Hoya (Wax Plants & Porcelain Flowers)

Hoya is an enchanting genus of semi-epiphytic, succulent climbing vines famous for thick waxy leaves and intensely fragrant porcelain star-shaped flower umbels. Entirely non-toxic to cats and dogs, Hoyas thrive in bright indirect light with gentle morning sun and chunky, breathable epiphytic substrates.

🌸 Golden Rule of Hoya Flowers:

Hoyas bloom from perennial woody spurs called peduncles. Never cut off the peduncles after the flowers fade! The plant will re-bloom from the exact same spurs year after year.

Light Exposure

Bright indirect to dappled morning sun (400–1,000+ fc) essential for flowering umbel formation.

Watering Physics

Drought-tolerant. Allow mix to dry nearly 100% before drenching. Perform the leaf taco test for softness.

Substrate Blend

Chunky epiphytic mix: 40% coarse orchid bark, 30% perlite/pumice, 20% coco husk, 10% potting soil.

Flower Preservation

Never prune off peduncle spurs! Keep pot-bound in snug planters to stimulate blooming cycles.
