Hoya latifolia ‘Silver’

Where the species behind Hoya latifolia ‘Silver’ grows naturally

Hoya latifolia is a large epiphytic or lithophytic climber native from Myanmar through western Malesia.

Care for Hoya latifolia ‘Silver’

• Support: Give the climbing stems a sturdy trellis or hoop with enough room for the broad leaves to expand freely.
• Light around the foliage: Bright diffuse light from an east- or west-facing window supports compact growth. Filter hot midday sun from the broad silvered foliage.
• Temperature: Keep the plant in the 16–24 °C range. Place it where temperatures do not linger below 10 °C.
• Root care and humidity: Use an evenly warm position while new growth is developing. Keep the surrounding air in the 50–60% range, with gentle airflow around the foliage.
• Watering: Rewater after the surface and upper layer have dried while deeper mix still holds a little moisture. Wet the root ball thoroughly and let excess water drain.
• Potting mix: A bark-led mix with coarse mineral material keeps the root zone open and well drained. The mix around Hoya latifolia ‘Silver’ should drain excess water quickly while retaining a small moisture buffer around the roots.
• Feeding: During active growth, use orchid fertiliser sparingly and taper feeding when new leaves or stems stop advancing.
• Silver pattern and new leaves: The broad leaves combine large silver areas with green veins and green patches. Give soft new leaves enough space to prevent contact marks.
• Repotting: Look at the root ball when it fills the container; degraded or slow-draining mix is another reason to refresh it. Refresh tired mix in the existing pot while the root ball still fits; choose the next pot size only for a genuinely crowded root system.
• Propagation: Choose a vigorous stem section with a node for propagation.

Common issues with Hoya latifolia ‘Silver’

• A large silver leaf develops a dark rub mark: Contact with the support occurred before the leaf stalk hardened. Upgrade to a rigid broad frame and secure the stem between leaves, leaving the leaf stalk and young blade free. Retain a firm bend; prune the section only if the stem splits or begins to decay.
• Black specks and scratches appear on a new silver leaf: The next leaf is being damaged by mites or thrips before expansion. Separate the plant and wash the affected growth. Apply insecticidal soap to all leaf surfaces as directed, including the nodes and undersides. Check the nodes and leaf undersides after treatment, then repeat only as the product label permits.
• A new silver-marked leaf hardens partly folded and undersized: The tip is being constrained before it can unfold. Shift the runner into open space and secure only the stem below the next node. Retain all sound tip tissue and remove only parts that have died or softened.
• Brown edges appear on broad leaves after repeated feeding: Dissolved salts have built up around roots in a slowly drying pot. Flush the mix with plenty of plain water and discard all runoff. Skip the next feeding and return at a lower concentration when new growth begins.

Hoya latifolia ‘Silver’ is non-toxic to people and pets

• This plant is non-toxic to people, cats and dogs.
• Chewing a large amount can still cause an upset stomach.
• If a large amount is eaten and symptoms continue, contact a veterinarian or medical professional.

How the name Hoya latifolia came about

Hoya honours the English gardener Thomas Hoy. Latifolia combines Latin latus, broad, with folium, leaf, and describes the species’ broad leaf blades.

Robert Brown established the genus Hoya in 1810 in Prodromus Florae Novae Hollandiae, page 459.

George Don first described Hoya latifolia in 1837 in A General History of the Dichlamydeous Plants, volume 4, page 127.
