Padang Sidempuan is a rare and recently discovered Hoya species from Padang Sidempuan, a tropical region in North Sumatra, Indonesia. Like many location-specific Hoyas, it remains undescribed botanically (sp. meaning species), but it is already highly sought after by collectors for its distinctive foliage and flowers.
This species produces thick, leathery, elongated oval leaves with a glossy surface and clear venation. The foliage is often dark green with subtle silver flecking, though under bright light, it may develop red or bronze tinges around the margins. Its leaves are moderately large and slightly convex, creating a lush, tropical look.
When mature, Hoya sp. Padang Sidempuan produces clusters (umbels) of waxy, star-shaped flowers. These blooms are creamy-white to pink with a darker pink corona and emit a sweet, strong fragrance, particularly noticeable in the evening. The combination of attractive leaves and perfumed blossoms makes it an outstanding species for collectors.
Thrives in bright, indirect light. Can tolerate some soft morning or late-afternoon sun. Insufficient light may reduce flowering, while intense direct sunlight can scorch the leaves.
Water when the top 23 cm of soil feels dry. As a semi-succulent, it prefers to dry out slightly between waterings. Avoid waterlogging. In winter, water less frequently.
Temperature: Prefers 1828C. Avoid temperatures below 15C.
Humidity: Enjoys high humidity (6080%). Average household humidity is tolerated, but higher levels encourage healthy growth and flowering.
Use a chunky, free-draining epiphytic mix a blend of orchid bark, perlite, coco husk, and a small amount of peat-free compost works well. Hoyas prefer being slightly root-bound, so repot every 23 years.
Feed monthly in spring and summer with a high-potassium fertiliser to promote flowering. Stop feeding in autumn and winter.
Prune to control size and encourage branching. Do not remove flower peduncles (spurs), as Hoyas rebloom from these year after year.
A moderate to fast grower that develops climbing or trailing vines up to 12 metres long indoors. Flowers usually appear on established plants once the root system is well developed.
No blooms: Insufficient light or premature removal of flower spurs.
Yellowing leaves: Overwatering or poor drainage.
Shrivelled leaves: Extended underwatering.
Pests: Occasionally mealybugs, aphids, or spider mites.
Named after the region of Padang Sidempuan in North Sumatra, this rare Hoya is still new to cultivation, making it a prized find for collectors. It combines the toughness of tropical Hoyas with the elegance of glossy foliage and sweetly fragrant blooms. Its locality origin adds to its uniqueness, appealing to enthusiasts who enjoy collecting Hoyas from specific regions.
