The structural symmetry of a royal Thai crown, wrapped in brooding dark bark — a collector-grade line that delivers both in a single plant.\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 'Chadadum'\u003c\/strong\u003e (also seen as Chada Dum or Chadatungnang Dum) is an elite Thai arabicum cultivar built around a single, precise visual concept: perfect radial crown symmetry in pitch-dark skin.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eThe Royal Crown Silhouette\u003c\/strong\u003e\u003cbr\u003eThe defining structural trait is the self-branching geometry. Chadadum drops a perfectly uniform, symmetrical ring of thick, stubby primary branches straight from the upper rim of the caudex — growing upright and slightly outward at uniform angles, mirroring the multi-tiered spikes of a traditional Thai royal crown. The internodes are hyper-shortened, keeping the canopy tight and dense without corrective pruning.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eThe \"Dum\" Skin Patina\u003c\/strong\u003e\u003cbr\u003eRather than the smooth silver-gray or pale green skin of classic arabicums, Chadadum expresses a high concentration of dark pigments — bark matures into rich, matte charcoal-gray, deep oil-slick bronze, or dark purple-black coloration. The structural canopy takes on a stark, weathered, brooding appearance against the dark wood.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eCaudex and Bone Structure\u003c\/strong\u003e\u003cbr\u003eHeavy, muscular, wide-set base that stays compact and balanced — lateral mass in proportion with the pristine vertical branching above rather than sprawling into a loose mound.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eFoliage and Flowers\u003c\/strong\u003e\u003cbr\u003eBroad, fleshy, slightly obovate leaves with a velvety texture, frequently flushing deep crimson or violet along veins and leaf edges under high UV exposure. Standard star-shaped light pink to bright fuchsia flowers provide a brilliant, high-contrast pop against the dark wood at bloom time.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eZone 6 Notes\u003c\/strong\u003e\u003cbr\u003eBoth the crown symmetry and the dark bark depend entirely on unfiltered UV intensity — there is no compromise on this one. Low light causes the branches to reach and stretch, permanently breaking the uniform crown geometry, while the dark melanin production stalls and the bark reverts to smoky green. I grow Chadadum in my most intense direct-sun position outside after May 15 with no shade cloth and no filtered greenhouse plastic. Substrate is 80–90% inorganic (premium pumice, black lava rock, coarse perlite or hard-fired clay) — the root system on dark-skin dwarf lines has zero tolerance for retained moisture. Strict winter dormancy: when foliage drops, water stops completely. Cold damp media and a dark-skinned dwarf root zone is a fast path to fatal rot. Dry, cool, zero water until active spring growth resumes. Indoors before first hard frost in mid-October.\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 'Chadadum' 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 Unfiltered maximum direct sun or high-output full-spectrum LED — non-negotiable for both crown symmetry and dark bark expression\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 or hard-fired clay)\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDormancy:\u003c\/strong\u003e Strict hard winter rest — zero water when foliage drops; cold damp media causes rapid fatal 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 to advanced — light discipline and dormancy protocol are critical to preserving both aesthetic traits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"American Adenium","offers":[{"title":"Default Title","offer_id":51003597684772,"sku":null,"price":17.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0742\/9655\/7604\/files\/Chadadum.png?v=1782869099","url":"https:\/\/www.americanadenium.com\/products\/adenium-arabicum-chadadum-black-crown-thai-hybrid-seeds","provider":"American Adenium","version":"1.0","type":"link"}
