Hoya sp. Rangsan 'Large Leaf' – Broad-Leaved Climber for Indoors

Hoya sp. Rangsan 'Large Leaf' is an impressive, unidentified clone collected from the Rangsan region in Thailand. Known for its broad, semi-succulent leaves and sturdy vining habit, this rare tropical plant is a must-have for collectors. The deep green foliage, often speckled under bright light, turns this vining beauty into a statement piece in any space. While not yet formally described in botanical literature, its popularity among Hoya enthusiasts continues to grow.
Thick Foliage, Steady Climber
 
Leaf shape: Broad and oval with a leathery, semi-gloss texture
 
Size: Leaves reach 10–15 cm in length under good indoor conditions
 
Growth style: Twining vines suitable for hanging pots, trellises, or hoops
 
Light speckling: More visible under bright, indirect light
 
Indoor spread: Vines can grow over 1 m with time and support
Natural Habitat and Botanical Context
This form originates from tropical lowlands in Rangsan, Thailand, where it climbs among forest edges in dappled light and high humidity. The thick foliage indicates an adaptation to fluctuating moisture conditions. Though still taxonomically unresolved, its striking appearance has made it a sought-after cultivar. The term “sp.” reflects its undescribed status. “Large Leaf” distinguishes this form from narrower-leaved variants in the same collection region.
Note: No confirmed data exists on floral traits. Any bloom behavior should be considered anecdotal.
Care Guide for Hoya sp. Rangsan 'Large Leaf'
 
Light: Bright, indirect light promotes thicker foliage; tolerates early morning sun
 
Watering: Let the top half of the substrate dry before watering again
 
Humidity: Best at 60–80%; occasional misting or grouping with other plants helps
 
Temperature: Performs best at 20–28 °C; protect from drafts
 
Soil mix: Use orchid bark, perlite, and coco coir for optimal drainage
 
Fertiliser: Apply monthly with diluted liquid feed during active growth
 
Repotting: Every 2–3 years; flowering is more likely when slightly rootbound
 
Propagation: Root cuttings with at least one node in water or airy substrate
 
Hydroponic compatibility: Grows well in semi-hydro with stable warmth and airflow
Troubleshooting Common Issues
 
Wrinkled leaves: A sign of dehydration — water more consistently
 
Yellowing lower leaves: Usually caused by overwatering or soggy substrate
 
Lack of flowering: Plant may need more time, light, or stable conditions
 
Spider mites/mealybugs: Spot treat with neem oil or insecticidal soap
 
Fungus gnats: Let the upper soil dry more between waterings
Real-World Growing Tips
 
Train on a trellis or allow to cascade naturally for visual impact
 
Keep peduncles intact if flowers appear — Hoyas may rebloom from the same spot
 
Good airflow reduces fungal risks and supports healthy growth
Etymology and Taxonomic Status
Hoya is named after Thomas Hoy, a botanist known for cultivating tropical species in 18th-century England. As this form is still undescribed, “sp.” denotes its unknown species identity, and “Rangsan” refers to its geographic origin. The nickname “Large Leaf” highlights its most distinctive feature compared to other clones.
