{"product_id":"adenium-arabicum-yakdum-black-giant-thai-hybrid-seeds","title":"Adenium arabicum 'Yakdum' — Black Giant Thai Hybrid Seeds","description":"\u003cp\u003eYakdum means \"Black Giant\" in Thai — and it delivers on both words. Coming out of the Arabicum House \/ Mr. Ram breeding networks, this elite line combines aggressively massive, giant-scale arabicum skeleton with high-expression dark charcoal skin genetics. This is not a dwarf line. It builds enormous, heavily flared trunk mass and dense self-branching canopy, all wrapped in a smoky, dark charcoal-bronze-purple bark.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eFULL PRODUCT DESCRIPTION\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eAdenium arabicum 'Yakdum'\u003c\/strong\u003e (also seen as Yak Dum or Chada Dum variants) comes out of some of the most respected breeding networks in Thailand — Arabicum House and Mr. Ram's program — with a single objective: combine a massive, giant-scale arabicum skeleton with intensely dark skin expression.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eThe Bark — The \"Dum\" Aesthetic\u003c\/strong\u003e\u003cbr\u003eYakdum's signature is a deeply saturated dark charcoal-gray to matte bronze-purple epidermis. Under intense UV, the skin develops a smoky, weathered patina that contrasts sharply against the bright green canopy. This is a pigmentation-first line, and the bark is the entire visual argument.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eGiant Yet Proportional Anatomy\u003c\/strong\u003e\u003cbr\u003eUnlike DHA dwarf lines, Yakdum carries real \"Yak\" (Giant) genetic potential — a massive, muscular, incredibly heavy trunk base. It doesn't shoot vertical into a leggy tree; instead it builds wide, growing into a heavily flared dome with serious structural presence at every stage of development.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eBranching and Internodes\u003c\/strong\u003e\u003cbr\u003eHigh-density self-branching is a hallmark of this line. A dense, structural ring of thick, stubby primary branches with tightly stacked internodes creates a layered crown that naturally mimics the look of an ancient, heavy-wooded canopy.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFoliage and Roots\u003c\/strong\u003e\u003cbr\u003eBroad, thick, slightly obovate leathery leaves with dark purple pigmentation picking up in the leaf margins and veins under high light stress. At the base, thick, heavy lateral roots (nebari) flare wide, locking the massive dark trunk into the substrate.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFlowers\u003c\/strong\u003e\u003cbr\u003eClassic, high-contrast light pink to bright fuchsia star-shaped blooms — the bright flowers against the dark bark are a striking combination at peak flush.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eZone 6 Notes\u003c\/strong\u003e\u003cbr\u003eI treat Yakdum exactly like my other dark-skin lines on light: maximum unfiltered direct sun, no exceptions. Drop below full sun intensity and the melanin production slows, the bark reverts toward smoky dull green, and the whole point of growing this line disappears. Outside in the hottest, brightest spot after May 15. Because it has the capacity to put on serious tissue weight fast during peak summer, I run it in an 80–90% inorganic mix — premium pumice, black lava rock, coarse perlite — so the massive root system never sits in stagnant water. Winter dormancy is non-negotiable and strictly dry: when foliage drops, water stops completely. A dark-skinned, massive arabicum caudex held in cold damp media is the fastest path to irreversible rot I know of. Dry, cool, zero water until active spring growth resumes.\u003c\/p\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eWHAT'S INCLUDED\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFresh Adenium arabicum 'Yakdum' seeds (select quantity above)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eGermination instructions included with every order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr class=\"border-border-200 border-t-0.5 my-3 mx-1.5\"\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eGROWING BASICS\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eGermination temp:\u003c\/strong\u003e 85–95°F\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eGermination time:\u003c\/strong\u003e 5–14 days under ideal conditions\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHardiness:\u003c\/strong\u003e Bring indoors before nighttime temps reach 50°F\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLight:\u003c\/strong\u003e Maximum unfiltered direct sun or high-output full-spectrum LED — bark reverts to dull green without it\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMedia:\u003c\/strong\u003e 80–90% inorganic (premium pumice, black lava rock, coarse perlite)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDormancy:\u003c\/strong\u003e Strict dry winter dormancy — cease watering completely when foliage drops; damp cold media causes rapid caudex rot\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSkill level:\u003c\/strong\u003e Intermediate — high vigor but dark-skin pigmentation and dormancy protocol require discipline\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"American Adenium","offers":[{"title":"Default Title","offer_id":51003481423908,"sku":null,"price":20.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0742\/9655\/7604\/files\/YakDum.png?v=1782866143","url":"https:\/\/www.americanadenium.com\/products\/adenium-arabicum-yakdum-black-giant-thai-hybrid-seeds","provider":"American Adenium","version":"1.0","type":"link"}
