The Stromanthe can be cultivated for indoor use, or it can be planted outdoors if you happen to live in a tropical climate. When grown outdoors, the leaves may achieve a three-foot spread with a stem height as tall as five feet.

The bright red stems of the Stromanthe plant can be quite alluring, especially when in contrast with its bright green foliage. If you are interested in smaller plants, you can pot them and raise them indoors, however for larger varieties they must be planted outside.

Moderate temperatures are best for this plant, specifically USDA hardiness zones 10 to 12. They should not be exposed to direct sunlight regardless of where they are planted, with partial shade being the most preferable. They love temperatures that range between room temperature and 70 degrees. If you are comfortable in a room, or under a specific tree, chances are this plant will love it as well. Anything lower than 60 degrees can cause leaf burn.

Watering The Stromanthe

Watering the Sanguinea is more complex than planting or even propagating the plant. It is unable to tolerate any amount of standing water. Soggy soil will quickly lead to root rot, but at the same time, it needs a lot of water to survive. The soil will need to remain moist but not soggy which makes selecting the right soil mix very important.

Certain types of this plant also need humidity in partnership with moist soil in order to grow well. For potted Stromanthe, it can be very difficult to ensure that it is getting the water it needs without becoming oversaturated. Choose a pot that has ample drainage holes in addition to placing it on a pebbled base. This will prevent water from standing in the pot and soaking the soil while also maintaining the right humidity level.

Ground planted Stromanthe are less prone to root rot since there is more soil to absorb any excess water. It is also important to fertilize your Stromanthe plant once every three weeks with a water-soluble liquid houseplant fertilizer that is properly balanced.

Taking care of your plant will reward you with a large indoor Triostar that reaches about three feet in height. If you are cultivating your plant outdoors, you can grow one as tall as a person.

These plants are Brazilian rain forest natives but with a bit of TLC and plenty of moisture, they can grow anywhere.

Propagating The Stromanthe

Propagating the Stromanthe Sanguinea is not very difficult, but it does take a bit of effort. You will need pots of well-draining soil for the cuttings. If you plan to leave your new plants in pots for indoor use, they will need to be shallow pots.

Ground bound Stromanthe Sanguinea can be planted directly in the soil, or in regular pots. Make sure to use a mix of perlite and houseplant potting mix to ensure that it drains properly. You can also substitute perlite with ground pumice if you will be planting your new cuttings in heavier soil.

The sanguinea can be propagated by cuttings or division. It is much easier to divide the plant than it is to create a healthy new plant from a cutting. For division, simply take a mature, healthy plant from its container or gently dig it up from the ground.

With a large plant knife, cut it at the base to create two separate root structures. If you are working with a particularly large Stromanthe, you can cut it into three or even four different root structures. Once you have separated each structure, place it in a new pot filled with your potting mix and perlite soil.

When taking cuttings for propagation, instead of taking from the stem it is better to take cuttings from the plant’s crown. Just like with division, plant each cutting in a small pot with the same perlite and potting soil mixture. It is a good idea to keep the plants inside until the roots have had time to develop.

Once they have taken root, you can transfer them into the ground or can place them in larger containers for indoor cultivation. Being tropical plants, they will need a lot of humidity in order to properly grow. Cover new plants with a plastic bag and keep them in a warm place until they are big enough to transfer to their permanent homes.
