Stromanthe Triostar has leaves streaked with cream, green and bright pink on top and deep magenta underneath. Like its prayer-plant cousins, the leaves lift at night. It's pet safe and gorgeous, and it needs steady moisture and humidity to stay that way.
Light + placement
Bright, indirect light brings out the pink. In lower light the leaves turn greener. Direct sun burns the pale variegated areas quickly.
Watering
Keep the soil lightly moist; water when the top 2β3 cm is dry. Don't let it dry out completely, and don't leave it soggy. Rested or filtered room-temperature water helps prevent brown tips.

Soil + repotting
Our Tropical Potting Mix. Repot every 1β2 years in spring. Large plants can be divided when repotting.
Feeding + upkeep
Feed monthly from April to September at half strength. Trim crispy edges and remove old yellow leaves at the base. Check under leaves for spider mites.
Common problems
| What you see | Likely cause | What to do |

| Pink fading to green | Low light | Move to brighter indirect light. |
| Yellow leaves, wet soil | Overwatering | Let the top few cm dry. |
| Fine webbing | Spider mites | Shower and treat with Houseplant Spray. |
