Before You Buy
Species-specific things to check when evaluating a listing
- Inspect new growth carefully for thrips — check the undersides of unfurling leaves for tiny dark insects or silvery streaking, as velvet anthuriums are a primary target
- Roots should be firm and pale — mushy or dark roots indicate rot often caused by poor transit conditions
- Avoid plants with more than one yellowing leaf; minor leaf loss in transit is normal but multiple yellows suggest stress before shipping
- Request a photo of the most recently unfurled leaf to judge current health — a crispy or damaged newest leaf is a red flag
Anthurium clarinervium × pedatoradiatum 'Delta Force' Morphology
About Anthurium clarinervium × pedatoradiatum 'Delta Force'
Anthurium 'Delta Force' is a deliberate hybrid created by Steve Nock of Ree Gardens, Miami, Florida, in the 1990s — a cross between Anthurium clarinervium and Anthurium pedatoradiatum. Delta Force was the sole seedling from the cross to produce the distinctive deltoid (triangular) leaf form with a sharply acuminate tip, a geometry found in no other common Anthurium. From A. clarinervium it inherits bold, luminous white venation against a deep dark-green coriaceous blade; from A. pedatoradiatum it inherits the triangular leaf outline. The result is a compact, self-heading terrestrial velvet anthurium valued for its architectural leaf shape and vein contrast. Still relatively scarce in the hobby, Delta Force commands premium prices and is increasingly sought by serious velvet anthurium collectors.

Propagation Guide
How to Propagate Anthurium clarinervium × pedatoradiatum 'Delta Force'
Root in a closed high-humidity environment. Mature specimens may produce basal offshoots that can be carefully divided. Patience is essential — establishment is slow.
Care Guide
Anthurium clarinervium × pedatoradiatum 'Delta Force' Care Guide & Growing Conditions
Very chunky, well-aerated mix: 40% orchid bark, 30% perlite, 20% sphagnum moss, 10% activated charcoal. Anthuriums suffocate in dense soil — roots need airflow.
Water when the substrate is nearly dry throughout. Less is more — overwatering is the primary killer of velvet anthuriums. Always use room-temperature water.
70–85% is essential. Below 60% causes stunted growth and curling leaves. A dedicated humidifier is strongly recommended for UK growers.
Low-nitrogen fertiliser (e.g. 5-10-10 or orchid fertiliser) at quarter strength every 3–4 weeks. High nitrogen produces lush but weak growth susceptible to pests.
Reluctantly — only when completely root-bound (every 2–3 years). These plants dislike disturbance and may sulk after repotting.
Common Problems
Yellowing leaves
Overwatering or root rot
Remove from pot, trim affected roots, repot into fresh dry substrate and reduce watering
Curling or crispy leaf edges
Low humidity or cold draughts
Increase humidity above 70% and move away from cold windows
Thrips
Common on velvet-leaf anthuriums; hard to detect early
Inspect new growth and leaf undersides regularly; treat with neem oil or systemic insecticide at first sign
Steve Nock's Triangular Cross
Anthurium 'Delta Force' is a hybridization legend. Bred in the 1990s by Steve Nock of Ree Gardens in Miami, it is a cross between A. clarinervium and A. pedatoradiatum. Only a single seedling inherited this precise, geometric triangular outline with high-contrast white venation. Dr. Thomas Croat, in his extensive reviews of Anthurium hybrids, described Delta Force's morphology as a unique genetic recombination where the pedate lobe genes of pedatoradiatum were suppressed, leaving a stark, straight deltoid edge. It remains incredibly rare because it must be propagated via division—tissue culture often fails to capture the true leaf shape.
