Anthurium subsignatum × ‘Ace of Spades’ is a Vietnamese hybrid combining the rugged, textured foliage and dark tones of A. subsignatum with the dramatic, velvet‑leaf form and deep colouring of Ace of Spades. Leaves tend to emerge softly, showing contrast in veins, then mature into more heart‑shaped blades with a dark sheen. 

Native to:
Since this is a hybrid, it has no true “native habitat,” but its parental species come from tropical Central/South American forest understorey environments.

Water:
Water when the top ~ one‑third of the potting mix begins to dry out. The medium should retain some moisture but never stay soggy. Use an airy, well‑draining substrate (for example, bark, perlite, maybe some fine sphagnum or composted organic matter) to ensure roots get airflow. Avoid letting the plant sit in water; drain thoroughly after watering. Overwatering leads to root rot, under‑watering will reduce leaf colour and shrink new leaf size.

Light:
Bright filtered light is best. Indirect light that’s strong but diffused will help bring out the deep tones and vein contrast. Avoid harsh direct midday sun which can scorch or bleach the dark leaf parts. If light is weak, leaf colour will become more uniform and dull, and new growth may be slower and paler. Morning or late afternoon direct light with filtering (or through shade cloth / sheer curtain) can be tolerated.

Humidity:
High humidity is advantageous — around 65‑80 % works well. Dry air tends to dull the sheen of the leaves, make leaf edges brown, and reduce contrast in veins. In a dry indoor environment (especially in winter), use measures like humidifiers, pebble trays, grouping with other plants, or keeping in a humid enclosure to maintain good moisture in the air.

Temperature:
Maintain warm and stable conditions. Ideal daytime temperatures around 18‑27 °C is good. Avoid letting temperatures fall below ~ 15‑16 °C, which may stress the plant. Sudden fluctuation (cold drafts, hot dry air) should be avoided, as they can cause leaf damage or slow growth.
