Stand:

Bright, half shade, in summer gladly outside the house, no full sun.
The N. northiana endures too a place in the shade behind a net curtain or at a distance of 50 cm (app. 20 inch ) from the window.
The temperature should always be over 15° C  (59° F), because else there's the real danger of pests.

Bloom:

Obviously the plants undertake at germination the local seasons. 

The flower stem looks first like a somewhat thicker leaf. Each stem can make it up till 10 blooms, after each other, but also simultaneously. The bloom opens itself in the morning, in the afternoon it is fully blooming and in the evening already faded.

My flowering periods:

N. candida

N. northiana

N. Guaratuba

Trimezia fosteriana

Dietes iridioides

december-january

february-may

Propagation:

The flowering stem grows on in the length during the blooming. 2 meters (app. 6,5 ft.) are no exception here. Therefore it has to be sustained well. At it's end a layer is developed, which would in free nature directly sinks to the ground, roots and forms a new plant. (That explains the name "Walking iris"). When the layer is standing upright at the flowering stem it can cut off together with a little part of the stem. Then the husk has to be removed very carefully. The layer can pottet directly in soil or put fist in water until the first roots appear.

When it is time to repot, the rhizomes can be parted and each one separated pottet.

Other caring information:

The Walking iris always need to have enough water, temporary wet 'feet' doesn't bother her really. That is why she can kept fine in hydroculture. It should be rotatory toweled down. At lower temperatures she needs less water, but humidity for a longer time causes root rotting.

App. 2 months before the blooming season she should be fertilized weekly with a dung for flowering plants, which contains more phosphate than nitrogen. The species which bloom just once, should get after the flowering period weekly normal plant fertilizer.

Now and then the leaves should be cleaned with a moisted towel. Brown tips, which are mostly caused by too much sun, can simply cut off.

Repotting should be done, when it is obvious, that the pot becomes too tight. Use then soil of really high quality. (Gardening soil).

Pesticide:

Dry room air or through contagion spider mites, scale insects and even plant lice (Aphids) can easily discover the 'delicious' iris leafs. An appropriate spray for house plants can be endured by these plants.

Don't use the so called "combination granules", the high content of nitrogen seems to be poison for Neomaricas.

Attention:

Cats love chewing the leafs, it is not good for the plant, but it isn't dangerous for the cats, the plant isn't poisonous. My two cats 'survived' it fine. For my canary bird the leafs are too hard, but tasting didn't harm him either.
