In the garden

Salvia x sylvestris 'Mainacht' belongs to the wide-ranging genus Salvia in the mint family Lamiaceae. The genus contains nearly a thousand species with a global distribution, so cultivar characteristics can vary; 'Mainacht' is offered as a garden cultivar intended to provide a defined period of summer flowers. Specific site, soil and hardiness requirements for named Salvias can differ between cultivars, so check the nursery label or supplier notes before planting. Many Salvia cultivars are positioned to make their summer flowering visible in the border or in containers; timing and pruning advice should follow the supplier’s instructions for that named clone. Plant spacing and seasonal care are best guided by the supplied cultural sheet where available. In UK planting schemes, a Salvia like 'Mainacht' is used to supply a concentrated run of flowers through the summer months and to bridge flowering gaps between other perennials.
