Growth Stages

1

Seedling

1-2 weeks

Tiny plants with first true leaves emerging; delicate with light green coloring

Keep soil warm (70-75°F) and consistently moist; provide bright indirect light; avoid overwatering

2

Vegetative Growth

3-4 weeks

Plants develop bushy habit with multiple stems; maroon coloring begins to intensify

Pinch growing tips to encourage bushiness; feed weekly with balanced liquid fertilizer; maintain warm conditions

3

Established Plant

4-8 weeks

Full bushy form with deep burgundy foliage; develops small cream-colored flower spikes

Continue pinching for desired shape; maintain consistent moisture and warmth; deadhead flowers if foliage display is priority

4

Flowering

Ongoing in warm conditions

Small elongated white or cream flower spikes appear among the foliage

Flowers are less showy than foliage; remove for better plant shape if desired; continue regular fertilizing

5

Decline (Cool Season)

Variable with climate

Growth slows in fall/winter; leaves may fade; plant becomes less vigorous

Reduce watering and fertilizing; move to warmer location if possible; in frost zones, bring indoors or treat as annual

Uses

🍳

Edible ornamental

Culinary

Leaves are technically edible and have a mild, slightly bitter flavor. Some cultures use Alternanthera species in salads and cooked dishes, though Maroon Beauty is primarily grown for ornamental purposes. [source]

🏠

Container and bedding displays

Household

Maroon Beauty excels in mixed containers, hanging baskets, borders, and massed plantings where its dark foliage provides striking contrast to bright flowers or light-colored plants. [source]

🎨

Floral arrangements and design

Craft

The deep maroon leaves are excellent filler material in fresh or dried floral arrangements, adding depth and color contrast to bouquets and landscape designs. [source]

🏠

Indoor houseplant

Household

Maroon Beauty grows well as a houseplant indoors on bright windowsills or under grow lights, adding tropical color to homes during winter months when outdoor growing is impossible. [source]

🦋

Pollinator habitat

Wildlife

The small flowers attract beneficial insects including butterflies, hoverflies, and bees, supporting pollinator populations in gardens and containers. [source]

Harvest Tips

This is a foliage plant, not harvested for produce. Pinch off growing tips regularly starting when plants are 4-6 inches tall to encourage bushiness. Remove flower spikes if foliage display is the priority. Cuttings can be propagated in water or moist soil year-round for new plants.

Fun Facts

  • 🌱 Maroon Beauty is not winter-hardy in most of North America and must be treated as a tender annual or brought indoors; gardeners often overwinter cuttings or mature plants to replant the following spring
  • 🌱 The intensity of the maroon-burgundy color deepens with more sunlight exposure—plants grown in partial shade will be greener, while full-sun plants develop the rich, deep maroon coloring for which the variety is named
  • 🌱 Alternanthera species are used in aquascaping and aquarium environments as attractive aquatic plants, though terrestrial Maroon Beauty should not be permanently submerged
