthus hypochondriacus

The Story

Plant Bio

Amaranthus hypochondriacus is a vigorous, upright herbaceous annual distinguished by its stout, succulent stems and bold, colorful foliage. In summer and fall, it produces dense, rigid, catkin-like terminal spikes of deep purplish-red or crimson flowers that stand high above the leaves.

The simple, alternate leaves feature deep green, bronze, or purplish tints depending on the strain. This species serves as an excellent warm-season focal point or cut flower, adapting readily to lean, well-drained soils in full sun.

Uses & Benefits:

Ornamental UsesProduces striking, upright spikes of deep red flowers and colorful bronze or purple-tinted foliage.
Practical UsesYields high-quality cut flowers and edible seeds, and serves as a fast-growing temporary screen.
Ecological BenefitsProvides pollen for native bees and beneficial insects, and seeds for local seed-eating birds.

Planting

How to Grow

  1. Sow seeds directly outdoors after the last spring frost, or start indoors in plugs four to six weeks prior to planting out.
  2. Select a site in full sun with fertile, well-drained loamy, sandy, or clay soil.
  3. Space plants to support dense growth, which helps keep the tall, heavy flower spikes upright.
  4. Water regularly to establish the root system, then reduce watering to match its natural drought tolerance.

Pro Tip

Keep nitrogen fertilizer lean; excess nitrogen causes top-heavy stems to lodge and leads to a dangerous accumulation of nitrates in the foliage.

Care Guide

Do

  • Grow in full sun to ensure strong stems and vibrant foliage color.
  • Provide excellent soil drainage to prevent root and stem rot.
  • Handle young plugs carefully during transplanting to protect the taproot.

Don't

  • Do not over-fertilize with nitrogen, which weakens the stems and causes lodging.
  • Do not plant in waterlogged or poorly drained soils.
  • Do not prune the terminal flower spikes, as this is an annual grown specifically for its upright blooms.
