Ficus elastica 'Robusta' - Rubber Plant

Why the Ficus elastica 'Robusta' makes a great office plant

There is something undeniably charismatic about the Ficus elastica ‘Robusta’. With leaves that gleam like polished leather and a stature that conveys calm confidence, this plant carries the spirit of tropical rainforests straight into contemporary workplaces. Its broad, dark green foliage sits on a sturdy trunk, creating a sculptural silhouette that feels both modern and timeless. The subtle red tint along emerging leaves adds a touch of drama, almost as if the plant is quietly rehearsing for a close-up.

In office environments, this species has become something of a classic. Its generous size makes it a compelling visual anchor, perfect for softening architectural lines or acting as a discreet room divider. At 170 centimetres tall and 70 centimetres wide, it has enough presence to elevate reception areas, meeting rooms, or collaborative zones without overwhelming the space.

One of the reasons the Ficus elastica ‘Robusta’ fits so naturally into offices is its affinity for stable indoor conditions. It adapts gracefully to typical workplace temperatures and thrives in light levels that are common near desks, corridors, or open-plan layouts. It grows quietly, without producing pollen, making it a low-disruption botanical companion in busy work areas. Its evergreen character ensures year-round visual consistency, providing a steady backdrop of lush greenery that enhances focus and atmosphere.

Under what conditions does the Ficus elastica 'Robusta' thrive?

The Ficus elastica ‘Robusta’ traces its origins to the tropical rainforests of Southeast Asia, where humidity wraps around towering canopy trees and sunlight filters through layers of leaves. Indoors, this heritage expresses itself in the plant’s preference for light to semi-shady positions. A warm environment and a touch of humidity reflect its natural climate, supporting consistent growth and that signature glossy leaf sheen.

Maintenance

Watering

The plant should be watered with moderation, reflecting its sensitivity to standing water. It should be ensured that the substrate dries slightly between water cycles, particularly during the darker winter months when its natural growth slows.

Fertilizing

The plant should be fertilized in intervals that support steady development throughout the brighter seasons. It should be ensured that nutrient levels remain balanced to maintain strong leaf colour and trunk stability.

Cutting

Cutting can be performed to guide its shape or maintain suitable office dimensions. It should be ensured that pruning supports healthy branching while retaining the plant’s robust posture.

Other Care

Other care steps include periodic repotting, ideally undertaken in spring to accommodate root expansion. It should be ensured that temperatures remain warm and drafts are avoided to protect the plant’s tropical character.

All of these steps are seamlessly managed through Oxygen at Work’s all-inclusive maintenance package, ensuring each plant receives professional horticultural attention while clients enjoy the results without handling care themselves.

How much water is evaporated by the Ficus elastica 'Robusta'?

George, Data Project Manager

“Using research, real-life tests, and office air quality data, we approximate the effect of different plant species. Of course, the actual effect can vary depending on things like room conditions and the plant’s overall health.”

The Ficus elastica ‘Robusta’ demonstrates a balanced and efficient contribution to indoor environments. With a height of 170 centimetres, a width of 70 centimetres, and a total leaf surface of 1.107 square metres, it releases approximately 1.9 litres of water vapour per month. This subtle but steady evaporation supports indoor humidity levels in a gentle, natural way. For context, a larger Howea forsteriana with a height of 1.90 metres and 0.7 metres in width evaporates around 2.1 litres monthly, showing how the Ficus elastica ‘Robusta’ offers comparable benefits despite its more compact architecture.
