Hoya 'Sunrise'

Hoya ‘Sunrise’

Hoya ‘Sunrise’ is a compact trailing Hoya hybrid with small leathery leaves, clear venation and colour that can shift from green into red, amber or bronze in bright filtered light. It is a documented F1 hybrid from Hoya lacunosa × Hoya obscura, created by Michael Miyashiro.

The plant naturally forms pendant or creeping stems with flexible growth suited to hanging pots and mounted setups. In a hanging pot it can build a full canopy over time, while mature plants may produce clusters of small waxy flowers from persistent peduncles.

Veined leaves from Hoya lacunosa × Hoya obscura

• Documented F1 hybrid from Hoya lacunosa × Hoya obscura.
• Small leathery leaves show clear venation and warm light-responsive colour.
• Pendant stems suit hanging pots, shelves and mounted growing.
• Compact growth keeps the plant manageable on shelves, hangers and mounted setups.
• Mature plants can flower from peduncles that remain active over time.

Origin of the Hoya ‘Sunrise’ hybrid

Hoya ‘Sunrise’ was selected from F1 hybrids made by hand-pollinating Hoya lacunosa with Hoya obscura. The cross was made by Michael Miyashiro in 1992, and the cultivar was named and published 12 years later, with Carol Noel recorded as nominant.

Hoya lacunosa is native from southern Myanmar to western and central Malesia, while Hoya obscura subsp. obscura is recorded from Borneo to the Philippines. Both are climbing epiphytes or lithophytes, which explains why Hoya ‘Sunrise’ responds best to warm conditions, bright filtered light and a potting mix that does not collapse around the roots.

Keeping Hoya ‘Sunrise’ compact and colourful

• Light: Place in very bright indirect light; introduce gentle direct sun gradually to avoid marking the leaves.
• Watering: Water deeply once the upper mix has dried, then allow excess water to drain away.
• Substrate: Use bark, perlite, pumice or coco chips so moisture drains while roots stay aerated.
• Humidity: Moderate to high humidity reduces dry tips on pendant growth, especially in hanging or mounted setups.
• Temperature: Keep around 18–28°C and move away from cold glass during winter nights.
• Feeding: Feed lightly during active growth, then reduce feeding when light and growth slow.
• Placement: Rotate the pot occasionally so trailing stems develop evenly around the container.
• Peduncles: Keep old flowering spurs because repeat blooms can form from the same points.

Leaf curl, colour changes and bud drop

• Curled leaves: Check for dry roots, intense sun or pest activity before changing the watering pattern.
• Weak green growth: Increase bright filtered light gradually and check that temperatures stay warm enough.
• Brown dry patches: Reduce direct sun and check whether leaves are touching hot or cold glass.
• Bud drop: Keep watering and placement consistent while buds are forming.
• Yellowing at the base: Inspect roots and refresh heavy substrate if the mix remains wet for several days.

Handling Hoya ‘Sunrise’ safely

Hoya ‘Sunrise’ is an ornamental Hoya. Keep vines, flowers and pruned stems away from pets and children that chew plants, and rinse skin after contact with fresh sap if irritation occurs.

Hybrid background of Hoya ‘Sunrise’

Hoya is a genus in the Apocynaceae family and honours Thomas Hoy. Hoya ‘Sunrise’ has documented hybrid parentage from Hoya lacunosa × Hoya obscura, with Michael Miyashiro recorded as the originator and Carol Noel connected with its 2004 publication.

Hoya ‘Sunrise’ develops pendant stems with veined leaves that can turn amber, red or bronze as they mature in bright filtered light.
