Hoya 'Microdwarf' (NS12-323) – Tiny-Leaf Trailing Houseplant for Small Spaces

Don’t let the size fool you. Hoya ‘Microdwarf’ (NS12-323) is one of the smallest-leaf hoyas in cultivation, and it knows exactly how to turn heads. Its rounded, pea-sized foliage grows densely along thin, trailing stems, creating a soft, elegant drape across shelves or containers. Under strong light, the deep green leaves can blush red—adding a hint of color contrast to an already striking form.

Whether you’re short on space or want something sculptural for a tight corner, this compact cultivar is made for growers who love detail. It rarely blooms, but when it does, you’ll see delicate starry flowers that reward patient care.

What makes ‘Microdwarf’ a favorite for small-space growers

  
Leaf size: Micro-sized—only 1–2 cm long on average
  
Foliage color: Green with potential red blush under bright light
  
Growth habit: Trailing and compact—not a climber

How ‘Microdwarf’ behaves in indoor setups

This cultivar’s exact wild origin isn’t known, but it behaves like many epiphytic hoyas: it prefers airy substrate, moderate humidity, and consistent warmth. It doesn’t climb and doesn’t need support. That makes it perfect for mobile displays or spaces where vining isn’t ideal.

Its small root system prefers smaller pots and dries out faster, helping avoid the common overwatering trap. In bright conditions, you'll often see a reddish flush appear naturally on the leaf tips.
