Cup Flower vs Matrimony Vine 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.
Matrimony Vine
Lycium barbarum
Lycium barbarum, commonly known as Goji Berry or Matrimony Vine, is a deciduous woody vine or shrub typically grown for its edible berries. It can reach heights of 1-3 meters. It features arching branches with lance-shaped, grayish-green leaves. While it can be grown in containers, it is primarily an outdoor plant that thrives in full sun and well-drained soil. People grow it for its nutritious berries, ornamental value, and traditional medicinal uses. Indoor cultivation is challenging due to its high light requirements and sprawling growth habit.

❓ 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.
Matrimony Vine
What are the light requirements for Matrimony Vine?
Matrimony Vine thrives in full sun, requiring at least 6 hours of direct sunlight each day to promote optimal growth and berry production. While it can tolerate partial shade, insufficient light can lead to leggy growth, reduced flowering, and fewer berries.
How do I care for Matrimony Vine?
Matrimony Vine requires full sun to partial shade, ideally at least 6 hours of direct sunlight daily. Water thoroughly when the top inch of soil feels dry, but avoid overwatering. Well-draining soil is crucial to prevent root rot. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer.
How do I propagate Matrimony Vine?
Matrimony Vine can be easily propagated through stem cuttings or layering. For stem cuttings, take 4-6 inch cuttings from healthy stems in spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist. Roots should develop in a few weeks.
