Columnea brenneri is an evergreen perennial native to the tropical rainforests of Ecuador. This species is characterised by its upright growth habit, with rigid, wood-like stems reaching heights of 30 to 60 centimetres. The leaves are glossy on the upper surface, deeply ribbed, and exhibit variations in colour on the underside, ranging from green with burgundy veins to entirely burgundy or green. The plant produces distinctive, fuzzy flowers approximately 4 centimetres in length, featuring yellow or chartreuse tubes adorned with burgundy markings. Following the flowering period, it develops unusual, pastel lavender fruits.

Native to:
Columnea brenneri originates from the tropical rainforests of Ecuador, where it thrives in humid, shaded environments.

Water:
Maintain consistently moist soil for Columnea brenneri, allowing the top third to dry out between waterings. Overwatering can lead to root rot; therefore, ensure the pot has adequate drainage to prevent waterlogging.

Light:
Provide bright, indirect light to mimic the plant's natural understory habitat. Direct sunlight can scorch the leaves, while insufficient light may hinder growth and flowering. A location near an east or north-facing window is ideal.

Humidity:
Columnea brenneri prefers high humidity levels, ideally above 50%. In the UK, indoor environments often have lower humidity, especially during winter months. To increase humidity, consider using a humidifier, placing the plant on a tray of moist pebbles, or regularly misting the leaves. Its preference for high humidity makes it suitable for terrarium cultivation, provided the plant's size allows.

Temperature:
This species thrives in temperatures between 18°C and 24°C. It is sensitive to cold drafts and temperatures below 10°C, which can cause stress and inhibit growth. Maintain a stable indoor temperature within this range to support healthy development.
