I love this rose! I'm not sure why it's not better known?! Although listed as a floribunda, it has better form than most hybrid teas. Flowers are just a little smaller than a HT, with perfect pointy hybrid tea form that is full and holds its shape well, great for cutting. It has a lovely light-medium lavender color and a delicious lemon fragrance that's a Knock Out. It's a very healthy plant with shining leaves, may need a bit of protection in colder climes. I do spray weekly to every other week as needed. I grew it in MD & MA and am going to try it in Fremont, CA. My absolute favorite lavender rose if you could only have one!

Hi Mitch,

I got this as an own-root about 2 years ago and it seems to be a slow starter and kind of spindly. Do you have yours in full sun? I am in Livermore and have it in 1/2 day sun. Any growing tips you have would be most appreciated.

Hi Lizzie,

I should've updated my experience with Shocking Blue in Fremont, CA. Mine also gets 1/2 day sun facing southeast, but hasn't done as well as I'd hoped. It is not a strong grower and the flowers are disappointing. The color is more medium magenta than lavender, the form is more rounded with slightly ruffled edges, and the scent is NOT pure lemon and stingy at that, only slight to moderate. I suspect that it doesn't like the alkaline soil here, but Regan's Nursery told me that it's almost impossible to correct that unless done at the time of planting. I wish I had better news for you. But bare root roses do take up to 3+ years to really hit their stride, and I assume you are fertilizing regularly.
I've found that my favorite roses in MA/MD smell different here, and not for the better. They have more of an anise/black licorice undertone (like Yves Piaget), although on the plus side, the fruity roses which I don't care for, smell better/sweeter. Like the rose, Secret (white shaded pink at edges) which in MA/MD had a hint of fruitiness, here is pure sweet, and one of my top all time picks for Fremont, CA - ridiculously strong grower, disease resistant, moderately shiny leaves, beautiful form & great scent. I haven't found a lavender I like as much. Memorial Day comes closest, scent is lovely, but the pale lavender (a litttle too pale for my ideal) fades to almost blush pink/white as the flower opens. On the other hand, if you like bicolors, Sheila's Perfume (yellow-peach edged pink) is my other top pick for Fremont. Also ridiculously strong grower, shiny leaves, disease resistant, great hybrid tea-like form, flowers like crazy and scent to die for. If you had to fault it, you could say if the flowers had a few more petals, they would open a little slower and last longer, but with so many flower, who cares!
Hope that helps, take care, Mich (aka Michifur)

I live across the Bay from you and to correct the alkaline situation I fertilized once with liquid Miracid fertilizer, especially for some David Austin roses that weren't doing well and it really helped. I have soil that is naturally hardpan and even worse, the tap water ( which for us is from Hetchy mixed with ground water ) these days is alkaline and even foamy and slightly cloudy due to the drought. So I think we will have to watch the pH. Our local water is pH between seven and seven and a half and roses like pH six and a half. Needless to say, I keep praying for rain!

Thank you, Anita, for that tip. I also have rock-hard alkaline clay that clumps in a big chunk Does Mira-acid solution help with more blue color, rather than pinkish?

I can't say. I don't have a problem with roses being too pink or too blue. I know phosphate makes the colors more intense.

I'm beginning to believe that there are several strains of this rose out there. I had to leave my old one in a move, and it was silver-lavender, darkening as it ages. So I ordered a new one last spring, and this one began bloom as a dark plum color, and it finished in the exact same tone. Not one silvery tone on it all summer. The soil is similar. What I also noted, was that the forst one had more intricate foliage, and the second one had more plain foliage. Health and vigor were identical . Looking through the photos here on HMF, also made me notice there are differences. So I do wonder if this rose is prone to mutations.

I've added a few more references but could find nothing more specific about the foliage. Apparently the original rose had reddish filaments and a smooth pedicel. Is the perfume still there? I have altered the seed parent slightly - the patent actually gave two versions.

My first one was very strong and sweet. Like citrus. The one I have now is moderate and rose-like. I noticed this rose has sports, which makes me wonder if it is just not a stable rose. I know that Zorina is not a very stable rose.

The photos Boyed is showing has the foliage like the first one I had. The second one has more plain foliage.

Another idea is that another Kordes mauve got mixed up with 'Shocking Blue'. There are several mauve roses bred from 'Zorina', for example.

Edit: From looking at the newer photos of 'Deep Purple', the new rose that I have matches the foliage, bloom shape, stems, and darker color. I am beginning to think nurseries are mixing some of these roses up..................

Welp, time to change the 2015 breeding entry to "Possibly 'Deep Purple'" x (Ebb Tide x Livin' Easy) LOL. Theyre both fertile, if it is indeed 'Deep Purple'....

After raising seedlings from my second version of 'Shocking Blue', I feel correct in my analysis that the Shocking Blue from Weeks Roses, which is in my photos here, and looks like the rose the user, Boyed, shows, is the true version. The other version, which I bought at Rogue Valley Roses, lacks the feathery foliage, the silvery bloom tone, and the wavey petals. It is a more condensed plant, with rounded foliage, darker blooms, and round petals. But most of all, the seedlings produced are markedly different.

This rose has still been the healthiest mauve HT-like (its classed as a floribunda, but its about the same architecture as Kardinal 85) rose here in the Portland area. Even Neptune can defoliate, under the right circumstances, from black spot, and Shocking Blue keeps on ticking. It does get very minor mildew, though.

So many mauve roses fail =[ but this one does well here.

Ah! Hopefully it will do as well on the E. coast.
Reply #2 of 2 posted 21 APR 15 by Michael Garhart
I hope so! I love it. I lost my old one due to moving, but I bought a new own-root one this year.

Sweet, I was right. I knew this rose had to be related to Zorina. There is an image of the patent on It seems something happened to the record of the patent but there is still an image of the patent available. The image has text stating that Shocking Blue is bred out of seedling of Zorina x Silver Star.
