What Is Tiny-leaf Porcelain Flower and Where Does It Come From?
Hoya curtisii is a miniature wax plant from Southeast Asia (Thailand, Malaysia, Borneo and the Philippines), where it grows as a creeping epiphyte on trees. Its thin, hairy stems carry small spade-shaped leaves, only about 2 cm long, olive green flecked with silver; in strong light the leaves blush red or maroon. The stems first form a dense mat and then trail over the pot edge, which makes it a good small hanging plant. Mature plants produce tight round clusters of tiny, fuzzy, cream to pale yellow flowers with a white center, with a light lemony scent.
How to Propagate Tiny-leaf Porcelain Flower?
Stem cuttings
Do not damage the aerial roots; they help the cutting root faster. A clear bag or box over the pot raises humidity.
- 1 Cut a 5-10 cm piece of stem with a few nodes and aerial roots
- 2 Remove the lowest one or two leaves
- 3 Place the nodes in water, damp sphagnum moss, or a mix with about one third perlite
- 4 Keep warm, humid and in bright indirect light
- 5 Pot up once roots are 2-3 cm long or new leaves appear
Materials needed:
Layering
Because the stems creep and root naturally, layering is almost foolproof.
- 1 Lay a trailing stem on the surface of a small pot of moist mix
- 2 Pin the nodes down so they touch the soil
- 3 Cut the stem from the mother plant once roots have formed

What Diseases Commonly Affect Tiny-leaf Porcelain Flower?
TLDR: Tiny-leaf Porcelain Flower is susceptible to 6 known diseases. Monitor regularly for early detection.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Mealybugs
Mealybugs are small, soft-bodied insects covered with a white, waxy, cottony material. They are common pests of houseplants and outdoor plants in mild climates. These sap-sucking insects feed on plant tissue, causing damage, stunted growth, and can lead to plant death if left untreated. They produce sticky honeydew which attracts sooty mold.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Fun Facts
Its leaves are only about 2 cm long, among the smallest in the genus.
In strong light the leaves turn reddish, a sign the plant is getting enough sun to flower.
In the wild it creeps over tree trunks as an epiphyte instead of growing in soil.
