Mint Bush vs Moreton Bay Fig Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Mint Bush
Prostanthera rotundifolia
Prostanthera rotundifolia, commonly known as the Round-leaf Mint Bush, is an Australian native shrub prized for its aromatic foliage and profuse display of mauve to purple flowers. It typically grows to around 1-2 meters in height and width. The plant is naturally an outdoor plant, thriving in well-drained soils and full sun. People grow it for its ornamental value, attracting pollinators, and the pleasant minty fragrance released when the leaves are crushed. It is not typically grown indoors due to its high light requirements and size.
Moreton Bay Fig
Ficus macrophylla
The Moreton Bay Fig is a massive evergreen tree characterized by its impressive buttress roots and wide-spreading canopy. In its native habitat, it can reach heights of over 60 meters. It is primarily an outdoor tree, valued for its shade and dramatic presence. It is not naturally an indoor plant, and maintaining it indoors long-term is challenging due to its size and light requirements. People grow it outdoors for its ornamental value and shade.

❓ Frequently Asked Questions — Comparing These Plants
Mint Bush
What are the light requirements for Mint Bush?
Mint Bush requires bright, indirect light to thrive. An east-facing window is ideal, providing gentle morning sun. A west-facing window can also work, but shield the plant from intense afternoon sun. Insufficient light will result in leggy growth and reduced flowering. South-facing windows may be too intense, requiring sheer curtains to diffuse the light.
How do I care for Mint Bush?
Mint Bush thrives in bright, indirect light; direct sunlight can scorch its leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain moderate humidity levels, especially during drier months. Fertilize regularly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength, to encourage blooming.
How do I propagate Mint Bush?
Mint Bush can be propagated through stem cuttings. Take 4-6 inch cuttings from healthy stems, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil consistently moist and provide bright, indirect light. Roots should develop in a few weeks.
Moreton Bay Fig
What are the light requirements for Moreton Bay Fig?
Moreton Bay Figs require bright, indirect light to thrive indoors. Placing them near a large east- or west-facing window is ideal, providing ample light without direct sun exposure. A south-facing window can also work, but it’s important to filter the light with a sheer curtain to prevent leaf burn. Insufficient light can lead to leggy growth and leaf drop. Rotate the plant regularly to ensure all sides receive adequate light. If natural light is limited, consider supplementing with a grow light. The light should be consistent.
How do I care for Moreton Bay Fig?
The Moreton Bay Fig thrives in bright, indirect light; avoid direct sunlight which can scorch the leaves. Water thoroughly when the top inch of soil is dry, allowing excess water to drain away. Overwatering can lead to root rot, so ensure the pot has drainage holes. Maintain a consistent temperature between 65-75°F (18-24°C) and avoid sudden temperature fluctuations. These plants appreciate humidity; mist the leaves regularly or use a humidifier. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Prune occasionally to maintain shape and remove any dead or damaged branches. Repot every 2-3 years into a slightly larger pot with well-draining potting mix. Rotate the plant regularly to ensure even growth on all sides. Keep the pot clean.
How do I propagate Moreton Bay Fig?
Moreton Bay Figs can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in moist potting mix and cover with a plastic bag to maintain humidity. Keep in a warm, bright location until roots develop. For air layering, make a small cut on a stem, wrap it with moist sphagnum moss, and cover with plastic wrap. Once roots develop, cut the stem below the roots and plant in potting mix. Propagation is best done in the spring or summer. Always use clean tools. Patience is key.
