Buy Salvia × sylvestris 'Mainacht' salvia May Night: Large indigo-blue flowers

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

  • Position: full sun or partial shade
  • Soil: light, moderately fertile, humus-rich, moist but well-drained soil
  • Rate of growth: average
  • Flowering period: June to July
  • Hardiness: fully hardy

    A delightful, colourful plant with spikes of indigo-blue flowers in early to midsummer. This reliable perennial is ideal for the middle of a moist, well-drained herbaceous border. It flourishes in sun or dappled shade where the bright flowers help to liven up any plant scheme.

  • Garden care: To prolong flowering remove the flower spikes as soon as they start to fade. Apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant in spring.

Wouldn't buy again because snails and slugs like this plant


Unfornately I bought 3 plants snails and slugs love this plant in my garden and just kept devastating them. I protected them with wire mesh and they still got at this plant. Unfortunately, no good for my garden.




Just lovely!


In my opinion, the best of salvias! I can't grow lavender on London clay so this is my substitute plant. The most beautiful purple that goes well with every colour but looks particularly well with white or deep reds. If cut after the first flush it will flower again by September, not as abundantly but enough to provide seconds for bees and bumblebees. Highly recommend.




Lovely colour goes with everything


Nice healthy plant. Lovely purple colour. No pest issue. Appears to be coming back ok after winter.




Fantastic flowers


Lovely scent, great colour and loved by the bees. Keeping pruning the dead flowers and they just go on and on.....




Long flowering and the bees love it


provides colour for June and July and the bees love this one. Really like its verticle interest and it looks great with grasses such as Stipa tenuissima

First class


Good size plants that established well






Looks fine while in flower, but quite soon goes off. Cut back and it will flower again, but looks untidy and not very attractive. Also spreads itself in an unattractive manner. Pros, the bees love it, and that is why it still has a space in my garden

Vigorous and healthy, prolific dark blue flower spikes which last well and repeat flower if deadheaded. A really good buy.
