Cup Flower vs Rabbit's Foot Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Cup Flower
Cobaea scandens
Cobaea scandens, commonly known as Cup Flower or Cup-and-Saucer Vine, is a vigorous, fast-growing perennial vine often grown as an annual in temperate climates. It is characterized by its climbing habit, using tendrils to attach to supports. The plant produces unique, bell-shaped flowers that start green and mature to a deep purple or white, resembling cups sitting on saucers. It is primarily an outdoor plant, valued for its rapid growth and ability to cover fences, trellises, and walls quickly. While occasionally grown indoors, it requires significant space and light to thrive.
Rabbit's Foot
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 sides of pots or on the surface of the soil. The fronds are finely divided and lacy, giving the plant an airy appearance. It is primarily grown for its unique rhizomes and attractive foliage. While it can be grown indoors, it requires specific conditions to thrive and maintain its humidity needs. It is not naturally an indoor plant but can adapt with proper care.

❓ Frequently Asked Questions — Comparing These Plants
Cup Flower
What are the light requirements for Cup Flower?
Cup Flower requires bright, indirect light to thrive and produce abundant blooms. A location near an east- or west-facing window is ideal, providing several hours of gentle morning or afternoon sun. Avoid placing the plant in direct, intense sunlight, which can scorch the leaves. If growing indoors, supplement natural light with a grow light if necessary, especially during the winter months. Insufficient light can result in leggy growth, fewer blooms, and pale foliage. Rotate the plant regularly to ensure even light exposure on all sides. When growing outdoors, choose a spot that receives full sun for at least 6 hours a day, but with some protection from the harshest midday rays, especially in hotter climates.
How do I care for Cup Flower?
Cup Flower thrives with consistent care. Provide bright, indirect light, avoiding harsh direct sunlight. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Fertilize regularly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength, focusing on formulas higher in phosphorus to promote blooming. Maintain moderate humidity levels, especially indoors, by misting or using a humidifier. Prune spent flowers to encourage continuous blooming. Repot in spring every 1-2 years into a slightly larger pot with well-draining potting mix. Monitor for pests like aphids and spider mites, treating promptly with insecticidal soap or neem oil. Provide temperatures between 60-75°F (15-24°C) for optimal growth. Reduce watering and fertilization in the fall and winter as growth slows. Ensure good air circulation to prevent fungal diseases.
How do I propagate Cup Flower?
Cup Flower can be propagated through stem cuttings, division, and, less commonly, from keiki (small plantlets that grow on the parent plant). For stem cuttings, take 4-6 inch cuttings from healthy stems, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cuttings in moist potting mix and cover with a plastic bag to maintain humidity. Keep in a warm, bright location until roots develop (usually 4-6 weeks). For division, carefully separate the root ball of a mature plant into smaller sections, ensuring each section has healthy roots and stems. Replant the divisions in separate pots. Keiki propagation is rare, but if keiki develop, allow them to grow until they have roots, then carefully remove them and plant in their own pots.
Rabbit's Foot
What are the light requirements for Rabbit's Foot?
Rabbit’s Foot Ferns require bright, indirect light to thrive. Direct sunlight can scorch their delicate fronds, causing browning and damage. The ideal location is near an east- or north-facing window, where the light is filtered and gentle. If placing the plant near a south- or west-facing window, use sheer curtains to diffuse the sunlight.
How do I care for Rabbit's Foot?
Rabbit’s Foot Ferns thrive in bright, indirect light. Avoid direct sunlight, which can scorch the fronds. Water when the top inch of soil feels dry to the touch, typically once a week. Ensure good drainage to prevent root rot. Maintain high humidity by misting regularly, using a humidifier, or placing the plant on a pebble tray filled with water.
How do I propagate Rabbit's Foot?
Rabbit’s Foot Ferns can be propagated by division or spores. Division is the easier method. To divide, gently remove the plant from its pot and carefully separate the rhizomes into smaller sections, ensuring each section has healthy fronds and roots. Plant each section in its own pot with well-draining potting mix. Keep the soil consistently moist and provide high humidity until new growth appears.
