Adenium arabicum 'D2' × 'Boar' — Squat Fortress Dwarf Hybrid Seeds

D2 × Boar pairs two classic Thai competition lines to build one specific silhouette: a flat, heavily pancaked D2 caudex fortress topped by Boar's dense, rigid, symmetrical branch crown. D2 forces everything horizontal and low. Boar loads the top with a uniform miniature forest of thick, vertical primary branches. Together the result is a squat, wide, heavily crowded dwarf bonsai that reads like a finished competition specimen even at a young stage.

FULL PRODUCT DESCRIPTION

Adenium arabicum 'D2' × 'Boar' (Wild Boar / Moo Pa) is a deliberate pairing of two iconic heavy-boned Thai arabicum lineages, each contributing a distinct structural strength to the seedling population.

The D2 Contribution — Extreme Horizontal Expansion & Hyper-Dwarfism
D2 (Diamond 2 / Petch D2) is celebrated in Thai competition circles for its remarkable "pancake" geometry — forcing the caudex to expand horizontally rather than vertically, maintaining an extremely low profile close to the soil line. It introduces ultra-short internodes and a tendency toward massive, plate-like lateral root spreads.

The Boar Contribution — Rugged Bark Texture, Rigid Symmetrical Branching & Vigor
Named for its tough, resilient, muscular character, the Boar line brings serious structural frame mechanics — a uniform, dense crown of thick, vertical-leaning primary branches from the upper ridge of the caudex, combined with a rustic, heavily textured silver-gray bark patina that gives mature specimens a genuinely weathered, battle-hardened look.

The "Squat Fortress" Silhouette
D2's influence keeps the lower caudex flat and low — a heavy, swollen, flat-bottomed dome with strong lateral roots pushing out into a massive anchoring foot flare. The upper canopy reads like a miniature forest: Boar's high primary and secondary branch count combined with D2's short, stubby, tightly packed internode compression produces a dense, umbrella-shaped crown with no constant pinching required.

Foliage
Broad, thick, highly leather-like leaves in bright emerald to dusty green with prominent pale veins, often carrying a subtle velvet-like pubescence on the underside.

As a hybrid cross, expect a natural spectrum of trait expression across a batch. Top-tier selections combine the full flat D2 pancake base with Boar's dense, rigid vertical crown above it. Others may lean more toward D2's extreme horizontal compression or Boar's rugged bark and branching vigor — both directions produce strong, collectible dwarf specimens.

Zone 6 Notes
Compact dwarf genetics and maximum light intensity are non-negotiable together — drop below full sun and the tightly stacked branch nodes start to stretch, losing the densely packed crown that makes this cross worth growing. I keep D2 × Boar in full unfiltered direct sun outside after May 15 with no shade cloth. The flat, wide, low-slung caudex has significant surface area sitting against the potting media, which makes humidity trapping a real rot risk — I run 85–90% inorganic (premium pumice, black lava rock, coarse perlite) to keep the base dry and aerated. Strict winter dormancy: when foliage drops, water stops completely. A slow-metabolizing dwarf hybrid sitting in cool damp media is a fast path to irreversible root rot. Indoors well before first hard frost in mid-October, dry and cool until active spring growth resumes.

WHAT'S INCLUDED

• Fresh Adenium arabicum 'D2' × 'Boar' seeds (select quantity above)
• Germination instructions included with every order

GROWING BASICS

• Germination temp: 85–95°F
• Germination time: 5–14 days under ideal conditions
• Hardiness: Bring indoors before nighttime temps reach 50°F
• Light: Maximum unfiltered direct sun or high-output full-spectrum LED — compact dwarf genetics etiolate rapidly in low light
• Media: 85–90% inorganic (premium pumice, black lava rock, coarse perlite) — flat pancake caudex is rot-vulnerable if humidity is retained underneath
• Dormancy: Strict hard winter rest — zero water when foliage drops; cool damp media causes irreversible root rot in slow-metabolizing dwarf lines
• Skill level: Intermediate — high phenotypic reward but light and substrate discipline are non-negotiable
