Growing in Pots, Balconies & Indoors

Amaranth is a fast, sun-loving annual ranging from 0.1 up to 2.5 m. The grower notes it is not an indoor houseplant, but it grows well in a pot on a sunny balcony or patio.

Quick Details

  • Container Size: 5-8 L (1.5-2 gal)
  • Indoor Suitability: Not a houseplant – it needs full sun
  • Best Spot: Full sun; it will grow in a little less but with fewer flowers
  • Soil & Drainage: Well-aerated, well-drained mix rich in organic matter – potting mix or peat with perlite or vermiculite
  • Watering in Pots: Average water; keep the soil moist

Indoors & On the Windowsill

  • Houseplant limits: The grower marks it as not for indoors – it is a sun-hungry annual that grows leggy in weak light.
  • Windowsill note: Only the very sunniest sill could hold a young pot, and it is far happier outside.

On a Balcony or Patio

  • Light & wind: Give it the sunniest spot; tall types may need staking on an exposed balcony. Pots against warm walls dry fast – check moisture regularly and a mulch helps cut evaporation.

Choosing the Pot, Soil & Long-Term Care

  • Pot & drainage: A pot with strong drainage holes is essential; skip a permanently full standing-water saucer to avoid root rot. Terracotta breathes and dries faster, while glazed or plastic holds moisture longer.
  • Potting mix: Well-aerated and organic-rich – potting mix or peat with perlite or vermiculite; a mulch keeps it moist.
  • Feeding: Potted plants need feeding more often than those in the ground, since watering steadily leaches nutrients out of the container.

Bloom & Flower Guide

Quick Details

  • Bloom Season: Summer into autumn
  • Time to First Bloom: In its single season — this annual flowers from mid to late summer
  • Flower Appearance: Many tiny flowers packed into bold, often drooping tassel-like plumes in purple, yellow, white, red, green or orange
  • Edibility: The plant is grown for its edible leaves and grain (both covered elsewhere); the flower plumes themselves are ornamental rather than a flower you eat

Detailed Blooming Overview

Amaranthus is one of the most dramatic flowering annuals you can grow, sending up thick, tassel-like plumes of countless tiny flowers that may stand erect or spill down in long ropes. The plumes hold their colour for a very long time and are superb both in the garden and dried. The flowers later give way to nutritious seed, which is why growers often leave the plumes to mature rather than removing them.

Flower Characteristics

  • Individual flowers are minute, but they are massed into large, showy plumes.
  • Colours span purple, yellow, white, red, green and orange.
  • The plumes are long-lasting and dry well for arrangements.

Bloom Care & Thinning

  • Deadheading: Not usually recommended — the flower plumes ripen into edible grain, so most growers leave them to mature.
  • Pollination: Amaranth is mainly wind-pollinated (its tiny flowers do not depend on bees), so it sets seed freely on its own.
  • Support: The heavy plumes can weigh tall stems down; a stake keeps top-heavy plants upright while they flower.
