Chicory vs Old Man Cactus Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Chicory
Cichorium intybus
Chicory is a herbaceous perennial plant typically grown outdoors. It features a rosette of basal leaves and a tall, branching flower stalk that can reach up to 1.5 meters in height. The plant is known for its bright blue, daisy-like flowers that open in the morning and close in the afternoon. Chicory is cultivated for its leaves, which are used in salads, and its roots, which are roasted and used as a coffee substitute. It's also grown as a forage crop for livestock. While technically possible to grow indoors, it's challenging to provide the necessary sunlight and space.
Old Man Cactus
Cephalocereus senilis
Cephalocereus senilis, the Old Man Cactus, is a columnar cactus characterized by its dense covering of long, white hairs that resemble an old man's beard. This slow-growing cactus can reach heights of up to 15 feet in its native habitat, but typically remains smaller in cultivation. The white hairs serve to protect the plant from intense sunlight and frost. It is primarily an outdoor plant, thriving in arid environments with full sun. People grow it for its unique appearance and novelty.

❓ Frequently Asked Questions — Comparing These Plants
Chicory
What are the light requirements for Chicory?
Chicory requires at least six hours of direct sunlight per day to produce abundant blooms. Place Chicory in a location that receives full sun, such as a south-facing garden or a sunny windowsill if grown indoors. Insufficient light can result in leggy growth, reduced flowering, and pale foliage. If growing indoors, supplement natural light with grow lights during the winter months to ensure adequate light exposure. Rotate the plant regularly to ensure even light distribution on all sides. Monitor the plant for signs of light stress, such as scorched leaves, which may indicate excessive light exposure.
How do I care for Chicory?
Chicory thrives in well-drained soil and prefers full sun exposure for optimal blooming. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Fertilize sparingly, using a balanced fertilizer diluted to half strength, only during the growing season (spring and summer). Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers. Prune spent flowers to encourage further blooming. Chicory is relatively drought-tolerant once established. Protect young plants from slugs and snails. Monitor for common pests like aphids and treat as needed with insecticidal soap. Provide support for taller varieties to prevent them from flopping over. In colder climates, Chicory can be grown as an annual.
How do I propagate Chicory?
Chicory can be propagated by seed, root division, or root cuttings. For root division, carefully dig up the plant in early spring or fall and divide the root ball into sections, ensuring each section has healthy roots and shoots. Replant the divisions in well-draining soil. For root cuttings, take 4-6 inch sections of root in late fall or early spring. Lay them horizontally in a tray of moist sand or potting mix, covering lightly. Keep moist until new shoots appear, then transplant. Seed propagation involves sowing seeds directly into the garden in spring or fall, or starting them indoors 6-8 weeks before the last frost. Keep the soil consistently moist until germination.
Old Man Cactus
What are the light requirements for Old Man Cactus?
Old Man Cactus thrives in bright, direct sunlight. Ideally, place it near a south-facing window where it can receive at least six hours of sunlight each day. Insufficient light can cause etiolation, where the cactus becomes elongated and pale.
How do I care for Old Man Cactus?
The Old Man Cactus requires a bright, sunny location with at least six hours of direct sunlight per day. Use a well-draining cactus mix and water sparingly, only when the soil is completely dry. Overwatering is a common cause of root rot, so be cautious. Fertilize sparingly during the growing season (spring and summer) with a diluted cactus fertilizer. During the winter dormancy, withhold watering and fertilization altogether.
How do I propagate Old Man Cactus?
Old Man Cactus can be propagated by offsets, seeds, or grafting. Offsets that grow at the base of the plant can be carefully removed and planted in well-draining cactus mix. Allow the offset to callous over for a few days before planting.
