As Zack says, it sounds like you didn't prune enough to get rid of winter damaged canes.
Exposed grafts will be an issue if the temperature drops to around zero, which it will in Nashville sooner or later. Plant future roses with the graft just underground. With long-shanked fortuniana grafts, plant the rose slanting at a 30-degree angle to the grade so you don't have to bury the rootstock roots a foot deeper than they want to be. Cut off any roots that would project above the surface because of the angled planting.

The main difference in damage symptoms between spider mites and thrips damage is that thrips are usually associated with irregularly shaped white or greyish-white spots distributed mainly along the mid-rib and side veins of plant leaves; while similar symptoms caused by spider mites are distributed randomly on leaves. Found this at http://old.padil.gov.au/pbt/index.php?q=node/13&pbtID=116 In addition, I see the leaf turning bronze colored then looking at the underside of the leaf with a magnifying glass can see small white "dots" moving around. This is the mite.
You will need to use a "miticide" to controll or kill the mites. It is difficult to do and you have to us a regular spray program. Miticides can be expensive, but I found a Spectricide product at my local Ace hardware that works for me.

Just a note on thrips.
The Knock Out family seems to be particularly attractive to thrips. So much so that we can use our Knock Outs as "canaries in the coal mine" to give us an early warning that thrips are around and we should be on the lookout for them on our other roses.

You planted them this year or last year?
Young plants not established don't have the resources (a strong root system, canes containing a lot of stored carbohydrates) to produce their best flowers, just like a 21 year old man is a lot stronger physically than he was when he was three.
Patience! This assuming the roses are getting regular water and are in decent soil and are getting a goodly amount of direct sunlight (6 hrs) daily during their growing season.
One thing exclusive of plant establishment is Thrips--are the edges of the petals brown? If you shake a flower over a white piece of paper you may see tiny brown insects--those are Thrips, a rasping insect that can ruin flowers. The other thing is extremes of weather--a forming bud can be damaged by a sudden near-frost or a nasty heat wave. But the other stuff first.

Describe "deformed".
If they were hit by a cold snap during formation, that can do it. Also, if you mean strange green centers, that's called proliferation (there are threads with photos), and it happens in some varieties in the spring, usually on the very first buds to form.




Best picture: Fame (blossoms stay on the bush for weeks and even if faded they add color to the garden)
Best actor in a leading role: Mellow Yellow (planted front and center, always blooming, "look at me" kind of bush)
Best actress in a leading role: Julia Child (love those bright yellow blooms, bushy bush)
Best actress in a supporting role: Betty Boop (blooms and blooms, never has any issues with mildew, no need to deadhead)
Best actor in a supporting role: Christopher Marlowe (just a small bush, blooms regularly, trouble free)
Best visual effects: Gourmet Popcorn (a mini which really does look like popcorn)
Best foreign language: Yves Piaget (love the blooms on this bush, but sadly, a tree is shading it and it suffers mildew but blooms on)
Best visual effects: Dark Lady (love the blooms, but another mildew magnet)
Lifetime achievement: Snowfire (has been in place well over 30 years in a difficult, hot location. It carries on year after year.)

What about Lavaglut? I do not grow it-- it is on my "next year" list.
I have read and heard many good things about it-- though I'm not sure it would meet your height requirement.
Nor do I know firsthand about JB avoidance, but my experience this year is that JBs go for the yellow roses.
I'm also hearing good things about Europeana...

Hi everyone,
Thank you so much for your reply. glad I asked here. wow. Home Run is beautiful!
I found my local nursery was selling Flower Carpet Rose Scarlet for 20% off. I don't know about this rose so didn't take it. But is anybody growing Flower Carpet Rose?
thank you in advance for your input.


I've seen it win some awards for form. ;-)
Fragrant Cloud has a true exhibition quality to it, and is relatively unique with it's habit of reflexing the bottom petals. Touch of Class is another rose that does that and we all know of its exhibition capability.

i found someone who can do a custom graft. My question is it worth having done for a show prospect? Is the form good enough? does anyone have any experience at all with this rose as far as exhibiting.
It's won several medals overseas but little data exists for US. It's such a lovely looking one.
Any opinions would be greatly appreciated!

Agreed! There are some really great roses that still win once in awhile. Last weekend Cleo HT won Queen. I don't even know where you'd get that one anymore.
Olympiad has done well here too. I hope they continue to recognize great form over the newest craze.
Anyone else have luck with an older rose?

Hi Emsie, If the canes are brown on the bottom, but still green and blooming on top, you should keep those. Only cut out the canes that are dead all the way up.
I'm not sure what zone you are in, but it could be that the rose suffered from black spot and that's why you don't have any leaves. Some of my climbers get like that if I don't spray them. But if you do trim back some of the tips, they will put out new leaves.
You can also try to trim back the lilac so the rose gets more sun.

Buford said it before I did.
Cut away anything that is dead from top-to-bottom.
Keep what still has green coming from it.
What I personally would do with this rose is sit on the ground and follow each of those short canes from the bottom to the top. If they're dead the whole way, remove them as far down as you can. If they're growing something, leave them be.
Once all the truly dead stuff is gone, you can see better.

Have Koko Loko here in Chicagoland(z5) planted last spring and has been a disappointment to me. Lost half the plant (while mounded) over the winter and the colors are just okay to me. Honestly, my ten year old Distant Drums is similar in color but much more hardy and free flowering. To be fair, my Koko Loko is grafted and I don't have much luck with grafted.
Mine is in second year and doing fairly well. Only about 12-15 inches tall. Am hopeful for future. Awesome color and form. DD is taller and more vigorous for me, but the myrrh is not my fave.
