how to tell types of iris

Posted by ginnypenny Tyler TX area (My Page) on

Past history: got a bunch of iris from the daughter ofaa guy in Bonham, TX. He raised and sold them, when he went into a nursing home, she didn't want them. They ignored for several years. Some were in bloom some weren't when I got them. I brought them to Jacksonville, TX and planted them a 1 acre small garden. They are in full sun at least 5 to 6 hours a day. The soil is sand, but we put lots of mulch, etc. in when we planted them. And have mulched them each winter...now I know I shouldn't have done that! Put them in checkerboard fashion. This was four or five years ago.

Since then, I was on the road and was not here to take care of them. Now I'm back and have finally pulled all the weeds out. PROBLEM 1, I have no idea what is what.
I know some were bearded, some not, some are the old fashion 'flags, etc. I'm guessing I'll have to wait until they bloom to be able to tell what is what?

PPROBLEM 2. Most of them have sunk way below the surface.
Everything sinks here I have to reset my paving stones, etc every year. Many of them ..the irises not the paving stones... are very small with no or practcally no rizome. Since I weeded, lots are showing up.

Should I wait until spring to do anything? Or pull them up where they are so they are not so deep? Should I feed them now or wait to see what survives the winter? We usually have mild winters here in East Texas.

Any help will be much appreciated

RE: how to tell types of iris

It's really tough to tell which Iris is what kind by the foliage alone, with a few exceptions, such as Dutch Iris, and some of the odd tuberous-rooted species from central Asia. If you have any idea what you had to begin with, even if not where it is now, you could make some educated guesses from what is coming up.

For instance, "Leaves 1/2"-3/4" wide and growing straight up: that must be one of the spurias I planted!" Or, "Leaves blue-gray and curved strongly to the outside: did I have any Arilbreds?"

As for them sinking, I've never heard of such a thing, before! Usually, Iris tend to rise to their preferred depth as they grow. They should do that in this case, too, but you may not get much bloom this spring. Have you been getting a lot of flooding, with silt washing in? Someone more familiar with the area may have to help with the sinking problem. You should still be able to replant the bulbs, especially if you can keep root disturbance to a minimum, though that will also tend to reduce bloom.

It sounds like a project. Good luck! : )

Thanks for the quick reply. I had forgotten that I made pictures of the bed the first year. Will look on the old computer to see if they are still there.

I also thought iris tended to rise, but mine definitely have not. None of them had the rizomes showing. And I know we did not plant ALL of them, around 150, that deep. The garden does slant down towards a swampy area, but DH's Grandfather used it for the 'house' garden and I don't remember problems with those plants. This fall we have had lots and lots of rain, and so could have had some silting. But they really look as if they have been down deep for some time.

I don't mind losing some blooms this spring, if I can save the plants....hopefully I have lots of years to enjoy them!
I thought about just lifting them where they are and packing dirt under them. The roots are quite long and look healthy...but many show no or little actual rizsome.

What are you thoughts about feeding or adding bone meal at this time? I have so many projects to keep me busy that I meet myself coming and going...That's what being on the road for 3 years will do for you. Oh well, we enjoyed the time on the road and at least this project is one I love to do.

Any time I spend in the yard, is like heaven to me.

Thanks again

I can't give you any advice, but I can tell you that my iris, especially the newly planted ones, SINK.... and that's because the soil here on the Cape is SAND... and while I "amend" the soil with plenty of top soil and composted manure, it is still sandy and I finally realized that they start sinking immediately, so while I've planted them on top of the soil, within months, they are below the surface.... I keep scraping the soil away from them, but....

RE: how to tell types of iris

I'm sure glad to hear someone else has had the problem, I was beginning to think I'd gone..not to far a trip..crazy.

If I just try to scrape the soil off, they will be 2 to 6 inches below the surface. Guess, I just have to try sticking new dirt under them.

We were up to visit the Cape late last summer, It was as beautiful as I all ways thought it would be. Hope to get back some time in the late spring.

OK, maybe I should be learning something!

The first thing I would have thought is that the wind--especially anywhere near the beach--was blowing sand in on top of the rhizomes. Do inert objects, such as bricks, tend to sink too?

Iris will survive being planted deeper in sandy soil than in clay soil, but they would be more likely to grow down to the new level, leaving the older part of the rhizome showing at the surface. By your description, the whole rhizome is sinking as if it had contractile roots like lilies, or a few other bulbs.

Question for the true gurus: Does anyone know if Iris do this?

RE: how to tell types of iris

In my case, the iris have sunk. The rhizome is down under the sand. They all have long white looking rootlets coming from the rhyizome.

When I planted them all, or rather most, were in full leaf. The leaves ran from 6 to 7 inches tall to very tall. The rhizomes were mostly three fingers width and about 3/4 of the lenght of my complete hand. They bloomed and were beautiful the first year...Then we started traveling and I wasn't there to see them. Now, most have leaves that are under 7 inches tall. Some have all most completely disappeared...as in the leaf is 3 to 5 inches tall and the rhisome is the size of a quarter. How much of this is due to sinking, bad mulching and/or poor nutrients, I don't know. But it makes me feel like a murderer!! I have given up on some other plants, but hate to do this with these. Especially since East Texas is known for it's perfect iris gardens!

I live on a sand hill, as I said earllier it does slant down towards a swampy area. My iron ore rocks, and the flat walkway pavers also tend to sink. Or maybe the rain splashes the sand up that high???? I do have a gopher and mole problem, but..not over the entire property. At the house we had in town, I didn't have this problem...but then that dirt had very little sand.

RE: how to tell types of iris

At my old garden the soil was almost entirely sand and my irises had the appearance of sinking, but it was in fact the rain lifting the sand. After a rain go outside and look at the fans.

In my case, they would have sand splattered over the first 1' or higher. As the sun evaporates the rainwater, the sand has no choice but to dry and drop down in a pile at the base of the fans.

Things never seemed to suffer from it too badly, but I always scraped away the sand with my hands to expose the rhizomes in the early spring cleanings.

The moles always help to make a mess of things too. But, as you said, they don't work over the whole garden. I'm still pressing new plants back down in the soil at the new place (or lifting them from the bottom of a deer's hoofprint).

RE: how to tell types of iris

Oh, you are SO smart!!! Yeah, I have a problem with the sand bouncing up, even to the top of 5 gallon buckets! And of course, the sand can only drop back down...duh!

Thanks, Guess I'll be out rubbing the sand off and speaking nicely to all my irises from here on out.

RE: how to tell types of iris

We're on sand too, and my irises definitely sink. I think the roots pull them down. I have to uncover them a couple of times each year.

It's great for Japanese that grow rhizomes on top of rhizomes, though, keeps them longer before i have to divide.

RE: how to tell types of iris

It's always nice to know you're not alone! Now, what do ya'll think about should I feed them now as I lift them up to top or just lift and feed later in the spring?
