Stromanthe sanguinea 'Triostar' · Triostar Stromanthe (Tricolor Stromanthe)

The plant shows lance-shaped leaves with striking variegation in cream/white, green, and pink-magenta blotches and streaks, with leaf undersides and new growth showing deep pink-red coloration — classic features of Stromanthe sanguinea 'Triostar'. The growth habit (clumping, arching leaves from a basal rosette) and leaf texture also match this Marantaceae family member. Some leaf tip browning/curling is visible, consistent with the humidity-sensitive nature of this cultivar when grown outside ideal greenhouse conditions. Similar-looking alternatives to rule out would include other variegated Calathea/Goeppertia species or Ctenanthe cultivars, but the specific cream-pink-green tricolor pattern with pink leaf undersides is most characteristic of Triostar rather than typical Calathea patterns (which tend toward more symmetrical pinnate markings without this much pink). A clearer photo of the leaf underside (which should be solid deep magenta-pink in true Triostar) and any flower structure would help confirm with certainty.

Light

Bright, indirect light; avoid direct sun which fades the pink/white variegation and can scorch leaves. Too little light causes the striking coloration to revert to plain green.

Water

Keep soil evenly moist but not soggy; water when the top inch starts to dry out, typically weekly. Use filtered or distilled water if possible -- this plant is sensitive to chlorine, fluoride, and salt buildup, which cause leaf tip browning.

Nutrients

Dilute balanced liquid fertilizer every 4 weeks during spring and summer; skip in fall and winter.

Repotting

Repot every 1-2 years in spring, sizing up only slightly as it prefers being somewhat snug.

Soil media

Well-draining, peaty potting mix with added perlite and some orchid bark to hold moisture without staying waterlogged.

Temp & humidity

65-80F; high humidity (60%+) -- use a humidifier or pebble tray, as dry air causes crispy brown leaf edges.

Temperature range

🌡️ 65-80F

Humidity range

💦 60%+

Care group

🏷️ Bright & Humid

Toxicity

Non-toxic to pets and people -- safe near visitors and animals.

Pests & diseases

Watch for spider mites in dry conditions and root rot from overwatering or poor drainage; also prone to leaf tip browning from low humidity or hard water.

Propagation

Division at repotting -- separate rooted offsets/rhizome sections from the base of the plant and pot individually.
