Cup and Saucer Vine vs Rabbit Foot Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Cup and Saucer Vine
Cobaea scandens
Cobaea scandens, commonly known as the Cup and Saucer Vine, is a vigorous, fast-growing perennial climber typically grown as an annual in temperate climates. It features distinctive cup-shaped flowers (the 'cup') sitting atop a saucer-like calyx. The flowers start as greenish-white and mature to a rich purple, attracting pollinators like bees and hummingbirds. It's primarily an outdoor plant, prized for its rapid growth and ability to cover fences, walls, and trellises quickly. While some attempt to grow it indoors, it requires very bright light and significant space, making it challenging.
Rabbit Foot Fern
Davallia fejeensis
The Rabbit's Foot Fern is an epiphytic fern characterized by its furry, creeping rhizomes that resemble rabbit's feet. These rhizomes grow over the edge of the pot, adding a unique textural element. The fronds are finely divided and lacy, creating a delicate, airy appearance. While it can be grown indoors, it thrives best in humid environments. People grow it for its unusual rhizomes and attractive foliage, making it a conversation piece.

Rabbit Foot Fern
What are the light requirements for Rabbit Foot Fern?
Rabbit Foot Ferns prefer bright, indirect light. Avoid direct sunlight, as it can scorch the delicate fronds. An east-facing window is ideal, providing gentle morning light. A north-facing window can also work, though growth may be slower. If you only have south or west-facing windows, place the fern further away from the window or use a sheer curtain to filter the light. Insufficient light can lead to leggy growth and pale fronds. Rotate the plant regularly to ensure even light exposure on all sides. Monitor the fronds for signs of sunburn, such as browning or crisping, and adjust the plant’s location accordingly.
How do I care for Rabbit Foot Fern?
Rabbit Foot Ferns thrive in bright, indirect light and require consistently moist soil. Water when the top inch of soil feels dry, ensuring proper drainage to prevent root rot.
