Establishment
2-4 weeksYoung plant with small, developing leaves featuring the characteristic pink pinstripes on dark green foliage. Plant is acclimating to its environment.
Maintain high humidity (60-80%), avoid moving frequently, water gently to prevent transplant shock, keep in warm conditions (65-75°F).
Vegetative Growth
3-6 monthsPlant develops multiple new leaves and increases in size. Pinstripe patterns become more vibrant and pronounced as mature leaves emerge.
Maintain bright indirect light, increase humidity with misting or pebble tray, feed with diluted balanced fertilizer every 3-4 weeks, rotate plant weekly for even growth.
Mature Growth
OngoingPlant reaches full size with lush foliage displaying full intensity of pink or white stripes. May produce flower spikes with delicate pink or purple blooms.
Continue consistent moisture and high humidity, prune dead or yellowing lower leaves, fertilize monthly during growing season, repot every 18-24 months.
Blooming
2-3 weeks per bloom cyclePlant produces slender flower spikes with small pink or mauve flowers. Blooming may occur intermittently throughout the year indoors.
Maintain all regular care practices, do not remove flower spikes prematurely, blooms last 2-3 weeks, fertilize to support flowering energy.
Dormancy
2-3 monthsPlant growth slows during winter months. Leaf movement (nyctinasty) becomes more pronounced as plant folds leaves at night.
Reduce watering slightly but maintain consistent moisture, lower fertilizing frequency to once per month or stop entirely, maintain warmth (minimum 60°F), continue providing bright light.

Fun Facts
- 🌱 Calathea Ornata's leaves exhibit nyctinasty—they fold upward at night and unfold during the day, a behavior called 'prayer plant movement' that you can hear as an audible rustling sound.
- 🌱 The pink or white stripes on the leaves are produced through selective pigmentation in leaf cells; younger plants may have less vibrant stripes that intensify as the plant matures in optimal light conditions.
- 🌱 In its native South American rainforest habitat, Calathea Ornata grows as an understory plant, which is why it thrives in indirect light rather than direct sun exposure.
