Calathea roseopicta 'Black Rose' is one of the darkest of the rose painted calatheas. The leaf surface is so deep a green it reads almost black, lit by a vivid pink midrib and feathered pink markings, with the rich purple undersides typical of the species. New leaves open with the strongest pink and darken as they mature, and the whole plant folds its foliage upward at night like every good prayer plant.
Origins. The species, now filed by botanists as Goeppertia roseopicta, comes from the rainforest floor of northwest Brazil, where it grows in warm, humid shade. 'Black Rose' is a modern selection of it, sold in the trade under this name and matching the cultivar recorded as 'Dottie'. Like all calatheas it is non-toxic to cats and dogs, so it belongs with our pet safe houseplants.
Care. Give it bright, indirect light to light shade; direct sun bleaches the dark colour. Keep the compost evenly moist with rainwater or filtered water, never soggy, and aim for 60 per cent humidity or more, as with the rest of our humidity loving houseplants. Keep it warm, above 15C, and it will reward you as one of the most striking houseplants you can grow for a shadier spot.

Calathea roseopicta 'Black Rose' is a houseplant that takes a little effort. It needs bright indirect light, watering often enough to keep the compost evenly moist, high humidity and a minimum temperature of 15°C. It is listed as non-toxic to cats and dogs.
A little effort
Bright, indirect light
Bright, indirect light or light shade. Direct sun fades the near black colour and pink markings; deep gloom slows growth.
Keep evenly moist
Keep the compost evenly moist, watering when the surface starts to dry. Rainwater or filtered water keeps the leaf tips clean; never let it stand in water.
Needs high humidity
Happiest at 60 per cent humidity or more. Group plants together or use a humidifier; crisp edges mean the air is too dry.
Keep above 15°C · Likes a warm room
Warm and steady, ideally 18 to 24C and never below about 15C. Keep it clear of cold draughts, open windows and radiators.
Feed monthly with a balanced fertiliser from spring to autumn, and let it rest over winter.
Listed as non-toxic to cats and dogs. Plants still are not food, so a determined chewer may get an upset stomach.
Calathea roseopicta 'Black Rose'
They are at least siblings and very likely the same plant. Singapore's NParks flora database records 'Dottie' as the correct cultivar name for plants sold under the Black Rose trade name. Some growers list them separately, with Black Rose described as the darker of the two, but no botanical source separates them. We sell it under the name it arrives with from the nursery.
Both. The species was long known as Calathea roseopicta, and botanists moved it with most other calatheas into the genus Goeppertia, so the current botanical name is Goeppertia roseopicta. Growers and shops still use Calathea, which is why we do too.
Yes. Calatheas are in the prayer plant family, Marantaceae, which the ASPCA lists as non-toxic to cats and dogs, so it is a good pick for homes with pets.
Two usual causes. Older leaves naturally darken as the pink zones mature to deep green, which is normal for roseopicta cultivars. If the whole plant is paling or bleaching, it is getting too much direct sun; move it to bright, indirect light.
Dry air, hard tap water or irregular watering. Keep the compost evenly moist, push humidity towards 60 per cent or more, and switch to rainwater or filtered water, since the minerals in hard tap water scorch calathea leaf margins.
Yes. This plant is listed as non-toxic to cats and dogs, so it's a good choice for homes with pets. Even so, plants aren't food, so a keen chewer could still get an upset stomach. If you're worried, speak to your vet.
