RLC. King of Taiwan 'Ta-hsin 1' AM/AOS - fragrant

RLC. King of Taiwan ‘Ta-hsin 1’ AM/AOS is a large Rhyncholaeliocattleya hybrid, valued for its violet-lilac to ruby flowers, with an intense yellow lip, red markings, and prominent veining. The flowers are fragrant and usually measure 13–19 cm; on a well-established plant, under excellent conditions, they can reach up to 23 cm. The AM/AOS distinction confirms the quality of this clone, but flowering still depends on light, mature pseudobulbs, and active roots.

In older horticultural literature, it may appear as Brassolaeliocattleya or under other nothogenus names. The abbreviation RLC. comes from Rhyncholaeliocattleya, the group that brings together hybrids with Rhyncholaelia and Cattleya parentage. For home care, the plant’s behavior matters more: vigorous growth, pseudobulbs that must be allowed to mature, and a need for stronger light than a Phalaenopsis.

Light is the key to flowering. Place the plant near an east-, west-, or filtered south-facing window, acclimating it gradually if it will receive direct sun. Light green leaves generally indicate good light; very dark leaves and elongated growth show that the plant is being kept too shaded. Hot summer sun can scorch the leaves, and a plant moved suddenly from shade into full sun can develop spots easily.

Medium to warm temperatures are suitable, with a slight difference between day and night and good ventilation. Water thoroughly when the substrate is approaching dryness, then allow the water to drain completely. Slightly wrinkled pseudobulbs can indicate prolonged thirst, but soft roots and an affected base show that the substrate is staying wet for too long. During the growing season, fertilize with a diluted solution after watering, using orchid fertilizer.

RLC. King of Taiwan has roots that require air circulation. Use a coarse-grade mix containing pine bark, pumice, and mineral material; coconut fiber can be useful if the growing location is very dry. An aerated orchid substrate is suitable if you adapt it to the size of the roots. Repot after flowering, when new roots appear, and avoid using a pot that is much too large.

A mature new growth can support 2–5 flowers. Do not cut green pseudobulbs after flowering: they remain reserves for the plant. Cut only the dried flower spike. If the plant does not flower, check the light first, then the roots and the maturity of the pseudobulbs. Buds that stop developing can appear after repeated relocations, sudden drought, or very dry air.
