Phal schilleriana Overview
A popular species among orchid collections. It’s often fragrant. It’s vigorous. The flower really embraces that “moth orchid” look. But above all, the leaves are spectacular with their mottled-leaf banding and patterns.
The type I have is likely from the Sabah region of Malaysia, and it’s frequently called the Silver-Leaf schilleriana because the leaves are nearly fully mottled rather than banded. The banded variants come from Luzon and other smaller surrounding islands of the Philippine Archipelago.
In 2018 it bloomed with 14 flowers on one spike; the following year (2019) it bloomed with 27 flowers on 2 spikes and I expect this count to continue jumping up each year (assuming I don’t screw anything up). The plant has the potential to have hundreds of blooms and can make an impressive display.
Phalaenopsis schilleriana Care
Potting mix – these orchids need an open and airy media. Some sphagnum can be used, but do so at a lower ratio (<20%)
Light – This phal is the grown in the brightest area of my East-facing window. It gets full sun until nearly noon. The only caveat to this, my windows may be quite thick and therefor “direct sun” may not mean “full sun.”
Watering – schilleriana comes from a region that experiences seasonal changes. Wet / dry cycles are required for this plant – it’s not a good candidate for water culture.
pH – I started adjusting my tapwater pH from 7.5 down to 5.8 using “pH Down” (phosphoric acid). My phal schilleriana responded the most profoundly…in a single season the next set of leaves doubled in length from the previous year. As a result of the marked size jump, it’s now working on 2 spikes at the same time.
