Care at a glance
Light
Most houseplants will scorch where scarlet banana thrives. Give it the windowsill you'd otherwise leave empty because everything else burned there. Best in full sun with at least 6 hours of direct light daily. Bright sunlight intensifies the red bract coloring. In partially shaded spots, growth continues but flowering is less prolific and bracts may be paler. A plant moved abruptly from low light to direct sun bleaches in 48 hours — always acclimatise over a week.
Watering
Aim for when the top 3-4 cm of soil is dry, roughly every 5-7 days for scarlet banana, but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Water regularly during the growing season, keeping the root zone consistently moist without waterlogging. The compact size means it dries out faster in containers than larger bananas — check soil moisture frequently in hot weather.
Soil and pot
Scarlet Banana grows best in rich, free-draining loam. Use a high-quality loam-based potting mix with added perlite (approximately 20%) for containers. In garden beds, incorporate plenty of compost. Good drainage is critical to prevent corm rot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.
Humidity and temperature
Scarlet Banana sits happiest at around 60-80% humidity and 18-35°C (65-95°F). Originating from humid subtropical forests, M. coccinea prefers high ambient humidity. Leaf edges brown quickly in dry air. Use a humidifier, pebble tray, or regular misting when grown indoors or in heated spaces. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.
Fertilising
Feed scarlet banana sparingly. Apply a balanced liquid fertiliser monthly during the growing season. Switch to a phosphorus-rich formula as flower spikes emerge to support the vivid bract development this species is known for. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.
Common problems
Below are the issues we see most often on scarlet banana in the Growli community. Each is annotated with the most common cause so you know where to start.
- Spider mites — Common in low-humidity indoor environments. Treat with insecticidal soap spray and improve ambient humidity to prevent reinfestation.
- Scale insects — Brown or white scales on pseudostems and leaf midribs. Scrape off manually and apply horticultural oil to eliminate remaining crawlers.
- Root rot — Overwatering or poorly draining containers cause corm rot. Always use free-draining compost and ensure pots have adequate drainage holes.
- Bract color fading — Insufficient light causes the characteristic scarlet color to fade to orange or dull red. Move to the brightest available position.
Companion plants
Scarlet Banana pairs well with Musa velutina, Heliconia orthotricha, Canna iridiflora, and Alpinia purpurata. These are species with similar light and water needs, so you can group them in the same room or on the same shelf and water as a batch.
Propagation
Propagate by detaching rooted suckers in spring. Suckers should be at least 30 cm tall and have their own root system before separation. Pot in rich, free-draining compost and maintain warmth above 20°C for fastest establishment. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.
Toxicity to pets
Scarlet Banana is pet-safe. Musa is listed by the ASPCA as non-toxic to dogs and cats. Musa coccinea is safe around pets; neither the ornamental bracts, inedible fruits, nor foliage contain compounds known to cause toxicity. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).
Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
Scarlet Banana care — frequently asked questions
What is the common name for Musa coccinea?
Musa coccinea is most commonly called Scarlet Banana, but it is also known as Scarlet Banana, Red-Flowered Banana, Crimson Banana. The names refer to the same species, so care instructions for Scarlet Banana apply identically to anything sold as Red-Flowered Banana.
How much light does scarlet banana need?
Scarlet Banana grows best in direct sun (at least 4-6 hours). Best in full sun with at least 6 hours of direct light daily. Bright sunlight intensifies the red bract coloring. In partially shaded spots, growth continues but flowering is less prolific and bracts may be paler.
How often should I water scarlet banana?
Water scarlet banana when the top 3-4 cm of soil is dry, roughly every 5-7 days. Water regularly during the growing season, keeping the root zone consistently moist without waterlogging. The compact size means it dries out faster in containers than larger bananas — check soil moisture frequently in hot weather. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.
Is scarlet banana toxic to cats and dogs?
Scarlet Banana is pet-safe. Musa is listed by the ASPCA as non-toxic to dogs and cats. Musa coccinea is safe around pets; neither the ornamental bracts, inedible fruits, nor foliage contain compounds known to cause toxicity.
What USDA hardiness zone does scarlet banana grow in?
Scarlet Banana is rated for USDA zone 9-12 and RHS hardiness H2. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
