Where it comes from
A Florida nursery, and past that the record stops. Sellers consistently credit it to Silver Krome Gardens and to William Rotolante, who named it.12 Nothing above that tier mentions the plant at all: not Kew, not the International Aroid Society’s registry, not Exotic Rainforest, and not either of the long specialist surveys of velvet and pebbled anthuriums — one of which discusses its putative parent at length and never names it.3
It is not registered, and that negative is unusually solid. The registry serves records for accepted, rejected and pending cultivarscultivarA plant selected and propagated by people rather than described from the wild.

There is a wrinkle there worth enjoying: Bill Rotolante is both the breeder credited with naming this plant and the registrar the International Society for Horticultural Science lists for Araceae,7 and he registered ‘Jack of Clubs’ with full parentage in 2021.5 The gap is not for want of knowing how.
How it arose is contested three ways, all of them retail copy. One account has it a hybrid seedling of ‘Ace of Spades’ × ‘Red Leaf’ that turned up as a tissue-culturetissue cultureGrowing plants from a few cells in sterile jars of nutrient gel. It is how a rare cultivar becomes a supermarket plant, and why prices for some of them collapse.Glossary accident;8 another has it a spontaneous tissue-culturetissue cultureGrowing plants from a few cells in sterile jars of nutrient gel.

Compounding it, ‘Ace of Spades’ is itself registered as a select form of an unknown jungle-collected plant,4 so even the alleged parent has no documented parentage.
Naming and description
The “Queen” is borrowed. The true Queen Anthurium is Anthurium warocqueanum T.Moore, described in 1878 from Colombia — a pendent epiphyteepiphyteA plant that grows on another plant, taking nothing from it — perched in bark and leaf litter rather than rooted in soil. It is why so many houseplants want an airy mix rather than compost.Glossary with strap-shaped blades approaching a metre.1011 This is a compact plant with rounded, heart-shaped leaves, and nothing connects the two.
What the name actually belongs to is a playing-card series out of the same nursery. The registry records ‘Jack of Clubs’ as named after a playing card for its club-like leaf shape, and ‘Ace of Spades’ for the colour and shape of its foliage.54 A heart-shaped leaf gets the hearts card. That is the whole derivation, and it is a better story than the borrowed royalty.
On the leaf itself: velvety or leathery, dark, with deep prominent veins.112 It belongs with the dark velvet anthuriums rather than the pebbled ones — a distinction worth holding on to, because the two groups look similar in a photograph and the pebbled plants are a different thing entirely. Every plant in the trade is a clonecloneEvery plant propagated by cutting or division from one original, and so genetically identical to it. Most named cultivars are a single clone.Glossary.2
Fun facts
- The registrar did not register it. The man credited with naming this plant is the registrar the ICRAICRAAn International Cultivar Registration Authority: the body that registers cultivar names for one group of plants. Most genera have none, which is why so many trade names are unregistered.Glossary system lists for the whole arum family,7 and he has used that registry for other plants from the same nursery in the same series.5 Which is a fair measure of how optional cultivarcultivarA plant selected and propagated by people rather than described from the wild. Written in single quotes after the species — Monstera deliciosa 'Thai Constellation' — and never italicised.Glossary registration is in this trade: even the person running it does not always bother.
- Two incompatible origin stories are circulating as fact. A hybrid seedling is a cross between two plants; a sportsportA shoot that appears on a plant carrying a mutation the rest does not have. Propagated on its own, it becomes a new cultivar.Glossary is one plant mutating. Sellers state each with equal confidence.89 Where a plant has no registration, the origin story is whatever the last listing said, and the confident tone is not evidence.

Care
Plant care- Light
- Bright indirect, never direct midday sun. Commercial production runs at 1,000-2,500 foot-candles under heavy shade; indoors the useful band is 100-500 foot-candles, and 100 is a floor rather than a target — plants hold on there but do little.
- Water
- Water when the top 5 cm is approaching dry, and never leave the pot standing in water. Keep water off the foliage: the blight bacterium swims across a wet leaf surface, so raising ambient humidity and misting are different acts with opposite effects.
- Humidity
- High — 70 to 80 per cent is the only figure any university publishes, and it is for commercial flamingo flowers rather than the velvet species. Do not chase 90 per cent and above: transpiration stops in saturated air, which strands calcium and invites rot. Nobody has published a number for the velvet-leaved species at all.
- Temperature
- 65-85 °F (18-29 °C) all year, with a hard floor around 55 °F (13 °C). They do not want a cool winter rest and will not thank you for one.
- Substrate
- Coarse and largely soil-free — bark and perlite with only a minority of fines, at pH 6.0-6.5. The roots carry a velamen, the same absorptive sheath orchid roots have, which is the anatomical reason a dense mix suffocates them.
- Fertilizer
- Weak and frequent: a balanced feed at about 50 ppm nitrogen monthly indoors. Scale the rate to the light rather than the calendar — a plant in a dim room on a summer schedule is being over-fed.
- Propagation
- Division and offsets are reliable. Stem cuttings work on the species that build a visible stem with aerial roots. Seed must be sown fresh and takes around three years to flower. Sterilise the blade between plants, every time.
- Dormancy
- None. Growth slows in low winter light — water and feed less, but keep them warm.
- Common problems
-
- Bacterial blight: yellow V-shaped lesions spreading from the leaf margin, then blackening. There is no cure, it can sit latent for months in a healthy-looking new plant, and it is the reason to quarantine and to never reuse an uncleaned blade
- Brown crisp leaf tips are usually dry air or accumulated fertiliser salts rather than underwatering
- Thrips leave stippled silvery new growth; scale and mealybugs hide where the petiole meets the stem
- Collapse at the base with soft brown roots is rot — Pythium, Phytophthora or Rhizoctonia — and almost always follows a dense mix or a pot left standing in water
- No flowers on a flowering type means too little light, though the foliage species are not grown for flowers at all
- Every part carries calcium oxalate crystals: the sap irritates skin and eyes, and a chewed leaf burns the mouth
