Phalaenopsis Mini Mark 'Sunsplash' JS/AOS

Phalaenopsis Mini Mark 'Sunsplash' JS/AOS is a multispecific hybrid created by Breckinridge in 1992 from Phalaenopsis philippinensis (50%), P. maculata (25%), and P. lobbii (25%), through the Micro Nova hybrid. It is prized for its small to medium-sized white flowers with orange freckles and an orange-caramel lip. The leaves are usually 10–15 cm long. It can produce multiple flower spikes and bloom in several seasons, most often from autumn through spring. The flowers often last at least 3 months.

It is adaptable to a range of light conditions: bright filtered light or partial shade. It does well on a windowsill; on a south- or west-facing windowsill, protect the plant from strong summer sunlight. Typical indoor temperatures are suitable, approximately 18–30°C, with nights slightly cooler than the daytime. Humidity of 50–70% helps the buds develop; below these levels, growth and flower spikes may stall, and buds may drop, especially above 25°C when the air is dry.

Water when the potting medium has dried out thoroughly, not just on the surface, then allow all excess water to drain away. Do not leave the pot standing in water. During active growth, fertilize every one to two weeks with a diluted orchid fertilizer after watering. It does not need a special rest period to flower.

It grows well in a pot or mounted on a plaque. In a pot, use bark with a little sphagnum moss or a similar airy mix. A Phalaenopsis potting mix is suitable if it dries out at the right rate for your home. Repot every 2–3 years, after flowering, when new roots appear, not during the peak bud season. Compacted potting medium suffocates the roots and leads to limp leaves and weak flower spikes.

If the plant does not flower, check the light, the age of the plant, and the condition of the roots. Falling buds often indicate dry air, a sudden change in location, or irregular watering. Soft roots and a sour smell indicate overwatering.
