🌿 Hoya archboldiana — tropical bellflower from Papua

Hoya archboldiana is one of the most spectacular hoyas in the world, prized for its huge flowers — bell-shaped, up to 7-8 cm in diameter, intense pink to burgundy, with a contrasting white central corona. The species bears the name of explorer Richard Archbold, who led botanical collecting expeditions in Papua New Guinea in the 1930s.

Leaves are large, thick, fleshy, deep green with prominent central vein. It grows as a vigorous vine in the trees of mountain tropical forests. A showpiece for passionate collectors — the flowers instantly attract attention through size and color.
