Cranberry vs Peacock Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Cranberry
Vaccinium macrocarpon
Vaccinium macrocarpon, commonly known as cranberry, is a low-growing, trailing shrub or vine. It's a perennial plant native to North America. It features small, evergreen leaves and produces tart, red berries that are commercially grown, especially in bogs. Cranberries are primarily grown for their fruit, which is used in juices, sauces, and dried snacks. The plant itself is not typically grown indoors due to its specific environmental requirements, including acidic soil, high moisture, and a period of cold dormancy.
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.

💧 Watering Needs
Cranberry
Cranberries require consistently moist, acidic soil. Water deeply when the top inch of soil feels dry. Avoid overwatering, which can lead to root rot. Ensure good drainage. If grown in a container, monitor moisture levels carefully, as containers dry out faster than soil in the ground. Rainwater is preferred due to its acidity.
Peacock Fern
Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels slightly dry. Overwatering can lead to root rot, while underwatering will cause the fronds to dry out and turn brown. Use distilled or rainwater to avoid mineral buildup.

❓ Frequently Asked Questions — Comparing These Plants
Cranberry
What are the light requirements for Cranberry?
Cranberries thrive in bright, indirect light. Direct sunlight can scorch the leaves, especially indoors. An east-facing window is often ideal, providing gentle morning sun. A south- or west-facing window can also work, but you may need to filter the light with a sheer curtain to prevent leaf burn. Insufficient light can lead to leggy growth, poor flowering, and reduced berry production.
How do I care for Cranberry?
Cranberries need acidic soil with a pH between 4.5 and 5.5. Plant in a well-draining mix of peat moss, sand, and perlite. Water deeply when the top inch of soil feels dry, using rainwater or distilled water to avoid alkaline tap water. Provide bright, indirect light for optimal growth and berry production. Fertilize sparingly with an acid-loving fertilizer during the growing season (spring and summer).
How do I propagate Cranberry?
Cranberries can be propagated by stem cuttings, division, or 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 moist, acidic potting mix. Cover with a plastic bag to maintain humidity and keep in bright, indirect light. Roots should develop in 4-6 weeks.
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.
