Heliotropium europaeum, commonly known as European Heliotrope or Common Heliotrope, is an annual plant in the Boraginaceae family. It is native to Europe and Asia but has spread to other subtropical regions. The plant is known for its small, white, fragrant flowers that bloom in clusters. It thrives in subtropical climates and is often found in disturbed soils, such as roadsides and fields.
European Heliotrope prefers bright, direct sunlight and should be placed in a location where it can receive at least six hours of sunlight daily. It thrives in moderate temperatures and does well in average humidity levels. Water the plant when the soil is almost completely dry, but avoid overwatering as it can lead to root rot.
土壤
This plant prefers well-draining loamy soil with a slightly acidic to neutral pH. Ensure the soil dries out almost completely between waterings to prevent root rot. Good drainage is essential for the health of the plant.
肥料
Use a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant once a month during the growing season to promote healthy growth and flowering.

Repotting is generally not necessary for this annual plant. However, if you are growing it in a container, ensure the pot has good drainage and consider refreshing the soil at the beginning of the growing season.
传播
European Heliotrope can be propagated by seeds. Sow the seeds in well-draining soil in a sunny location. The best time to propagate is in the spring when temperatures are moderate.
修剪
Pruning is not typically required for this plant. However, you can remove any dead or damaged leaves to maintain its appearance and health.
