1978 New Zealand Rose Annual
p102. Nola Murray. Damped Off. When I was less than a raw amateur hybridist with just a few pathetic seedlings not worth a plugged nickel underneath my belt, and with very little knowledge of how chromosomes went about their business, I decided to set the world ablaze by crossing 'Peace' on to Diamond Jubilee. How was I to know that 'Diamond Jubilee' was a difficult seed parent, for who was there to tell me?......
The following year, I repeated my crossing and I lost the hips. But I was learning fast; I knew about chromosomes and I knew that 'Diamond Jubilee' was a 3n rose difficult to use with a 4n unless as a pollen parent......

There are some lovely pictures of this one on HERE and in BOOKS.............for 30 years I tried this one. In No Cal and in Ohio and really the zone did not matter: the leaves were lovely, the bush fat and sturdy, but the blooms! Good grief, so easily rain spotted, generally with vegative centers, often with an ugly green cast, and sometimes no blooms at all, just bush, endless blind shoots.............I give up, I gave up, would love to know some details on how you grew it/grow it from those of you who have posted lovely pictures because this one is one of the worst roses ever in my experiences............

The vegetative centres are due to its breeding, alot of hybrids which are triploid roses do this when they bloom early in the season when temperatures are cooler. As the temperatures increase this defect seems to grow out. I must admit it is sporadic in its blooming, your problem may be due to it growing in a cooler climate . This is a rose which I have used quite a bit in breeding programmes with very good results .

Thanks for the response! I may try it again, like many others when it gets it 'right' it is sooooo right. I did try it in Chico, Ca which is beyond hot in the summer and it did not better or worse then in more moderate yet highly humid central Ohio. Intrigued by how Marechal Niel the tea/noisette figures prominently in the parentage of DJ. When you breed with it do any of the opspring throw back to Grandpa Marchal Niel at all, in any manner?

I dont think the heat worries it that much here in OZ it went through a period of 120F +. Diamond Jubilee's seedlings , whether it was used as seed parent or pollinator, tend to look a lot like DJ. The bloom structure takes on what you crossed it with.

Before the Hurricane, it was the best rose in the garden. Our climate has long, mild winters, short springs and long, tropic summers- general coastal NYC. No fertilizer, rather poor clay in sun and well watered. Perfection every time.

Why add the baking soda for aphids? Water is as effective here for knocking out aphids without adding any additional substances to our already alkaline water. Perhaps the "salt" you had issues with had something to do with the baking soda?

The baking soda also prevented pm or bs on the youngest growth. After it hardened off, the leaves were immune. The salt was from Hurricane Sandy's floods. The subsequent snow storm probably didn't help.

I sincerely doubt many, if any, roses are sufficiently "salt tolerant" to withstand being inundated by such a marine storm surge. Those which have survived, did so probably due to other mitigating circumstances than simple "salt tolerance". Ironically, an own root Diamond Jubilee proved to be one of the most oak root fungus tolerant/ resistant roses in a friend's garden here in California. It existed for many years, smothered in a sea of "Honey Fungus" mushrooms while many other plants (including roses) up and died.

Sorry, the original post was

I used to grow this rose, but it is NOT salt tolerant. It was very healthy with very fragrant blooms that unlike some yellows faded gracefully. I do not spray, except for baking soda solution in April to knock out the aphids.

I accidentally deleted it, and it is not undoing itself.

My favourite rose. If I was allowed to have only one rose this would be it. Simply glorious colour, and shapely buds that open slowly into large beautiful flowers with a lovely scent. The plant is completely healthy and vigorous. Excellent as an exhibition rose.

One of mine too, Rosalie. I am always blown away by its parentage.
