How to care for Festuca glauca Intense Blue ('Casblue') (PBR):

Festuca thrives in well-drained soil and a sunny position, where its striking blue foliage remains vibrant year-round. When planting, improve drainage by incorporating grit or sand if the soil is heavy.

Water well after planting, but once established, it becomes more drought-tolerant though will benefit from additional irrigation during dry periods to maintain colour. Container-grown specimens should be watered regularly while they establish but avoid waterlogging.

In winter, comb through the plant with your fingers to remove dead foliage and maintain its neat appearance.
