Bush Clover vs Old Man's Beard Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Bush Clover
Lespedeza spp.
Bush clovers are a diverse group of herbaceous perennials or subshrubs, typically characterized by their trifoliate leaves and pea-like flowers. They range in height from a few inches to several feet, depending on the species. Many species are valued for their drought tolerance and ability to thrive in poor soils, making them useful for erosion control and wildlife habitat. While some species are considered invasive in certain regions, others are cultivated for ornamental purposes or forage. They are primarily outdoor plants and do not thrive indoors.
Old Man's Beard
Usnea spp.
Old Man's Beard is a lichen, not a plant. It's a symbiotic relationship between a fungus and an alga or cyanobacterium. It appears as stringy, hair-like strands hanging from trees and shrubs. Its color ranges from pale green to grayish-green. It thrives in humid environments with clean air. People collect it for its purported medicinal properties and decorative uses. It is primarily an outdoor organism and cannot be successfully grown indoors.

💡 Pro Tips For Comparing These Plants
Bush Clover Care Tips
Bush clover is primarily an outdoor plant and is very challenging to grow indoors due to its high light requirements and need for seasonal dormancy. It requires full sun, well-draining soil, and moderate watering. Indoor cultivation is not recommended.
- Plant in well-draining soil to prevent root rot.
- Provide full sun for optimal growth and flowering.
- Water deeply but infrequently, allowing the soil to dry out between waterings.
- Prune in early spring to remove dead or damaged growth and shape the plant.
- Monitor for pests and diseases and treat promptly.
Old Man's Beard Care Tips
Old Man's Beard is an outdoor lichen that is extremely difficult to cultivate indoors. It requires very high humidity, clean air, and specific lighting conditions. It is not a suitable houseplant and will likely die indoors.
- Provide high humidity through regular misting or a humidifier.
- Ensure good air circulation to prevent fungal growth.
- Protect from direct sunlight, especially during the hottest part of the day.
- Monitor for signs of drying out and adjust humidity accordingly.
- Avoid using tap water for misting, as it can contain minerals that harm the lichen.

❓ Frequently Asked Questions — Comparing These Plants
Bush Clover
What are the light requirements for Bush Clover?
Bush Clover requires at least six hours of direct sunlight per day for optimal growth and abundant flowering. While it can tolerate partial shade, insufficient sunlight can lead to leggy growth and reduced bloom production. In hotter climates, some afternoon shade can be beneficial to prevent scorching of the foliage. When planting Bush Clover, choose a location that receives ample sunlight throughout the day. If growing in containers, rotate the plant regularly to ensure even light exposure on all sides. Monitor the plant’s growth and adjust its location as needed to provide the appropriate amount of light. South-facing locations are generally ideal.
How do I care for Bush Clover?
Bush Clover thrives in well-draining soil and requires full sun to partial shade for optimal growth and flowering. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Prune annually in late winter or early spring to remove dead or damaged branches and to maintain the desired shape. Bush Clover is relatively drought-tolerant once established. Protect from extreme cold in colder climates with a layer of mulch around the base of the plant. Monitor for pests and diseases, and treat promptly if necessary. Provide support for taller varieties to prevent them from sprawling. Ensure good air circulation to prevent fungal diseases. Regularly check the soil moisture to ensure proper watering.
How do I propagate Bush Clover?
Bush Clover can be propagated through several methods, including division, stem cuttings, and seed. Division is best done in early spring or fall. Carefully dig up the plant and divide the root ball into smaller sections, ensuring each section has healthy roots and shoots. Replant the divisions in well-draining soil. For stem cuttings, take 4-6 inch cuttings from new growth in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a moist, well-draining potting mix and keep them in a humid environment until they root. Seeds can be sown in early spring after stratification (cold treatment). Keep the soil moist and warm until germination occurs.
Old Man's Beard
What are the light requirements for Old Man's Beard?
Old Man’s Beard thrives in bright, indirect light. Direct sunlight can scorch its delicate foliage, causing it to dry out and turn brown. The ideal location is near an east- or west-facing window where it receives filtered sunlight. If you’re using artificial light, provide it with several hours of fluorescent or LED grow lights daily.
How do I care for Old Man's Beard?
Caring for Old Man’s Beard is relatively simple, but understanding its needs is crucial for its health and longevity. Place it in a location with bright, indirect light. Avoid direct sunlight, which can scorch the delicate foliage. Water by misting the plant thoroughly 2-3 times a week, or soaking it in water for 15-30 minutes every 1-2 weeks. After soaking, gently shake off excess water to prevent rot.
How do I propagate Old Man's Beard?
Old Man’s Beard is primarily propagated through pups, or offsets, that grow from the main plant. Once a pup reaches about one-third the size of the mother plant, it can be carefully separated. Gently pull or cut the pup from the main strand, ensuring you don’t damage either plant.
