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.
Space plants around 30cm (12in) apart to allow for good air circulation. 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.
To keep plants looking fresh, divide clumps every few years or replace them if they become too woody or untidy.
