Its seasonal display aligns with the genus's summer performance, offering a sustained period of bloom through the warmer months. Give 'Grappenhall' a sunny position and soil that sheds water quickly: suitable substrates include chalk, loam or sand. The plant tolerates a broad soil pH range (acid to alkaline) but will not thrive in poorly drained ground. It suits south-, west- or east-facing aspects and can be grown in both sheltered courtyards and more exposed sites. The hardiness rating H5 classifies it as hardy in UK terms. Use 'Grappenhall' where a summer-flowering, evergreen shrub is helpful: flower borders and beds, gravel gardens, banks and slopes, city courtyards, patios and containers, and cottage or informal plantings. It is also appropriate for wildlife-friendly schemes and Mediterranean-style plantings. Its long flowering season from June to September provides a reliable summer presence in the situations above.
