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

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.

Night Phlox

What are the light requirements for Night Phlox?

Night Phlox thrives best in full sun, requiring at least 6 hours of direct sunlight per day. However, it can also tolerate partial shade, especially in hotter climates where intense afternoon sun can scorch the leaves. Insufficient light will result in fewer blooms and a weaker fragrance.

How do I care for Night Phlox?

Night Phlox thrives in well-draining soil and prefers full sun to partial shade. Water regularly, allowing the soil to dry slightly between waterings. Avoid overwatering, as this can lead to root rot. Fertilize every 2-4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer to promote blooming.

How do I propagate Night Phlox?

Night Phlox is typically propagated by seed. Sow seeds indoors 6-8 weeks before the last frost. Keep soil moist and warm until germination. Transplant seedlings outdoors after the last frost.
