Cup Flower vs Jerusalem Cherry 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.
Jerusalem Cherry
Solanum pseudocapsicum
Solanum pseudocapsicum, commonly known as Jerusalem Cherry, is a small, shrubby perennial plant often grown as an annual. It features glossy, dark green leaves and produces small, white, star-shaped flowers followed by bright, round berries that ripen to orange or red. These berries are the plant's main ornamental feature. While visually appealing, all parts of the plant, especially the berries, are poisonous. It is primarily an outdoor plant, but is often sold as a temporary indoor decoration. It is grown for its colorful berries, which provide winter interest.

❓ 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.
Jerusalem Cherry
What are the light requirements for Jerusalem Cherry?
Jerusalem Cherry thrives in bright, indirect light. Avoid direct sunlight, which can scorch the leaves and damage the plant. An east-facing window is ideal, providing gentle morning sun. A west-facing window can work, but monitor for leaf scorch during the hottest part of the afternoon. If you don’t have access to adequate natural light, consider using a grow light to supplement.
How do I care for Jerusalem Cherry?
Jerusalem Cherry requires bright, indirect light; direct sunlight can scorch the leaves. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain a moderate humidity level, especially during the winter months when indoor air tends to be drier. Fertilize every 2-3 weeks during the growing season (spring and summer) with a balanced liquid fertilizer, diluted to half strength.
How do I propagate Jerusalem Cherry?
Jerusalem Cherry can be propagated by stem cuttings. Take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and dip the cut end in rooting hormone.
