Chives vs Cup Flower Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Chives
Allium schoenoprasum
Chives are a perennial herbaceous plant characterized by their hollow, cylindrical, grass-like leaves that grow in clumps. They typically reach a height of 10-30 cm. Chives are primarily grown for their culinary uses, adding a mild onion-like flavor to dishes. They produce attractive, globe-shaped clusters of lavender-pink flowers in the late spring or early summer. While chives can be grown indoors, they thrive outdoors in gardens or containers where they receive ample sunlight. People grow them for their edible leaves and attractive flowers.
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.

❓ Frequently Asked Questions — Comparing These Plants
Chives
What are the light requirements for Chives?
Chives thrive in bright light, needing at least 6 hours of direct sunlight per day. An east- or south-facing window is ideal for indoor chives. Insufficient light can lead to leggy growth and reduced flowering. If your chives aren’t getting enough natural light, consider supplementing with a grow light. Place the light 6-12 inches above the plant for 14-16 hours a day. Rotate the plant regularly to ensure even light exposure on all sides. During the summer months, be mindful of intense afternoon sun, which can scorch the leaves. A sheer curtain can help diffuse the light. Outdoor chives also benefit from full sun, but can tolerate partial shade, especially in hotter climates.
How do I care for Chives?
Chives are remarkably easy to care for, making them ideal for beginners. Plant in well-draining soil with a slightly acidic pH (6.0-7.0). Provide at least 6 hours of direct sunlight daily; indoor chives benefit from a sunny windowsill. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize every 2-3 weeks during the growing season (spring-summer) with a balanced liquid fertilizer diluted to half strength to encourage blooming. Cut back the foliage regularly to promote new growth and prevent the plant from becoming leggy. Deadhead spent flowers to encourage more blooms. In colder climates, provide winter protection by mulching or bringing potted chives indoors. Repot every 2-3 years to refresh the soil and provide more space for the roots. Monitor for pests like aphids and spider mites, and treat as needed with insecticidal soap.
How do I propagate Chives?
Chives are easily propagated by division. In spring or fall, carefully dig up the plant and separate the clumps of bulbs. Replant the divisions in well-draining soil, spacing them a few inches apart. Water thoroughly. Alternatively, you can propagate chives from seed. Sow seeds indoors 6-8 weeks before the last frost. Keep the soil moist and warm. Transplant seedlings outdoors after the danger of frost has passed. Chives do not typically produce stem cuttings or keikis, so division is the most reliable propagation method. Ensure each division has healthy roots for successful establishment. Propagating chives allows you to expand your garden and share these versatile herbs with friends and family.
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.
