About May Night Sage

Botanically, Salvia x sylvestris 'Mainacht' is a moderate-growing perennial in the Lamiaceae family. It reaches around 50 cm tall and 45 cm wide at maturity, with aromatic and deciduous foliage. Purple and blue flowers appear for much of the year.

Where to grow May Night Sage

May Night Sage suits cool-temperate, warm-temperate and Mediterranean climates and grows best in full sun. It is frost hardy and shrugs off cold winters. It also is a genuinely water-wise choice and is an award-winning selection.

Soil & planting

May Night Sage does best in free-draining soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.

Watering & feeding

May Night Sage performs well with relatively little water once established. A light spring feed is usually enough to maintain steady growth. For the first year, favour occasional deep watering over frequent shallow drinks so roots move into the surrounding soil.

Pruning & care

Prune May Night Sage after flowering to keep it compact and encourage the next flush of blooms. Expect a low maintenance care workload once it is established.

Using May Night Sage in the garden

May Night Sage earns its place for feeding bees and pollinators, attracting butterflies, cut flowers for the vase and a feature or specimen planting.

Companion planting & design

For easier irrigation and care, group May Night Sage with species that also favour happy on low water and cool-temperate climate. Leave enough room for the mature spread so neighbouring plants are not crowded out.

Good to know

It is regarded as non-toxic and pet-safe.
