Phalaenopsis lueddemanniana 'Dark Red Taiwan'

Phalaenopsis lueddemanniana 'Dark Red Taiwan' is a selection of the species from the Philippines, with waxy flowers in dark red shades and an intricate pattern on a lighter background. The species was described by Reichenbach in 1862, named after Lueddemann, and grows epiphytically around Manila at low elevations in a warm, humid climate. It is a small to medium-sized plant, with fleshy, oblong-elliptic leaves measuring 15–30 cm. The flowers are fragrant.

The flowers are 5–6 cm across, with a waxy texture, a star-shaped form, and can last for nearly two months. The flower spike usually produces 3–5 flowers. The fragrance is delicate and sweet, often intense. The species reblooms easily on green spikes and produces keikis; keep the spikes after flowering and cut only the dried sections. Flowering is more frequent from spring through summer.

Light should be moderate, approximately 10,000–12,000 lux, with partial shade. Warm temperatures are suitable, generally 21–34°C, provided there is adequate humidity and ventilation. It does not need a severe cool rest period. In winter, if light levels decrease, you can lengthen the intervals between waterings, reduce humidity to around 60–70%, and stop fertilizing, without allowing the substrate to remain completely dry for long periods.

Water when the substrate is nearly dry, keeping it slightly moist but not waterlogged. During active growth, many plants tolerate more frequent watering than an easy-to-dry Phalaenopsis hybrid. Fertilize with a diluted solution after watering, using orchid fertilizer. Use an airy mix of medium-grade bark, optionally with a little sphagnum. A Phalaenopsis substrate is suitable if it dries at the rate appropriate for your home. Repot after flowering, when new roots appear.

If keikis develop on the flower spike, you can allow the plant to form a fuller clump or remove the keiki once it has its own roots. Soft roots and a sour smell indicate excess water. Soft leaves may indicate thirst or roots that are no longer absorbing water. Buds can be affected by sudden moves, very dry air, or cold temperatures.
