Stromanthe Triostar is an eye-catching exotic perfect for the intermediate grower. This moderately fast grower has leaves splashed with green, white, and pink for a fun and unusual look. Stromanthe sanguinea is in the Prayer Plant family and will close its leaves at night when temperatures are cooler. This plant is native to the Amazon jungle in South America.

Best Locations For Growing Stromanthe Triostar

A bathroom window that faces east or west is perfect for Triostar. The high humidity and indirect light help keep the foliage color vibrant. Triostar does not like large fluctuations in room temperature and will fold its leaves up toward the center of the plant when it is too cold. Consistent temperatures between 70-85 degrees F are ideal. Stromanthe is not considered toxic and can be safely grown near children and pets.

Stromanthe Triostar Sunlight Requirements

Bright indirect light or filtered light indoors is where Stromanthe thrives. The fabulous leaf coloring bleaches in stronger light and fades to mostly green in low light levels. Place Stromanthe in a west- or east-facing window.  

Stromanthe Triostar Care

Stromanthe appreciates potting soil with good drainage. Using a mix of soil-based potting mix and perlite will meet these needs. Pruning is rarely needed, although regular grooming of dead or dying leaves will help deter pest and disease infestation. The best time to repot Triostar is in the spring as new growth is beginning. This moderately-growing plant should be given new soil every 2-3 years after reaching its mature size.

Watering Stromanthe Triostar

Consistently moist soil is not easy to achieve year-round. Triostar likes the soil to feel like a wrung-out sponge. The top 1-2 inches of soil should be left to dry out in between watering. Use either distilled water or tap water left to sit for 24 hours, letting the chlorine dissipate. Humidity is best kept high with a daily light misting of water. Use distilled water, which will not leave white salt marks on the glossy leaves.

Feeding Stromanthe Triostar

Fertilize Stromanthe only during the active growth period in spring and summer. A balanced houseplant food supports foliage growth and color as well as strong root development. Look for a fertilizer that has an NPK ratio of 10-10-10.
