Maidenhair Tree 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.
Maidenhair Tree
Ginkgo biloba
Ginkgo biloba, the Maidenhair Tree, is a unique species of tree with no close living relatives. It's characterized by its fan-shaped leaves that turn a vibrant golden yellow in the fall. Ginkgos are dioecious, meaning there are separate male and female trees. Female trees produce seeds with a fleshy outer layer that has a strong, unpleasant odor when ripe. Ginkgos are incredibly resilient and long-lived, often planted as ornamental trees in parks and gardens. They are deciduous and known for their resistance to pests and pollution. While young trees can be grown in containers, they are primarily outdoor trees.
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
Maidenhair Tree Care Tips
Ginkgo biloba is primarily an outdoor tree and is extremely challenging to grow indoors due to its need for full sun, large size, and dormancy requirements. While young trees can be kept in containers for a short time, they will eventually need to be planted outdoors. Indoor cultivation is not recommended.
- Plant in well-draining soil to prevent root rot.
- Water deeply but infrequently, allowing the soil to dry out slightly between waterings.
- Fertilize in spring with a balanced fertilizer.
- Prune young trees to establish a strong central leader.
- Protect young trees from extreme cold and wind.
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.
