Growing in Pots, Balconies & Indoors

Alternanthera are tender, brightly coloured foliage plants that grow well in containers. The grower does not class them as true houseplants – they need strong light to keep their colour – but a bright, sunny windowsill suits them, and growing in a pot lets you shelter a tender plant under cover before frost.

Quick Details

  • Container Size: 10-30 L (2-6 gal), sized to annual or perennial use
  • Indoor Suitability: Not a true houseplant, but happy on a bright, sunny sill
  • Best Spot: Full sun to part shade – brighter light means richer colour
  • Soil & Drainage: Aerated, organic-rich mix with good drainage (potting mix or peat with perlite/vermiculite)
  • Watering in Pots: Keep evenly moist – average to generous water, never bone dry

Indoors & On the Windowsill

  • Houseplant limits: The grower does not rate them as indoor plants; in dim light the leaves fade and the stems stretch.
  • Windowsill growing: A bright, sunny sill keeps them compact and colourful – turn the pot now and then for even growth.
  • Overwintering: In cold climates, move a potted plant to a bright, frost-free spot indoors for winter, then return it outside once it warms.

On a Balcony or Patio

  • Light & wind: Give it the sunniest spot you have. Walls, railings and paving reflect heat and dry pots quickly, so check moisture daily in warm weather and shelter or stake exposed plants against wind.
  • Practicalities: Check that the filled pot’s weight is safe for the balcony and that drainage runoff can escape freely without pooling on the floor below.

Choosing the Pot, Soil & Long-Term Care

  • Pot & drainage: Use a container of at least 10-30 L (2-6 gal), sized to whether you grow it as an annual or a longer-lived perennial. Make plenty of holes so water runs out freely – the soil should stay moist but never waterlogged.
  • Potting mix: A well-ventilated mix with good drainage, rich in organic matter – a general potting mix, or peat soil with perlite or vermiculite.
  • Keeping it moist: Lay a mulch over the surface to hold moisture, as pots dry faster than open ground.
  • Feeding: Feed at least once a year with an organic-rich fertilizer; potted plants use up and leach nutrients faster than those in the ground.
  • Repotting (as a perennial): Every few years, refresh the soil and prune back part of the roots and the top growth to keep it vigorous.

Bloom & Flower Guide

Quick Details

  • Bloom Season: Spring and summer
  • Time to First Bloom: Grown mainly for foliage; flowers appear on established plants in the warm season
  • Flower Appearance: Small pompon-shaped flower heads in white, green, yellow or purple
  • Edibility: The flowers are ornamental and not eaten (in some species the leaves are edible)

Detailed Blooming Overview

Joyweed is grown as a colourful ground cover, valued for its foliage. In spring and summer it produces small pompon flowers – tiny blooms joined at the base into rounded heads – in white, green, yellow or purple. They are a quiet feature compared with the leaves.

Flower Characteristics

  • Small flowers joined at the base into rounded, pompon-like heads.
  • Colours range through white, green, yellow and purple; nectar is worked by bees.

Bloom Care & Thinning

  • Managing the bloom: Trim to keep the ground cover dense; the flowers need no special care.
  • Pollination: Carried out by bees.
