If you live in a coastal area or have a garden with poor soil, Centranthus ruber ' Albus' is a great choice of plant. The hardy perennial isn't fussy: if planted in a sunny border, it will flourish regardless of soil type. This Valerian can also withstand drought, wind & exposure, producing pure white blooms in dainty clusters throughout the summer, whatever the weather.
