Ficus altissima, often referred to as the Council Tree, is a striking indoor tree known for its glossy green leaves splashed with vibrant lime to yellow variegation.

A member of the Ficus family, it offers a brighter, more tropical alternative to the classic Fiddle Leaf Fig. Its oval leaves feature a bold central vein with marbled chartreuse patterns that intensify in bright light.

With its upright growth and tree-like structure, Ficus altissima makes an excellent statement plant for living rooms, offices and open-plan spaces.

Care Guide

Light

Bright, indirect light is essential.

• Thrives near south- or west-facing windows (with light filtering if needed)

• Tolerates bright indirect light very well

• Too little light may reduce variegation

The brighter the light, the more vibrant the yellow tones become.

---

Watering

Allow the top 3–5cm of soil to dry before watering.

• Spring/Summer: Water thoroughly when slightly dry

• Autumn/Winter: Reduce frequency

Important:

• Use a pot with drainage holes

• Avoid leaving roots sitting in water

Overwatering is the most common issue with Ficus plants.

---

Humidity

Prefers moderate humidity.

• Ideal range: 50–60%

• Adapts well to average UK home conditions

• Benefits from occasional misting

Very dry air may cause leaf drop or browning edges.

---

Temperature

• Ideal: 18–26°C

• Avoid temperatures below 15°C

• Keep away from cold draughts

Ficus plants prefer stable environments and dislike sudden changes.

---

Soil & Potting Mix

Use a well-draining mix:

• Peat-free houseplant compost

• Perlite

• A small amount of bark for aeration

Good drainage is essential to prevent root rot.

---

Feeding

Feed during active growth (March–September):

• Balanced liquid fertiliser every 3–4 weeks

• Reduce or stop feeding in winter

Avoid overfeeding to prevent leaf burn.

---

Growth Habit

• Upright, tree-form structure

• Can reach 1.5–2 metres indoors with time

• Produces new growth from the tips

Prune lightly to maintain shape and encourage bushier growth.

---

Common Problems

Leaf drop

• Environmental stress

• Sudden temperature changes

Yellowing leaves

• Overwatering

Loss of variegation

• Insufficient light

Brown edges

• Dry air

Ficus plants may shed a few leaves when adjusting to a new environment.

Styling Ideas

• Ideal as a focal floor plant

• Works beautifully in modern, bright interiors

• Pairs well with darker foliage plants for contrast

• Looks striking in neutral or woven baskets

Its vibrant variegation brings warmth and tropical energy to larger spaces.
