Seedling
6-12 monthsTiny plantlets with 2-3 small leaves and developing root system; extremely delicate and slow-growing
Maintain high humidity (70-80%); use fine-grade orchid bark or sphagnum; provide bright, indirect light; avoid direct water spray; be patient—growth is very slow
Juvenile vegetative
12-24 monthsPlant develops multiple thin, wiry leaves and small root system; gradually increases in size but remains compact
Continue high humidity and bright light; water when media is nearly dry; provide good air movement; repot only when plant significantly outgrows current media (every 18-24 months)
Mature vegetative
OngoingPlant reaches full foliage, producing multiple thin stems or inflorescences; compact growth habit; ready for flowering
Maintain consistent warmth (65-75°F nighttime minimum); ensure bright light and humidity; slight drying between waterings can encourage blooming; well-established plants may produce flowers multiple times yearly
Blooming
3-6 weeks per bloom cycle; may rebloom multiple times per yearSlender, branching flower spikes emerge with numerous small white or pale pink fragrant flowers; petals and sepals are thin and delicate; flowers last 3-6 weeks per spike
Continue regular watering and humidity; provide good air circulation to prevent fungal issues; do not move plant to different location during bloom; stake spikes gently if needed; flowers are often fragrant in evening hours
Rest period
2-4 weeksAfter blooming, plant enters brief rest with reduced growth; spikes may dry back
Slightly reduce watering and feeding; maintain humidity and temperature; rest period naturally supports subsequent blooming cycles
