Gardeners' Notes:

This plant has been growing for almost a year in our side yard and has bloomed for the first time with less than a half day of sun. The blooms are dark purple and have a noticeable black licorice/anise scent. The new foliage growth is still sparse and less than robust but the blooms are almost worth it. I'm looking for more vigor and healthier foliage next spring before giving this a positive rating.

I planted this 2 years ago, and while it has had robust growth each year, it has yet to bloom! It has one of, if not THE, biggest clumps of all the irises I planted that year - big fat rhizomes and fans - certainly should have bloomed last year, let alone this year! It is in the same patch with other irises that were planted at the same time and have bloomed the last two years, so it's not the soil. The clump is so big, it really should be divided this year, but I'm afraid if I start all over again, I may never get a bloom. I guess I'll give it one more year to save it's neck.

I will say, I assume it is Hello Darkness, but since I've had quite a few mis-labeled irises from the grower, I'll have to wait until it blooms to be sure it is what it's supposed to be.

Died of bloom out so will try again.

I've tried this iris twice................both times it only survived for 2-3 years for me. Slow grower, then dies. Must not like the southwest desert climate.

Ordered from Schreiner's so should have been the correct plant. But mine wasn't close to black, just a dark purple and definately purple. And the plant apparently doesn't do well here in zone 6a Michigan. I tried it for three years and there was something wrong with it every year. Malformed flowers, rotted stems, or rotted blossums. And for me, and many other members of the local iris club, it was quite slow. All of us have given our garden space to a different and more worthy variety.

I'm growing "Hello Darkness" in Grand Junction, CO, and it looks like the photo submitted by mountaineer-charcoal black. You have to be closer than 12 " and/or looking at it when it's backlit to see the dusky purple sheen. Beautiful, and anyone glancing at it would definitely call it "black".

My plant is really dark. I'm a little color blind so I asked some keener sighted people what they think and they all think it's "Black with a purplish tint". It's a spectacular specimen. The size of the flower is impressive. I stuck this in with my Siberian Irises which was a mistake. I think it needs to be alone or farther removed from other irises because it is such a show stopper. It's unique and it is a conversation piece but I'm not really sure where it would best be featured in the garden. I paid 9.95 for it at a local nursery about a month ago. It has had 4 blooms and a 5th on its way. The first bloom was the largest. I think I got my money's worth.

A lot more purple than black in this one. The pictures schreiners gardens posted had it shown as almost back. The upper half is completely purple. Very nice, but not dark at all.

It has a very nice bud count, and the individual blooms are good.

This 37" early to mid season bloomer was awarded The American Iris Society Honorable Mention '94; Award of Merit '96; and the Wister Award '98. The Wister is the highest award in the tall bearded class.

Hello Darkness is difficult to photograph because it is so close to black. It does have the velvet finish that you can see here and has a lovely fragrance.
