Stromanthe sanguinea care
Stromanthe sanguinea is a member of the prayer plant family and shares many characteristics with its ‘cousins’, such as the equally beautiful rose painted prayer plant.
The species is naturally found in Brazilian rainforests, which gives us some care indications: due to light being blocked by large trees, rainforest plants don’t appreciate direct sun.
These plants need high humidity to thrive and the average home might be a little too dry for them.
Stromanthe sanguinea light, location & temperature
Because Stromanthe sanguinea will burn when exposed to too much direct sunlight but still appreciates a relatively bright environment, it’s a good idea to avoid any windows that receive bright afternoon sun and go for something like a North-facing window instead.
If you’re worried about sun exposure, place a sheer curtain between the window and the plant.
Humidity is one of the biggest challenges when growing Stromanthe sanguinea. Try to find a location for it that’s as humid as possible: most homes are simply too dry.
The bathroom or kitchen might be a good choice. If you’re running a humidifier for your plants, this is definitely a contestant for a spot near it. A humidity tray is another option.
Because Stromanthe sanguinea is a tropical plant it does not appreciate low temperatures, so you’ll have to keep it away from cold at all times.
Normal room temperature works just fine. If your home doesn’t get too chilly during the cold months the plant should do just fine.
Planting Stromanthe sanguinea
Because Stromanthe sanguinea likes a humid environment and should be kept moist, some special care should be taken when planting it. This plant is a great option for terrariums and other (partially) closed environments that trap moisture for a longer time.
Be sure to always keep an eye out for rot, though. Your Stromanthe’s soil should be moist, not wet.
Plant your Stromanthe sanguinea in a pot with a drainage hole to prevent standing water from causing root rot. Due to its rhizomatous nature, this plant does well in shallow planters or bowls. When it comes to soil, a peat-based medium is often recommended.
Because peat isn’t the most renewable resource, try creating an alternative by mixing your own soil. A combination of water-retaining coco coir, potting soil and drainage-increasing perlite should work well.
Watering Stromanthe sanguinea
When figuring out the proper watering schedule for your Stromanthe sanguinea, it’s very important to keep in mind that this plant likes its soil moist but never wet for longer periods of time. To prevent the soil from becoming either too wet or to dry, try watering once the top inch (2-3 cm) or so has dried.
There are a few things you can do to keep the moisture level around the plant high enough. The best option is to place it near a humidifier, a bit of an investment but definitely worth considering if you grow many tropical plants in your home.
You can also try regularly misting the plant, placing it near other plants or using a humidity tray.
Feeding Stromanthe sanguinea
You can fertilize Stromanthe sanguinea during the growing season as long as it’s producing new leaves.
A regular houseplant fertilizer can be used, though be sure to dilute it to half strength.
Buying Stromanthe sanguinea
Stromanthe sanguinea is a member of the prayer plant family but a bit less easy to find than some of its cousins, though you might be able to locate one in larger garden centers and plant stores.
You can also easily buy Stromanthe sanguinea online.
Is Stromanthe sanguinea toxic to cats and dogs?
Although the ASPCA doesn’t have specific information about this species, it lists Calathea, its close relative, as safe.
Other sources also report that although ingestion of any plant can cause an upset stomach in your pet, Stromanthe sanguinea is not toxic and shouldn’t cause any further problems.
