Phalaenopsis speciosa 'Purple Dream'

Phalaenopsis speciosa 'Purple Dream' is a selection of the species Phalaenopsis speciosa, from the Andaman Islands, Nicobar Islands, and Borneo, found at low elevations. In recent taxonomy, speciosa is often treated as a synonym of Phalaenopsis tetraspis; both names remain in use in the trade. 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 5.5 cm across, with natural variation in color and pattern.

The 'Purple Dream' selection is also frequently listed as Phalaenopsis tetraspis 'Purple Dream'. It has compact to medium growth and intense coloration on its fragrant flowers.

Plants may have leaves with minor cosmetic defects; these do not compromise the plant's health if the roots are active.

Requires moderate to bright, filtered light, approximately 18,000–22,000 lux, with protection from strong 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 need a severe rest period.

Water when the substrate dries out, then allow the water to drain completely. Do not allow water to 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 a medium-grade, airy bark mix. A Phalaenopsis substrate is suitable if it dries at a rate appropriate for your home. Repot after flowering, when new roots appear.

If the plant produces many spikes but few flowers, check the light and fertilization. Dropping buds often indicates dry air, a sudden change of location, or damaged roots. Soft roots and a sour smell indicate overwatering.
