Compare these two plants side by side — care needs, key differences, and which is right for your home.
Arum
Arum italicum
Arum italicum is a tuberous herbaceous perennial known for its striking foliage and distinctive spadix and spathe flower structure. It emerges in the fall with arrow-shaped leaves, often beautifully veined in white or cream. The plant goes dormant in the summer. It is primarily an outdoor plant, thriving in woodland conditions. While it can be grown indoors, it requires very specific conditions to mimic its natural habitat. People grow it for its attractive foliage and unique flower structure.
Pachira Aquatica
Pachira aquatica
Pachira aquatica, commonly known as the Money Tree, is a tropical wetland tree that can grow up to 60 feet tall in its native habitat. It's often grown indoors as a smaller, more manageable plant, typically featuring a braided trunk formed by several young trees. The plant has palmate leaves with 5-9 leaflets. It's believed to bring good luck and prosperity, making it a popular choice for homes and offices. While it can flower and produce fruit in the wild, this is rare for indoor specimens.

❓ Frequently Asked Questions — Comparing These Plants
Arum
What are the light requirements for Arum?
Arum plants thrive best in bright, indirect light. Direct sunlight can scorch the leaves, so avoid placing them in areas with intense midday sun. An east-facing window is often ideal, providing gentle morning light. If you only have south or west-facing windows, filter the light with sheer curtains or blinds. Insufficient light can result in leggy growth and reduced flowering. Rotate the plant regularly to ensure even light exposure on all sides. During the darker months, consider supplementing with artificial grow lights to maintain healthy growth. Observe the plant’s foliage; if the leaves appear pale or stretched, it’s a sign that it needs more light.
How do I care for Arum?
Arum plants prefer bright, indirect light but can tolerate some shade. Water thoroughly when the top inch of soil feels dry to the touch, ensuring good drainage to prevent root rot. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Reduce watering and fertilization during the dormant period in fall and winter. Maintain moderate humidity, especially indoors. Repot every 1-2 years in spring, using a well-draining potting mix. Prune away any yellowing or dead leaves to encourage healthy growth. Protect from frost as Arum is not cold hardy. Monitor for pests such as aphids or spider mites and treat accordingly. Proper air circulation is essential to prevent fungal diseases.
How do I propagate Arum?
Arum can be propagated through division, stem cuttings, or from bulb offsets (keikis).
Pachira Aquatica
What are the light requirements for Pachira Aquatica?
Pachira Aquatica prefers bright, indirect light. Direct sunlight can burn its leaves, so avoid placing it in a south-facing window without any protection. An east- or west-facing window is ideal, or a few feet back from a south-facing window. If you notice the leaves becoming pale or yellow, it may be receiving too much direct light. Conversely, if the plant’s growth is slow and the leaves are small, it may not be getting enough light. Rotate the plant regularly to ensure all sides receive adequate light. Artificial grow lights can supplement natural light, especially during winter months.
How do I care for Pachira Aquatica?
Pachira Aquatica thrives with bright, indirect light. Avoid direct sunlight, which can scorch the leaves. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain. Overwatering is a common problem, so ensure proper drainage. Maintain a humidity level of 40-60%. Use a well-draining potting mix. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot every 2-3 years, or when the plant becomes root-bound, into a slightly larger pot. Prune regularly to maintain shape and remove any dead or yellowing leaves. Keep the plant away from cold drafts and sudden temperature changes. Rotate the plant periodically to ensure even growth.
How do I propagate Pachira Aquatica?
Pachira Aquatica 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 a well-draining potting mix and keep it moist. Cover with a plastic bag to increase humidity. Rooting typically takes several weeks. For air layering, make a small cut on a stem and wrap it with moist sphagnum moss. Cover the moss with plastic wrap and secure it with tape. Once roots appear, cut the stem below the roots and plant it in a pot. Maintain consistent moisture and humidity during the propagation process. Provide bright, indirect light.
