Phalaenopsis speciosa 'Miki Purple' (fragrant)

Phalaenopsis speciosa 'Miki Purple' is a selection of the species Phalaenopsis speciosa, native to the Andaman Islands, Nicobar Islands, and Borneo, from low elevations. In recent taxonomy, speciosa is often treated as a synonym of Phalaenopsis tetraspis; both names remain in use in commerce. The plant is medium-sized, approximately 15–20 cm tall, with 10–25 cm leaves and 2–5 lateral, arching or semi-pendent flower spikes. The flowers are waxy and fragrant, usually around 4.5 cm across, with natural variation in color and pattern.

The 'Miki Purple' selection retains the fragrance and floral type of the speciosa/tetraspis group. Flower color may vary naturally.

It needs moderate to bright, filtered light, approximately 18,000–22,000 lux, protected from harsh sunlight and, ideally, around 12 hours of light per day. Suitable temperatures are around 22–28°C during the day and 18–22°C at night; a 3–4°C difference between day and night helps promote flowering. It does not require a severe rest period.

Water when the substrate dries out, then allow the water to drain completely. Do not let water stagnate between the leaves. In a pot, humidity of 55–60% is usually sufficient; when mounted, aim for around ~70%. During active growth, fertilize with a diluted solution (about half the recommended dose) after watering, approximately every third watering, using orchid fertilizer. Use medium-grade, well-aerated bark. A Phalaenopsis substrate is suitable if it dries out at the right rate for your home. Repot after flowering, when new roots appear.

If the plant produces many spikes but few flowers, check the light and fertilization. Bud drop is often caused by dry air, sudden relocation, or damaged roots. Soft roots and a sour smell indicate overwatering.
