Bulbing iris are beardless - and bloom from February through July.
There are 3 groups :
'junos’ - Bulbing Juno Iris, subgenus Scorpiris - one of the more popular bulb irises in cultivation, generally earliest to bloom.
Bulbing European Iris, subgenus Xiphium which are generally of European descent, with Iris reticulata and Iris persica, fragrant and popular with florists, or Iris xiphium and Iris latifolia, with very showy flowers. They are among the hardier bulbous irises, and easy to grow in colder climates.
Bulbing Reticulate Iris, subgenus Hermodactyloides, with their characteristic bulbs, popular spring bulbs and among the first to bloom in the garden.
Sometimes called Irish Iris or Dutch Iris, bulbous irises have a buried storage organ.
They carry beardless flowers from February to July.
Reticulata irises bear two long leaves with a square or cylindrical section. Leaves increase by 30 cm after flowering. Blue, white or purple-red flowers.
Juno irises have flattened or fluted leaves. The flowers have large, colorful sepals and small petals.
Xiphium irirs have linear, fluted leaves with blue, yellow or white flowers.
Plant my bulbing iris
Plant in October in the sun or in semi-shade, in well-drained soil, quite rich. Iris Xiphium and Juno plant every 10-15 cm depending on their vigor. Reticulata are planted every 5-10 cm. Bury all bulbous irises by twice the height of the bulb, bulging part at the bottom.
Water my bulbing iris
It may be necessary, at the resumption of vegetation and during flowering, to sprinkle copiously the spring bulbs-in a well-drained soil. For potted bulbs and indoors, water weekly during the growing season. Do not water in the summer during the dormancy period.
Fertilize my bulbing iris
Fertilize the base of the bulbs in November with a layer of compost or decomposed manure.
Propagate my bulbing iris
Tear off and divide the bulbs in September if you wish to multiply them.
Mulch my bulbing iris
Mulch your bulbs in the fall to limit the next weeding. A layer of leaves and shredded wood should suit well.
