Hoya blashernaezii – Rare Philippine Species for Collectors
Native to Catanduanes Island in the Philippines, Hoya blashernaezii is a striking vining species named in honor of Blas Hernaez, a key figure in Philippine Hoya research. Formally registered by Kloppenburg in 1999, this plant is prized for its slender, lance-like leaves and abundant floral clusters. Leaves typically measure 7–12 cm long and 2–3 cm wide, tapering to a fine point with a rounded base. In bloom, expect elegant umbels of 20–30 bell-shaped flowers, creamy yellow with delicate red pedicels, lasting about a week. While the fragrance is faint, the display is showy and frequent in warm, bright indoor conditions. Adaptable and forgiving, this species tolerates temperatures from 15–35 °C, making it suitable for a wide range of interiors.
What Makes Hoya blashernaezii Special

  
Leaf Shape: Narrow, pointed leaves with clear midvein
  
Flower Display: Cream-yellow bells, up to 30 per umbel
  
Growth Form: Flexible climbing or trailing vines
  
Blooming Period: Summer indoors, year-round in natural habitat
  
Propagation: Easy from cuttings; roots readily in water or semi-hydro
  
Temperature Range: Thrives in 15–35 °C indoors

Natural Background & Growth Behavior
Found in tropical lowland forests of Catanduanes, this Hoya grows as an epiphyte, clinging to tree branches in humid, filtered light conditions. With rainfall exceeding 2,500 mm annually and constant warmth, it is adapted to airy, moisture-retentive environments. Indoors, expect moderate to fast growth and vines reaching 1–2 m with time. Like other Hoyas, its sap is mildly toxic if ingested, so keep out of reach of pets and small children.
