Tripleurospermum inodorum, commonly known as scentless mayweed, is a member of the Asteraceae family. It is native to Europe and Asia but has spread to other temperate regions. This plant is an annual or biennial herb that thrives in disturbed soils and is often found in fields, roadsides, and waste areas.
Tripleurospermum inodorum prefers full sun and moderate temperatures. It is relatively easy to care for, requiring minimal watering once established. The plant can tolerate a range of humidity levels but prefers moderate conditions.
Soil
This plant prefers well-draining loamy soil. It can tolerate a range of soil types but thrives best in nutrient-rich, slightly acidic to neutral soils. Ensure the soil dries out almost completely between waterings to prevent root rot.
Fertilizer
Tripleurospermum inodorum does not typically require fertilization. If the soil is particularly poor, a balanced, all-purpose fertilizer can be applied sparingly.
Repotting
As an annual or biennial, Tripleurospermum inodorum does not require repotting. However, if grown in containers, ensure the pot has good drainage and consider refreshing the soil annually.
Propagation
Propagation is typically done by seed. Sow seeds directly in the ground in early spring or late fall. The seeds require light to germinate, so do not cover them with soil.
Pruning
Pruning is not necessary for this plant. However, deadheading spent flowers can encourage more blooms and prevent self-seeding if desired.
Toxicity
Tripleurospermum inodorum is not known to be toxic to pets or humans. However, as with all plants, it is best to prevent ingestion by pets and children.
