Arum vs Mole Plant Plant Comparison
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.
Mole Plant
Araujia sericifera
Araujia sericifera, commonly known as Mole Plant or Cruel Plant, is a vigorous, twining vine that can grow up to 5-7 meters in length. It's an aggressive climber, often found smothering other vegetation. The plant produces attractive, fragrant, trumpet-shaped flowers, typically white or pale pink with purple tinges. These flowers attract moths and other insects, which can become trapped in the flower's intricate structure, hence the name 'Cruel Plant'. It is primarily an outdoor plant and not suited for indoor cultivation due to its size and invasive nature. People may grow it for its interesting flowers, but its invasive potential makes it a problematic choice.

❓ 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).
Mole Plant
What are the light requirements for Mole Plant?
Mole Plant thrives best in full sun, requiring at least 6-8 hours of direct sunlight per day. However, it can tolerate partial shade, especially in hotter climates where intense afternoon sun can scorch the leaves. When grown indoors, place it near a south-facing window to maximize light exposure. Rotate the plant regularly to ensure even growth. Insufficient light can lead to leggy growth and reduced flowering. Supplement with grow lights if natural light is limited, especially during winter months. Monitor the plant for signs of stress, such as pale leaves or stunted growth, which may indicate insufficient light.
How do I care for Mole Plant?
Mole Plant thrives in well-draining soil and prefers full sun to partial shade. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Fertilize sparingly, using a balanced liquid fertilizer diluted to half strength during the growing season (spring and summer). Avoid over-fertilizing, which can harm the plant. Provide adequate air circulation to prevent fungal diseases. Prune to remove dead or damaged foliage and to maintain desired shape. Protect from frost and freezing temperatures. Repot when the plant becomes root-bound, usually every 1-2 years. Monitor for pests such as aphids and spider mites, and treat promptly if detected. Remember that Mole Plant is toxic and should be kept away from children and pets.
How do I propagate Mole Plant?
Mole Plant can be propagated through seeds. Collect seeds from dried flower heads. Sow seeds in well-draining soil in spring. Keep soil moist and provide bright, indirect light. Seedlings should emerge in a few weeks. Once large enough to handle, transplant into individual pots. Alternatively, stem cuttings can be taken in spring or summer. Allow the cut end to callous over for a few days before planting in well-draining soil. Keep the soil moist and provide bright, indirect light. Rooting should occur in a few weeks. Division is not generally recommended for Euphorbia lathyris.
