Blanket Flower vs Cup Flower Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Blanket Flower
Gaillardia spp.
Blanket flowers are vibrant perennials known for their daisy-like flowers in warm shades of red, orange, and yellow, often with contrasting bands of color. They typically grow 1-3 feet tall and wide, forming a bushy clump. Gaillardia are primarily outdoor plants, prized for their long bloom period from summer to fall. They are drought-tolerant and attract pollinators, making them popular in gardens and meadows. While they can be grown in containers, they are not naturally indoor plants and require very specific conditions to thrive indoors.
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.

💡 Pro Tips For Comparing These Plants
Blanket Flower Care Tips
Blanket flowers are easy to care for outdoors, but challenging indoors due to their high light requirements. They need full sun and well-draining soil. Overwatering is a common problem. Indoor growth is often stunted and flowering is significantly reduced.
- Deadhead spent flowers regularly to encourage more blooms.
- Provide well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
- Fertilize lightly in spring with a balanced fertilizer.
- Divide clumps every few years to maintain vigor.
Cup Flower Care Tips
Cobaea scandens is primarily an outdoor plant. Growing it indoors is challenging due to its high light requirements and vigorous growth. It needs ample space, strong support, and regular pruning to manage its size. Providing adequate light is crucial for flowering indoors.
- Provide a strong support structure for the vine to climb.
- Water deeply but infrequently, allowing the soil to dry slightly between waterings.
- Fertilize regularly during the growing season to promote vigorous growth and flowering.
- Prune regularly to control size and shape, especially indoors.
- Monitor for pests and diseases and treat promptly.

❓ Frequently Asked Questions — Comparing These Plants
Blanket Flower
What are the light requirements for Blanket Flower?
Blanket Flowers require at least six hours of direct sunlight per day to thrive and produce abundant blooms. Inadequate sunlight can result in leggy growth, fewer flowers, and duller colors. When planting Blanket Flowers, choose a location that receives full sun exposure throughout the day. If growing in containers, place them on a sunny patio or balcony. If you live in a very hot climate, some afternoon shade may be beneficial to prevent scorching. Consider the sun’s angle throughout the day and ensure that taller plants do not cast shadows on your Blanket Flowers. Rotate container plants regularly to ensure even light exposure on all sides.
How do I care for Blanket Flower?
Blanket Flowers thrive in full sun and well-drained soil. Water thoroughly when the top inch of soil feels dry, but avoid overwatering, as they are drought-tolerant. Fertilize lightly in spring with a balanced fertilizer to encourage blooming. Deadhead spent flowers regularly to promote continuous blooming throughout the summer and fall. Prune back foliage in late fall or early spring to encourage new growth. Blanket Flowers are generally hardy and pest-resistant. Ensure good air circulation to prevent fungal diseases. They are typically grown outdoors. If growing in containers, choose a well-draining potting mix and ensure the container has drainage holes. Divide clumps every few years to prevent overcrowding and maintain vigor.
How do I propagate Blanket Flower?
Blanket Flowers can be propagated by division, seed, or root cuttings. Division is best done in spring or fall. Dig up the clump and divide it into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-drained soil. To propagate from seed, sow seeds indoors 6-8 weeks before the last expected frost or directly outdoors in spring. Root cuttings can be taken in late spring or early summer. Take a 4-6 inch cutting from a healthy root and plant it in a pot with well-draining soil. Keep the soil moist until new growth appears. Keiki propagation is not applicable to Blanket Flowers.
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.
