It's Been A Good Year For Budding!

I consciously rooted both long and short root stock pieces of Virus Indexed IXL, Virus Indexed Fortuniana, Cardinal Hume and Pink Clouds last year and this, using the "Burrito Method" detailed here in earlier posts. I intended to create patio standards of polyanthas and some of my seedlings using the longer whips of the IXL and Cardinal Hume. A few of these have been budded this summer, but several have been used to maximize my chances of success budding varieties I wanted to make sure I succeeded in adding to my breeding stable. I inserted up to fifteen buds of the same variety on a long whip in hopes several would take. It has worked! The goal wasn't to create a garden plant from the longer whip, but to establish the variety and generate more propagation material from the initial buds. Once they are well grown, I also intend to cut the longer whips apart and attempt rooting them with the scions already successfully budded to each shorter piece of root stock. 

I decided to only use The Chip Budding Method Burling Leong of Burlington Roses uses as it is the fastest and easiest budding/grafting method I've seen. It has been remarkably successful this summer! Several varieties were budded on both Pink Clouds as well as the Fortuniana so I can plant them near each other and compare their performance. 

I thought it would be fun to share some of the more dramatic results here. So, here goes!

This is a crested seedling a fellow member of the Rose Hybriders Association raised from Tournament of Roses and Crested Jewel. This was budded to both Fortuniana and Pink Clouds on June 4, 2014.

This is the Fortuniana plant. 



It expresses a significant amount of cresting which I hope to mine for further breeding.

The same crested seedling also budded on June 4 to Pink Clouds.
I realized in the twenty-one years of her life, I'd never attempted to bud Annie Laurie McDowell, a failure I needed to remedy. Annie Laurie McDowell, budded on June 16 to Pink Clouds.


Annie Laurie McDowell budded on June 16 to Fortuniana. 
Ironically, the foliage of the young, budded plants aren't quite as deep green as the own roots. Perhaps the extra push the stocks provide requires heavier feeding than the own roots demand?



Not all pushed as quickly, as this Annie Laurie McDowell bud on Pink Clouds, also from June 16, demonstrates.
 This Annie Laurie McDowell on Pink Clouds wasted no time in pushing. 

 I also tried buds in several different stages of development to determine how they might react. This is a quite immature bud of Annie Laurie McDowell on Pink Clouds from June 16. It has successfully knit to the stock, but will require more time to mature before it begins to swell and grow. 
 A more mature, slightly swollen bud of Annie Laurie McDowell wasted no time developing on Pink Clouds. (June 16)
 C04, a crested Moore hybrid, which isn't a very vigorous growing plant, budded to Pink Clouds on April 28. I didn't head the stock back until just a few weeks ago, worrying perhaps the buds may not have knit, but they all took and are now pushing growth. Many of the stocks healed themselves and stopped "bleeding", but several refused. I attempted sealing them with Elmer's Glue, which did work on a few, but those which pushed high sap pressure, dissolved the glue and continued weeping. A few drops of wax from a cool melt candle, not hot enough to damage the plant nor burn my fingers which I accidentally dripped the melted wax on them, took care of the problem on all but two or three. More wax is obviously required to seal the wounds from the tops being removed above the buds. 

 Golden Angel X CA Nana is a Moore species hybrid I wanted to test as a budded plant. Several buds were inserted in this longer IXL whip. It seems all have taken but this one really took off! This is the growth since the buds were inserted on June 19! This flowering branch would be called a "maiden" if it was the single bud grafted to the stock. To produce the branched bare root we're all used to, this initial stem would be pruned back to encourage the two guard buds (one on each side of the primary bud) to begin growing, producing the branches we expect to find. 


Centre Stage is an extremely prickly, crawling, creeping "shrub", I thought might make an interesting shorter weeping standard. Here are it buds on a three foot Cardinal Hume whip, budded on June 17.

 A dear friend had lost her Noisette, Cinderella to gophers. I knew one person who still grows the variety, so I begged some bud wood year before last and created a budded plant for my friend, which I delivered to her last month. She felt quite a bit of pressure knowing there weren't any back-up plants in case something happened to the one I propagated for her. I budded five Cinderella buds to this IXL whip on July 8. All five have succeeded with three already pushing growth. 


 Not all the insertions are as elegant as some and not all are as eager to grow, but at least they are alive. This is Climbing Columbia, inserted into Pink Clouds on June 14.


I promised another friend I would try budding Eugene de Beauharnais to Fortuniana for her. That can take a while! First, the stock has to be rooted, then the budding occurs. It's already been over a year since I made the promise. I hope to be able to pass the plant on to her later this year. This was budded on June 19. You may notice I inserted two buds into this stock. If only one had taken, the plant would be fine. Since two succeeded, it should become fuller, faster, or I could cut them apart this winter/spring and try rooting the top bud individually. 

Eyes for You budded to Pink Clouds on June 7. This wasted NO time in pushing new growth! I wanted to bud Eyes for You on Fortuniana, but I was limited by the gauge, the thickness of the material I had to use for stocks. You can put a smaller (narrower) bud on a thicker stock, but not vice versa. I had pieces of Pink Clouds greater than thumb thickness while Fortuniana failed to generate anything thicker than a # 2 pencil. 
My final budded Grey Pearl has threatened to commit suicide for the past two years, so I figured it was now or never. This is Grey Pearl budded to Fortuniana on June 7.


And to Pink Clouds on the same date. 
 Lilac Charm grows OK own root, but nothing to write home about. Here is a double budded Lilac Charm on Pink Clouds, budded on June 16.

 Manhattan Blue is one of several varieties of bud wood I received later this summer. Several buds were inserted into this IXL whip on July 1. Nearly all are already pushing!
 MORcrest is the first of Ralph Moore's crested breeding roses. It is not a strong plant own root. The plant from which this is budded is own root and hasn't put out more than two inches of growth per year the past several years. It had one flower on it this year. The multiple buds inserted into this stock were budded on June 17. There is far more growth from these two buds than from the entire own root plant in the past two years. No exaggeration! 

 MORsoul is a Soulieana x mini cross Ralph Moore created and never released. Its other name is String of Pearls. It grows like a ground cover, making it another interesting candidate for a shorter weeping standard. This is about a three foot whip of Cardinal Hume into which several buds of MORsoul were inserted on June 20.



Moser Striped is the possible Rainbow, the striped sport of Papa Gontier, though a more vigorous version, from The Sacramento Cemetery. I'm not happy with its meager growth as an own root plant in my conditions. This is the more vigorously growing budded plant on Pink Clouds, budded on June 14. Particularly for standards and weaker growing types, using multiple buds can more quickly result in a fuller plant. And, should one not make it, can save the stock and prevent having to attempt re budding it. I only put the same variety on the stock used for it previously if I have to attempt re budding. The chances are many of these roses are already virus infected. By only using the same variety on the stock upon which it was previously budded, I don't run the risk of passing any potential virus infections around. 

I've tried rooting R. Primula before, unsuccessfully, but the multiple buds I inserted into this IXL whip on June 19 have all succeeded with four already pushing new growth. 
My own root Tom Brown has generated almost six inches of growth and put out six flowers this year. I hope these buds on Pink Clouds from June 7 will perform significantly better!

 Yann Arthus-Bertrand, another variety I obtained this summer, also with multiple buds inserted into a longer IXL whip on July 1 and beginning to push. 
There are quite a few more which were budded three weeks later, I'm waiting to see perform, as well as many from earlier budding that are green but not doing much yet. 

The "tricks" have been keeping the stocks well watered so they keep pushing a strong, steady flow of sap and making sure to match at least one point of cambium on the bud to that on the stock. Out of a bit over 140 buds since June, only 17 have absolutely failed. That's an almost 88% success rate at this point. Not bad for being rusty at budding and the weather extremes and severe drought we're experiencing. I can vouch for Chip Budding being the easiest, fastest method of grafting I've ever encountered! If you've been considering trying budding, start rooting your stocks now so when summer hits next year, you are all set. It's much easier than you think!

More fun "discoveries" from a lovely, sunny, "cooler" Sunday morning...

I've been making "out there" crosses for years. Many "what if?" combinations have been generated with many either returning few decent results, nor none at all. That can be frustrating, but also inspiring. I'm sure you're familiar with the old saying, "If at first you don't succeed, you need a bigger hammer!" That's pretty much what I have done. Collect much more pollen of the desired "fathers" and more heavily pollinate the desired "mothers" and it appears to have given some promising results. These are all in the seed tables. The crosses were accomplished in 2013 and all have germinated since planting last December, making the oldest seedlings about five months old. 

Pretty Lady is an extremely healthy plant in my climate. Fortunately, it's also very fertile, both as seed and as pollen parent. The stated parentage includes R. Davidii elongata  which has helped give Baby Love, then Pretty Lady their increased black spot resistance, at least to a number of black spot strains. It isn't a cure all for black spot, but definitely the beginning of building improved combinations of black spot resistance. 

One of the crosses I made which honestly excited me resulted in these lovely seedlings. Pretty Lady X 1-72-1Hugonis produced this lovely foliage. 


I know they are actual crosses between the two parents as the seeds were harvested from Pretty Lady. The color, leaf shape, texture and prickles all point right back to the Hugonis hybrid parent. The foliage is very healthy in a difficult situation of trapped humidity within the seed table. When the sun shines on the box, it is direct, extreme and intense. Even using a moisture control soil, it can dry out quite quickly and the seedlings can fry to death, but these are remaining healthy, vigorous and beautiful. None have flowered yet, so I have no idea what coloring nor flower shapes to expect, but pretty much anything in the white to pastels should be possible. 

IHTxLB is a Robert Rippetoe Banksiae hybrid he shared with me several years ago. Robert has some lofty breeding goals and has created some beautiful, incredibly imaginative seedlings. I love the deep purple, single flowers; the healthy, dark, bluish-green foliage and the open habit of the plant. Fortunately, it is very fertile and has accepted a wide range of pollen. 

This seedling is also a definite cross between the two parents. The seed parent (mother) combines International Herald Tribune, a rose I imported from the Harkness Nursery back in 1984-85. It figures prominently in almost all the dark purple roses introduced in the past fifteen plus years. International Herald Tribune contains genes from R. Californica, the California native species rose; and several purple, orange and yellow Hybrid Teas and floribundas. The pollen parent for Robert's seedling was Lila Banks, a result of his putting pollen from a friend's creation named "The Monster"  on Lilac Charm, a British mauve floribunda introduced in the early sixties from LeGrice, and supposedly also containing R. Californica genes. IHTxLB combines Old Blush, R. Banksiae, R. Californica, a few doses of Grey Pearl, orange, yellow and various mauve modern roses. The pollen I used was from R. Fedtschenkoana, with its wonderful silvery-turquoise foliage and "ghostly" white flowers. You can definitely see the Fedtschenkoana prickles and foliage in this seedling. With any luck, it might even have mauve, to (hopefully!) purple blooms and might even offer some repeat. 
The Towhees, a native, "pain in the ear" bird, found digging up the soil in the seed tables irresistible, so I've had to leave the screen cover on this table a bit too long. This and several other overly vigorous seedlings have grown through the screen. I will have to cut openings in it to permit removal without damaging the plants. You can see the definite Fedtschenkoana influence and this one is absolutely vigorous! 

Another in the same table, also suffering from having grown up through the screen is a cross between the white sport of Secret called Secret's Out! and R. Fedtschenkoana. Again, the Fedtschenkoana character is obvious. I know this is a definite cross. 
Cal Poly can pass on yellow blooms as well as significantly reduced totally prickle-free seedlings. This is Cal Poly X 1-72-1Hugonis. When using the more modern rose as seed parent, you may not obtain quite as full a cross due to potentially mismatched chromosome count, and it's more possible to create triploids, three sets of genes rather than even numbered pairs, which might result in reduced fertility, but definitely not always, but it's tremendously easier to determine if the seedling is an actual cross instead of a self seedling. The Hugonis character is obvious in this seedling. From the lineage, I expect the flower to be some shade of yellow. 
Normally, I would not have pollinated Cal Poly with 1-72-1Hugonis because it represents a double dose of 1-72-1, which might result in more of a climbing habit. 1-72-1 is a cross of Little Darling, which can be rangy, and Yellow Magic, a semi climbing yellow miniature. Cal Poly is more dwarf and bushy, but has sported to a climbing form, so climbing plants are possible. 1-72-1Hugonis is a tall plant. Hopefully the more dwarf, bushy genes predominate in this seedling, and the introduction of the Hugonis genes helps dilute the doubled Little Darling and Yellow Magic genes. Hugonis is definitely "in there", as evidenced by the foliage shape, texture and color as well as the prickles. 

This seedling has been stunted by the screen the previous seedlings have grown through, but it appears to want to be taller. It resulted from Pink Petticoat X R. Fedtschenkoana. Another obvious actual cross as evidenced by the foliage and prickles. No flowers yet, but they could be anything from pinkish-orange tones all the way through white.

 Fedtschenkoana has the ability to bleach out flower pigments quite easily, which is why I continue searching for the darker flower on the silvery-turquoise foliage. So far, the best result has been Paul Barden's Fedlav-01, his cross of my Orangeade X Fedtschenkoana seedling with Midnight Blue. My own seedling using DLFED 3, the mossy Dottie Louise X Fedtschenkoana seedling with pollen from Blue for You, resulted in a plant with lovely silvery-turquoise foliage, but none of the violet tones hoped for. Midnight Blue did appear to help remove the "mossing" from the buds as they are completely smooth. 


 It appears to be fertile as it has set large, red-orange hips. Whether there are many or few seeds, or even if any seeds present will germinate, we shall see next year. 
Not as easily seen due to the screen lid being stuck on the seed table until I cut holes for the other seedlings to pass through, this seedling between Golden Angel and 1-72-1Hugonis is the one I'm really excited to see mature. Golden Angel has a great ability to pass on the character of the pollen parents used on it. Take a look at Ralph Moore's Golden Angel X R. Californica nana hybrid. My hope is this might produce a more dwarf, hopefully repeat flowering Hugonis hybrid without the drawbacks of the doubled genes the previous Cal Poly X 1-72-1Hugonis seedling may express. 
This cross was made with the intention of adding the Fedtschenkoana foliage to the violet bloom. It's difficult to determine how much of a real "hybrid" it is and how much of a self crossing it might be as I've not raised seedlings from Werner von Blon until this batch. This is a relatively recent (1993) polyantha from Germany. There is no stated parentage nor are there any documented offspring. This seedling does demonstrate a different foliage texture, color and petal width, texture and color from the seed parent, but little of what I would have through Fedtschenkoana should have provided. I'll have to watch it to see if the species character becomes more apparent with maturity. So far, I do like the results! I've not detected enough scent to determine if any of the "Linseed Oil" scent from Fedtschenkoana is present. 



In a previous entry, I posted about the Pink Petticoat X 1-72-1Hugonis seedling which flowered for the first time this past week. This is its sister seedling. It is definitely a hybrid between the miniature and species hybrid, but it isn't expressing the hybrid vigor of the sibling. I've had to move the plant to the front yard where I can better protect it from the severity of the western, afternoon sun. The growth is still too thin to endure hours of relentless sun. Perhaps with some maturity it will become less susceptible to being fried in weather extremes? We'll see. 



I find the blue tones of the foliage and reddish bronze of the new growth and prickles more attractive than those of the larger, huskier sister seedling. 

Lynnie X R. Arkansana "Peppermint". This cross was meant to see if Peppermint's stippling might express itself in its seedlings. 
The next two Springs are definitely going to be fun!
