Arum vs Lantana 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.
Lantana
Lantana camara
Lantana camara is a sprawling shrub typically grown outdoors, known for its clusters of small, brightly colored flowers that bloom almost continuously in warm weather. The flower colors can vary within the same cluster, often displaying shades of yellow, orange, red, pink, and white. It is a vigorous grower and can become quite large if not pruned. While prized for its vibrant blooms and ability to attract pollinators, it is considered invasive in many regions due to its rapid spread and adaptability. It is primarily an outdoor plant and struggles indoors due to high light requirements.

❓ 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).
Lantana
What are the light requirements for Lantana?
Lantana requires abundant sunlight to thrive and produce its characteristic vibrant blooms. Ideally, it should receive at least 6-8 hours of direct sunlight each day. Insufficient light can result in leggy growth, reduced flowering, and dull foliage. When grown indoors, place Lantana near a south-facing window where it can receive maximum light exposure. If natural light is limited, supplement with artificial grow lights. Rotate the plant regularly to ensure even light distribution and prevent it from leaning towards the light source. In outdoor settings, choose a location that is fully exposed to the sun for most of the day. Avoid planting Lantana in shady areas or under trees, as this will hinder its growth and flowering potential.
How do I care for Lantana?
Lantana thrives in full sun, requiring at least 6-8 hours of direct sunlight per day. Water thoroughly when the top inch of soil feels dry, allowing excess water to drain away. Avoid overwatering, as this can lead to root rot. Fertilize monthly during the growing season (spring-fall) with a balanced fertilizer formulated for flowering plants, following package instructions. Prune regularly to encourage bushier growth and more abundant blooms, removing spent flowers and any dead or diseased branches. Lantana prefers well-draining soil with a slightly acidic to neutral pH. Provide good air circulation to prevent fungal diseases. Protect from frost in colder climates, either by bringing potted plants indoors or covering them with frost blankets. Monitor for pests such as aphids and whiteflies, and treat promptly with insecticidal soap or neem oil.
How do I propagate Lantana?
Lantana can be easily propagated through stem cuttings. Take a 4-6 inch cutting from a healthy stem, removing the lower leaves. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and place the cutting in a warm, bright location. Roots should develop within a few weeks. Division is possible for established plants. Carefully dig up the plant and separate the root ball into smaller sections, each with healthy roots and stems. Replant the divisions in separate pots or in the ground. Keiki propagation is not applicable to Lantana.
