Before You Buy
Species-specific things to check when evaluating a listing
- Check the growing point (the newest, unopened leaf) for firmness — softness here usually means rot has already reached the crown
- Look at the root system through the drainage holes if possible; healthy roots are firm and pale, not brown and mushy
- Confirm the leaf reads as a clean deltoid triangle with a sharp apex — a rounder or less defined shape suggests mislabelled or off-type stock
- Ask about leaf count and node count relative to price, the usual yardsticks collectors use to judge value on a velvet-leaf hybrid
Anthurium clarinervium × pedatoradiatum 'Delta Force' Morphology
About Anthurium clarinervium × pedatoradiatum 'Delta Force'
A single seedling from Steve Nock's 1990s cross of Anthurium clarinervium and Anthurium pedatoradiatum at Ree Gardens, Miami, produced the sharply triangular, deltoid leaf that gives 'Delta Force' its name — a geometry no other common Anthurium shares. From clarinervium it takes bold white venation set against a deep, coriaceous dark-green blade; from pedatoradiatum, the acuminate triangular outline. The result is a compact, self-heading terrestrial velvet hybrid.
Origin

8-14 months
Divides cleanly at the base once a plant has produced multiple growth points — separate with a clean cut, dust with cinnamon or a fungicide, and pot each division into fresh, chunky aroid mix. Top cuttings with at least one node and aerial root also root reliably in damp sphagnum.

Care Guide
Anthurium clarinervium × pedatoradiatum 'Delta Force' Care Guide & Growing Conditions
A chunky, open aroid mix — equal parts orchid bark, perlite and coco chunk, with a smaller portion of moss or coco coir for moisture retention — mimics the loose, well-aerated leaf litter these grow in naturally. Standard potting compost alone stays too wet around the roots.
Water thoroughly, then let the top third of the mix dry before watering again. Velvet-leaf anthuriums are more sensitive to root rot than most houseplants, so err on the side of underwatering rather than keeping it constantly damp.
High, 60-80%. Consistent humidity keeps the leaf's velvet texture and colour contrast at their best; average room humidity alone tends to show it within a few weeks.
Feed at quarter to half strength every 2 weeks in the growing season with a balanced, nitrogen-forward fertiliser; drop to monthly over winter. Heavy fertilising scorches the fine root system faster than it helps growth.
Repot every 12-18 months, or when roots fill the pot and start pushing the plant upward. Choose a pot only slightly larger than the current one; these dislike being over-potted into a large volume of slow-drying mix.
Common Problems
Root rot
Substrate that stays wet, often from a mix that's too dense or a pot with poor drainage
Repot into a chunkier mix immediately, trim away any mushy roots, and let the plant recover in a smaller pot before sizing up again
Thrips or spider mite damage
Dry air and still conditions, especially indoors over winter
Increase humidity and airflow together, and treat visible pest damage with a systemic or contact treatment rather than water alone
Blurred or muted vein contrast
Insufficient light for the venation to develop strongly
Move to brighter indirect light; the sharpest vein contrast on this hybrid develops under good light, not deep shade

Field Notes
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 is propagated by division, since tissue culture often fails to capture the true leaf shape.
