Buy Iris 'Mer du Sud' bearded iris: Stunning, violet flowers. Very free flowering

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

  • Position: full sun
  • Soil: well-drained, moderately fertile soil
  • Rate of growth: average
  • Flowering period: May and June
  • Hardiness: fully hardy

    A really arresting sight in May and June, when the violet flowers and cornflower-blue beards appear among sword-shaped, grey-green leaves. This may not be one of the fanciest irises around, but what it lacks in originality it makes up in quantity, flowering prolifically throughout early summer.

  • Garden Care: Plant shallowly with the upper part of the rhizome sitting on the surface of the soil, incorporating a low nitrogen fertiliser in the planting hole. After planting remove the upper-most third of the leaves to protect against wind-rock. In exposed areas stake with bamboo canes in early spring. Remove the stems after flowering from the base as this will concentrate the plant's energy into producing new rhizomes. Divide and replant about every three years.

Eventual height & spread

I purchased this iris mer de sud about 2 summers ago and it has yet to flower, should I give up or persevere??


Hello, It is quite common for bearded iris not to flower in their first year, but if they are getting plenty of sun and have not been planted too deeply, then I would expect to see some flowers in their second year. I would not give up just yet though, but feed it with Sulphate of Potash or Tomorite. Both of these are high in potash, which helps plants produce fruit and flowers, and this may give it a push in the right direction.


Iris Cliffs of Dover Hi Crocus Advice please. All the Iris 'Cliffs of Dover ' appear to have died back to ground level is this normal for Irises and will they reappear next season? Thanks Chris

Hello Chris These plants do die back at this time of the year so I would not be concerned and then put on lots of new growth in spring. Best regards, Helen Plant Doctor
