Iris Black Swan

Bearded Iris

Very vigorous and great fragrance

Bewitching inky black-purple flowers have a peppery scent and make this a beautiful cottage garden plant for the middle of a border where it will always be admired when in flower in early summer.


This plant loves to sunbathe in an open position in full sun.


Best in very well drained soil. Add coarse grit or sand to the base of the planting hole and plant so that the rhizomes - roots - are on top of the soil so that they are baked by the summer sun. Remove flower spikes once the blooms have faded and cut back the leaves by two thirds in summer to tidy them.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot. Dig compost into the base of the hole. Remove the pot and position the plant in the hole, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Water in well and keep well watered during the plant's first year.
