Use of the bearded iris

 

As 'flowers of the rainbow' irises cover the entire colour spectrum. Especially the single-coloured varieties of bearded iris are best shown to advantage when planted in smaller groups. Different coloured garden irises can also be combined to your heart's content. Their upright shape and narrow foliage create a beautiful structure in a perennial bed. A group of three is recommended, as too large a planted area quickly becomes unsightly after flowering. Irises can also be used as a border along a path.

A bearded iris plant can also be cultivated in a pot or tub, but it requires a lot of space. For a balcony, we recommend the dwarf bearded iris varieties, which have lower growing heights. When kept in a pot, an iris may need to be divided more often.

 

Which neighbours are suitable?

 

An iris is quite tolerant of drought, it can be combined well with other perennials and small shrubs that have similar site requirements. A good planting partner is for example lavender. Both have a beautiful Mediterranean appearance and complement each other with their different flowering times. Catnip, night violet or sage, oregano and thyme and euphorbia can also surround the bearded iris plant and take over the display when the iris has finished flowering.

 

Worth knowing

 

Botanically, the group of bearded iris plants belong to the genus Iris within the iris family (Iridaceae). It is the result of a cross between the dalmation iris (Iris pallida) and the variegated iris (Iris variegata). A conspicuous flower forms on high stems, which sometimes - depending on the variety - has a pleasant scent. Colourful hairs on the hanging leaves have given the bearded iris its name.

The varieties of the tall types reach growth heights between 50 and 120 centimetres. They all form a strong rhizome. Their little sisters (Iris Barbata-Nana, dwarf iris) remain considerably smaller at 20 to 40 centimetres. These beautiful perennials are hardy to about minus 28 degrees Celsius. Some varieties show a second flowering in midsummer.

 

Varieties in the Lubera®-Garden Shop

 

The colour spectrum of garden irises allows for all tones and shades. Even deep violet tones or flowers in black are available. Especially dark colours develop a very special kind of magic in the bed. Below are some recommendations from our assortment:

 

  • The variety 'Black Dragon' captivates with dark purple, almost black flowers and grows to about 80 cm high.
  • ‘Cherished' is a garden iris with delicate ruffled pale pink flowers.
  • Iris x barbata 'Natchez Trace' has chestnut-coloured, hanging leaves with an apricot thorn - a very special play of colours.

 

Location and soil

 

The optimal soil for this type of iris is loose, permeable, relatively rich in nutrients and rather dry. A sandy-loamy substrate is ideal. Too heavy garden soils should be mixed with a little sand before planting. Stagnant moisture and extreme dryness are not tolerated. The location should be full sun and warm.

The bigger the flowering, the more sheltered these irises should be - the lush splendour is a little susceptible to rain and weather.

 

Planting

 

The best time to plant the iris is after it has flowered in July, August or September because that is when it can establish itself.

If the soil is rather heavy, it is advisable to create a drainage layer of coarse sand at a depth of about 20 centimetres. The rhizomes are spread out horizontally in the soil and should protrude from the ground by about one third. Make sure that the roots point downwards. The distance between the individual plants can be quite generous: about 30 to 40 centimetres. Plants that are too densely planted must be divided again more quickly.

 

Care

 

Bearded iris plants are quite tolerant of heat and dryness. A freshly planted iris should, however, be watered regularly. Once it has grown in well, it only needs to be watered in the event of prolonged drought.

In the case of two time blooming varieties such as 'Cherished', wilted material should be removed to make room for the new flowering. Applying compost in the spring provides important nutrients, but excessive fertilisation should be avoided as rhizome rot can develop. A compound fertiliser low in nitrogen can also be used in the spring.

After flowering, the flower stalk can be cut off. However, the leaves should not be removed before the end of September. Stem or leaves should never be torn off, as there is a risk of wounds on the rhizome.

 

Rejuvenate and divide

 

To maintain the joy of flowering, dig the iris out every three to four years - preferably in August or six to eight weeks after withering. When the rhizomes are taken out of the soil, remove them and cut them into pieces about ten centimetres long with shoots and roots. The foliage is also shortened by ten centimetres (cut down in a wedge shape). The rhizomes are then replanted in another place. A bit of the top surface of the rhizome should be just visible at the soil surface. In this way, the plant is rejuvenated. The iris is also propagated by dividing the rhizomes.
