Large-Flowered Copper-Striped Cambria Orchid (Odontoglossum-Type)

Large, painterly blooms in warm copper tones with intricate striping make this Cambria Orchid a true statement plant. These orchids belong to the Oncidium alliance and were historically grouped under Odontoglossum, a genus prized for its cool-growing mountain species. Their dramatic flowers can last for many weeks, making them a long-lasting and rewarding houseplant.

Scientific Name
Oncidium Alliance Hybrid (massed like a little swelling, referring to the bulb-like growths)

Many plants previously sold as Odontoglossum were reclassified into Oncidium following taxonomic revisions in the early 2000s.

Synonyms
Formerly sold as Odontoglossum hybrids

Often labelled in the trade as “Cambria”

Common Name
Cambria Orchid, Odontoglossum-Type Orchid

Origin
Hybrid orchids derived from species native to the cloud forests of Central and South America, particularly Colombia and Ecuador.

Light
Bright, indirect light is ideal. A position near an east or north-facing window works well. Avoid strong midday sun, which can scorch the leaves. If leaves become very dark green, the plant may need slightly more light.

Water
Water thoroughly when the top half of the potting mix feels dry. These orchids prefer to dry slightly between waterings but should not remain bone dry for long periods. Reduce watering in winter when growth slows. Never allow the pot to sit in water.

Humidity
Prefers moderate humidity. A pebble tray with water underneath the pot can help in drier homes, especially during winter heating season. Avoid misting directly into the centre of the plant.

Soil
Use a specialist orchid bark mix that allows plenty of airflow around the roots. Repot every 2–3 years after flowering, or when the bark begins to break down.

Food
Feed with a balanced orchid fertiliser every 2–3 waters during the growing season. Reduce feeding in winter.

Temperature
Prefers cooler household temperatures between 16–22°C. Avoid placing near radiators or cold draughts.

Pet-safe
Generally considered non-toxic, but not intended for consumption.

Sprouts Top Tips
After flowering, cut the spent spike back to the base and continue caring for the plant as normal. With good light and steady care, new growth will develop from the base and produce the next flower spike.

Extras
Unlike moth orchids, Cambrias produce pseudobulbs – small swollen growths at the base of the leaves that store water and energy.

Did You Know?
Odontoglossum means “tooth tongue” in Greek, referring to the tooth-like callus found on the lip of the original species.
