A strange iris seedling

Ivan21(7b)April 29, 2013

Here is a picture of some iris seedlings I crossed last year, stratified in the fridge for a month and later planted in some soil mix. I have been spray watering them every 3 to 4 days.

As you can see one of them is completly white (lack of chlorophyl?). Currently the white one is beginning to sag a bit and I think it might not make it. Has anyone ever seen a simillar seedling?

The little plants are about 3 inches high at the moment, are they ready to transplant outside? Should I cut the longer leaves down a bit because they are very unstable due to fast growth indoors?

Thank you for any helpful answers.

yes I have had a few of those also. They don't live too long.

The earlier you can plant out your seedlings the better chance you have of getting them to bloom next Spring. 3 inches tall is plenty big enough, just be sure to protect from snails etc.

Don't cut the leaves. They're manufacturing food for the rhizome.

Chad, can the floppy leaves be due to frequent watering?

Looks like the seedlings are inside, so I'd go with not enough light - coming from the side - and making them lean.
I guess your comment on cutting the leaves refers to the usual practice of trimming fans before transplanting, yes this only needs to be done if the rhizomes have been removed from the soil and have lost roots in the process.

When I separate seedlings which have grown together ( I use 1 gallon pots or 4" pots) I put the whole mass into a water bath to make it easier to separate the roots. Then the seedlings are planted out immediately and shaded if the weather is really hot... That's another reason to move them out in the Spring.
