Hoya ‘Microdwarf’ (NS12‑323) – Micro-Trailing Hoya 
 
Hoya ‘Microdwarf’ (NS12‑323) is a slow-growing, trailing hoya with ultra-compact, slightly pointed leaves — typically just ca. 2 cm long. The vines stay low and contained, draping gently over shelf edges or open terrarium borders without ever climbing.
 
Under bright light, the matte green leaves may develop a soft red blush, adding subtle contrast without overwhelming your space. With its tidy scale, sculptural growth, and low maintenance needs, this is a dream plant for growers who love detail and form.
 
Its floral traits remain unknown — no bloom has ever been recorded in cultivation — but this plant doesn’t need flowers to stand out.
