Iris barbata, cultivation: how to grow irises. Details on flowering, planting and plant care.
Theiris barbatethey are very easy tocultivate, these are spontaneous plants that in country gardens are known aswild irises. They present an interestingfloweringwhich varies in color according to the variety (pink, dark blue, purple, orange, purple…). They bloom together with roses, peonies and columbines.
Iris barbata, cultivation: flowering and planting
L'iris barbatabelongs to the genusIris, this rhizomatous perennial herbaceous plant shows off showy flowers and there are about 250 known species native to Europe, Asia and North America.
Depending on the height of development they are divided intotall beards, intermediate barbate anddwarf beards.
The tall beardsthey develop in height up to 90 - 120 cm. They bloom by May.
The intermediate barbatethey develop in height between 30 and 70 cm and flowering occurs around April.
Thedwarf beards they have a very limited development, between 35 and 70 cm in height. The flowering ofdwarf beardsdevelops by March.
Thedwarf beards, as well as the other bearded irises, must be planted from June until the end of summer. In the same period it is possible to proceed with the multiplication with division of the rhizome.
For thecultivation ofiris barbata, choose a possibly sunny position (the plant must have at least half a day of sunshine). THEirisesthey develop well in calcareous-clayey soil, well drained and with a good quantity of organic substance.
Before thecultivation, prepare the soil with a shallow digging (25 - 30 cm) by burying organic fertilizer (well-mature manure is recommended). This preparation must be done before the planting of therhizomes which must be buried superficially with the upper part of the rhizome emerging from the ground.
As soon as the rhizomes are planted, irrigate in moderation.Warning!You don't have to wet the soil heavily but just make sure the soil sticks to the roots.
The planting and cultivation needs are similar for all the irises mentioned. The only difference is the distance of the plant:
- L'tall bearded iristhey must be planted at a distance of 30 - 40 cm from each other.
- for theiris barbata nanathe installation distance to be respected is 5 - 10 cm.
- the intermediate-growing bearded iris should be planted at a distance of about 20 cm from each other.
Iris barbata or irises, multiplication
Propagation can be done easily to get new seedlings. The multiplication ofirisestakes place after theflowering, from June to September. Wait for the temperatures to increase also foriris barbata nanawhich blooms around March. The ideal period for the multiplication of irises falls between June and early September, we advise you not to go beyond the second half of September because the rhizomes will be completely mature and more difficult to manage by the arrival of the first autumn colds.
Propagation by division of rhizomes is simple. Here's how to proceed:
1) With a small spade, uproot the plant from the ground and place it on a work surface.
2) With your hands, separate the rhizomes and remove the excess soil that you have pulled up with the plant.
3) With a shears, separate the individual rhizomes, making sure that each one has at least one tuft of leaves.
Each piece of rhizome that has a tuft of leaves will give rise to a new plant ofiris barbatato grow in pots or in the garden. Bury the rhizomes obtained superficially, also in this case, the upper part of the rhizome must emerge from the ground just as explained in the paragraph dedicated tocultivation and planting of bearded iris.
Potted bearded iris
THEirisesthey can also be grown in pots. The cultivation of irises in pots is carried out with the same instructions seen for cultivation in the garden.
To start, grow bearded iris in pots with a diameter of 30 - 40 cm. The substrate to be used is made up of sack peat, field earth and pumice (or lapilli) in equal parts. Also in this case the rhizome must be buried very superficially, leaving almost half of its thickness visible.
