Once established, this species exhibits good drought tolerance, making it suitable for low-maintenance landscapes.

  • Watering Guide: Provide the plant with regular watering, particularly during periods of extended dryness. Allow the soil to dry slightly between watering sessions to prevent waterlogged conditions, which can be detrimental to the plant’s health.


Tickseed thrives in full sun to partial shade. Adequate sunlight is crucial for promoting robust growth and abundant flowering.

  • Sunlight Requirements: When selecting a planting site, ensure that it receives at least 6 hours of direct sunlight daily. In regions with intense summer heat, some afternoon shade may be beneficial to prevent stress on the plant.


Moderate fertilization can enhance the growth and flowering of Coreopsis ‘Limerock Passion’. However, it is important to exercise caution to avoid excessive fertilization, which may result in leggy growth and reduced flowering.

  • Fertilization: Apply a balanced granular fertilizer in early spring or late winter, following the manufacturer’s recommendations for application rates. Refrain from overfeeding, and aim to support healthy, vigorous growth without stimulating excessive foliage at the expense of flowers.


The choice of soil is a critical factor in ensuring the optimal growth and performance of Coreopsis ‘Limerock Passion’.
