Name: Paphiopedilum 'Black Jack'
Parents / Hybridization: Hybrid of the Maudiae group (Vinicolor forms from the Paphiopedilum-Maudiae complex, including, among others, Paphiopedilum callosum, Paphiopedilum lawrenceanum, and Paphiopedilum superbiens)
First description: Cultivated hybrid (horticultural selection from the Maudiae/Vinicolor lineage).
Origin / Distribution: Horticultural origin. The wild species underlying the Maudiae section originally come from the shaded, moist rainforest floors and humus layers of Southeast Asia (including Vietnam, Malaysia, and Borneo).
Location / Habitat: Terrestrial to humicol-lithophytic growth habit. Prefers a partially shaded to shaded location without direct, intense sunlight. Requires a fine, very well-draining substrate (for example, fine pine bark with Sphagnum moss and some perlite). Cultivation takes place in temperate to warm conditions (18–25 °C) with consistent moisture and good air circulation.
Description & Notes: Paphiopedilum 'Black Jack' is a spectacular selection from the Vinicolor lady slipper group. The flower impresses with a very dark, glossy dorsal sepal and a deep dark red to almost black-colored "slipper" (lip). Even outside the flowering season, the plant is extremely decorative due to its attractive silvery-dark green marbled foliage.

Since Paphiopedilum does not have pseudobulbs for water storage, the root ball must never completely dry out. The substrate should always be kept slightly moist, while waterlogging must be strictly avoided. Ideally suited for cultivation on a shaded windowsill or in temperate display cases.
