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.

Peacock Fern

Peacock Fern

Selaginella willdenowii

Selaginella willdenowii, commonly known as Peacock Fern, is a fern ally prized for its iridescent blue-green foliage. This plant is not a true fern but a spikemoss. The shimmering effect is caused by structural coloration, where light reflects off the leaf surface. It thrives in humid, shaded environments, mimicking its native rainforest habitat. While it can be grown indoors, maintaining the necessary humidity is crucial for its survival. People grow it for its unique and captivating foliage, adding a touch of exotic beauty to indoor spaces or terrariums. It is primarily an outdoor plant in tropical climates.

❓ 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.

Peacock Fern

What are the light requirements for Peacock Fern?

Peacock Fern requires bright, indirect light to maintain its vibrant color. Direct sunlight can burn its delicate fronds, causing them to turn brown and crispy. An east-facing window is ideal, providing gentle morning light. If placing it near a south- or west-facing window, use a sheer curtain to filter the light.

How do I care for Peacock Fern?

Peacock Fern thrives in bright, indirect light. Direct sunlight can scorch its delicate fronds. Maintain consistently moist soil, but avoid waterlogging. Water when the top inch of soil feels slightly dry. High humidity is crucial; aim for 60-80%. Use a humidifier, pebble tray, or group plants together to increase humidity.

How do I propagate Peacock Fern?

Peacock Fern can be propagated through division or by spores. Division is the easier method. In spring, gently remove the plant from its pot and carefully separate the root ball into smaller sections, ensuring each section has healthy fronds and roots. Plant each section in its own pot with well-draining soil. Keep the soil consistently moist and provide high humidity.
