  Part 1- Hybrid-tea Roses

'Veterans Honor' a Hybrid Tea rose             Click on Pictures to Enlarge

Above, the bloom is almost normal sized, to the left of the bloom are chlorotic leaves that are subsized; at far left is growth on a cane not yet affected by RRD.

Figure at right. Veterans Honor later in the season, aberrant growth has been removed through the season. Canes continue to sicken with subsized chlorotic leaves and epinastic leaves on new reddish purple canes.

   


'Crystalline' a Hybrid Tea rose:
  
The first bloom is normal , the second and subsequent have sepals much longer than the shortened petals, the leaves on this cane have a 'pebbly' surface, and there are starts of powdery mildew. The red rose in the background is on a seperate bush of 'Veteran's honor'. Note the leaves on a cane of 'Crystalline' just below the red bloom in the picture. Also in front of metal tag in center of picture.

'King's Ransom' below- a Hybrid Tea Rose;
 
In this rose leaves are almost absent, four extremely thorny canes emerge from a single less thorny cane.  This rose is the only rose affected with RRD in the middle of a garden with over fifty roses.  It was the result of a single mite's random landing.  There were taller roses in the garden, but the mite was dropped by a gust of air on this bush.  After this rose was rogued out in spring 2002, 'New Dawn' and an additional HT sickened with RRD in that garden fall 2002.

  Part 2- Old Garden Roses

Old Blush - a China:  
Up in the air, it's witches' broom on a handsome bush of Climbing Old Blush that developed contorted growth that sickened and died between Dec. 1 2000, and late May 2001. This may represent a hypersensitive reaction to RRD infection; other roses in the same garden lived with RRD for over seven months before being rogued out without dieing. This growth blackened with death, the color isn't gray, but black.  

                                               
Lucky Bush:
    

In the left hand photo, several thin canes  of 'Paul Neyron' (lower left) grows directly below massive RRD-infected R.multiflora (upper right side of the photo).

More RRD-infected multiflora is seen in the photo at right, about five feet to the right side of the photo at left.  From the advanced stage of infection of the large bushes of R. multiflora, that 'Paul Neyron' has survived at least two years of exposure to nearby RRD.
Other roses nearby ('Sombreuil') did catch RRD.


Many roses in the vicinity had died of RRD, others were sick with early symptoms. (In other gardens,'Paul Neyron' has proved susceptible to RRD.) This multiflora was at the back of a suburban lot in Watkinsville, Georgia, at the time Rose Rosette was not known in the area.  

  Part 3- Miniature Roses

'Janna' - a mini

Miniature roses aren't immune to Rose Rosette.  These bushes of the Ralph Moore mini 'Janna' had been planted in summer of 2000.  Spring of 2001 found them covered with blooms that matched the label that came with them.  They had been planted together and were healthy.  By October, both were sick.  You see symptoms that include chlorotic leaves, mosaic patterned leaves, subsized leaves, and blooms that have different form as well as 'wrong' colors and the blackened dead canes.  MRXI described the blooms as pink with a white reverse.  This is one of the few instances where RRD led to a darkening of the colors in the rose petals.

  Part 4- Climbers (that aren't in other catagories)

'New Dawn' - a climber
'New Dawn' ( and it's parent plant 'Dr. W. van Fleet') climbing roses are perhaps the most popular climbers in much of the USA.  Many lists of desirable roses have featured 'New Dawn' and growers have responded by adding it to their gardens.  Unfortunately the size and mass of 'New Dawn' make them very susceptible to RRD infection.  These almost unrecognizable blooms on 'New Dawn' show blooms emerging from buds in which the receptacles are all but non-existant. Petal sizes are subsized and blooms will not open.  Leaves are also subsized.  (Atlanta, July 2001) Early spring symptoms of RRD on 'New Dawn' will include witches' broom along the canes, distorted leaves and leaf colors that stand out as wrong.  The size of 'New Dawn' works  as a wind baffle to trap the mites that can carry RRD; the density of the mature plants make recognition of the disease more difficult when only one or two canes are involved.


  Part 5- New Garden Roses (Shrubs &Florabundas)

'Bonica' - a shrub

In this garden in South Carolina, a large bed of 'Bonica' had blooms that were not opening with the look of other 'Bonica's in the same bed.  Curators tried to cut the diseased canes back below the aberrant growth.  On these two bushes about five feet apart, their subsequent growth remains aberrant with symptoms that are common to RRD.

Sadly, Epstein and Hill had used 'Bonica' in field tests and had found that RRD did not infect their plants of 'Bonica'
in Iowa, but that 'Bonica' could be graft innoculated with RRD (Epstein,Hill, and Nutter1997).  Conditions are different from their field studies in this well watered and fertilized garden in South Carolina, and these 'Bonica' are sick with RRD.

'Sweet Inspiration' - a shrub
 

 At left are healthy plants of 'Sweet Inspiration' in Cheekwood garden  in Nashville TN. The one at right   (in the LMU garden in 2000) sickened with blatant reddish purple new growth.  Both the green (presumably healthy canes) and the reddish canes produced blooms in late fall, and both colors of canes regrew Spring 2001. (This is a closer view of the rose at center Chapter 1, fig. 7)  


'Carefree Beauty' - a "Buck" shrub:
At left, normal blooms of a healthy bush of Carefree Beauty from near the dairy at LMU, spring 2001.

At right, is a bloom from the same cultivar, Fall 2001.  Note the elongated sepals, the weak colors of the petals, the petals that remain turned backwards (prematurely reflexed), unlike the flat smooth petals of the healthy blooms.


                                        
Scarlet Meidiland - a big shrub:
A cane cut off with permission of the grounds' crew at the Atlanta Botanical Garden. Note the increase in caliper (diameter) of the stem (thorny) that grew from the relatively smooth original stem.  A penny for scale.     The hedge of Scarlet Meidiland after winter pruning is blooming again. A spray of healthy blooms is shown below.

                 
The bush next to the cane
pictured in second photograph (with an enlarged caliper growth on it) after puning hyperthorny canes emerged, implying the entire bush is infected.  Infection was first seen on this bush in late Sept 2000.  Had the canes been cut at that time, the bush might have been saved, but waiting until spring doomed the bush and probably surrounding
bushes.


'Red Meidiland' - a small shrub:

Above - new witches' broom emerging along a cane
Below- a bloom that represents reduced petals and distorted petal color. Upper right notice the mahogany reddish terminal growth is followed by chlorotic stems and foliage (even though the foliage is aberrant in shape.)
Red Meidiland growing beside a city street in Atlanta GA. Part of the bush had been sick for at least a
year when these photos of contorted blackened (now dead growth) were taken(bottom photo).


'Constance Spry' - a David Austin Rose


In Watkinsville Georgia, many canes of this 'Constance Spry' bloomed with normal blooms, but others had bud-less growths emerging from single leaf axils.  This rose is in the same garden as the "lucky 'Paul Neyron'" above, with the very massive infected Rosa multiflora along the back property line.





To right is an enlargement showing hyperthorniness on canes of 'Constance Spry.'



'Queen Nefertiti' - a David Austin Rose
The Cane distortion at left is the key plus the subsized leaves compared to the rest of the bush.


'Gertrude Jekyll' - (below)another Austin Rose
Figure at left - late stage infection with a single parthenocarpic hip (with fused sepals) and subsized leaves with a second parthenocarpic hip at left center  In this hip the sepals were joined together through half of their length.  Earlier, hyperthorny canes were removed from this bush by cutting them off where they joined the apparently healthy canes.  The disease continued to reside in the asymptomatic canes.  By this time, the bush no longer had the energy to put out canes, but produced rosettes of subsized leaves.


'Charles Austin' - an Austin Rose - caught at earliest stage of infection in fall.
At left a typical spray of 'Charles Austin' blooms in early fall in my garden. At right, the first sign of Rose Rosette on the same bush, late fall 2001.  We think we saw this within two days of first appearance (based on the size and speed at which we believe the disease develops after innoculation by a mite bite)  and we cut the cane back as close to the ground as we could (about five feet below this apical aberrant growth).  So far, growth  has been normal (January 2007). We continue to watch this one, especially the area where this cane was removed.


                                   
  Part 6- Polyanthas and Floribundas

'The Fairy' a polyantha:
The reddish new growth is the key to RRD in this heirloom bush. The reddish leaves are extremely thin, and associated buds are not in sprays, but had fasciated stems.  This reddish color is totally foreign to 'The Fairy' in fall
growth in east TN.  This was the family's beloved rose; fortunately they had shared it with other family members.  



'Sunsprite' - a Floribunda
Skinny somewhat chlorotic leaves are symptoms of RRD; this yellow rose no longer has petals that are clear vibrant
yellow, but has petals that are mottled and pale.  Bloom form has changed as well.



  Part 7- Species & Their Hybrids

'Ipsilanti' - a Gallica rose:
                
On the left is a bloom on the healthy very large plant complexand on right is the infected area. At right, the southern end of the same bush, badly infected with RRD.  Powdery mildew coats the leaves and stems,
canes are contorted, and blooms are subsized and have fewer petals than healthy roses. The photo is further confused
by Honeysuckle wrapping around the bush. In Washburn TN, five houses away a second plant is not sick with RRD
nor are eight additional roses in that latter yard.


'Seven Sisters' - a Multiflora Hybrid:
           
Healthy blooms and foliage of Seven Sisters Note the red edge on the leaflets in the picture above compared to an earlier photo of same plant on left. Also, the leaflets are now more pointed. Note the veining in the picture above and a leaflet growing out of the badly deformed stipule. In the above picture, you have a stipule growing along the entire length of the leaf

                     
'Pink Grootendorst' - a Rugosa Hybrid:


A large bed of this cultivar grows near the old dairy at LMU.  RRD infected multiflora adorns hillsides surrounding
the dairy.  In late fall 2000, canes of Pink Grootendorst started dieing; the dead canes had one or more swellings  but
there were no signs of burrowing insects in the canes. The swellings may still have been the result of cane borers.
The following spring the bushes looked healthy.  Their proximity to the garden with RRD and to the wild roses with
RRD suggested that these roses deserved watching and in Fall 2001 a typical witches' broom emerged from a single
bush.  The subsized leaves below, the comparison of a healthy leaf (left) with a sick leaf (right) shows the difference is
size and relative dimensions of the stipules.  The sepals on the rose cane with witches' broom also were larger and
overgrown when compared with 'healthy' sepals.  We removed the cane with witches' broom and winter 2007 growth
on the bush showed no signs of RRD.
