Adenium arabicum 'DHA Medusa' — Wide-Caudex Dorset Horn Thai Hybrid Seeds

Adenium arabicum ‘DHA Medusa’ is a highly sought-after arabicum selection bred specifically for extreme caudex development. This variety produces a wide, flattened base with a distinctly muscular branching structure — multiple thick, gnarled arms emerging from a single, imposing root system that pushes upward as the plant matures.

Unlike standard arabicum seedlings, Medusa puts its energy into horizontal caudex expansion early. Growers in colder climates can expect meaningful base development within the first growing season when provided adequate warmth, bright light, and a fast-draining media.

What makes DHA Medusa stand out:

∙ Broad, squat caudex form — one of the widest bases in the arabicum class

∙ Dense, multi-branch canopy structure with thick, succulent stems

∙ Heavy surface root system with strong visual character even in young plants

∙ Reliable germinator from quality seed stock
This is a grower’s plant — the kind of arabicum that rewards patience and proper culture with a specimen-quality caudex over time.

Sold as fresh seed. Each order includes 10 seeds. Germination instructions included.

What You'll Need to Grow These

Seeds are only half the equation — germination success comes down to the right setup. Here's what I use:

∙ Desert Oasis Potting Media — the fast-draining inorganic mix built for Adenium, Plumeria, and caudex seedlings once they're up and potted on.

∙ Luxbird Seed Germinator & Propagation Kit — bottom heat and a humidity dome, the two things that push arabicum germination toward the 90%+ range.

∙ 5×5 Germination Tray — sized for clean single-variety sowing so nothing gets crossed up.
