Not a pretty rose at all in my garden. The blooms are small, ugly, and bright magenta. Iceberg is a standout, I had higher expectations of Burgundy Iceberg.

A primary issue with this rose is finding the right colour. It will range from a paler pinky shade, often having an attractive "water-colour" effect of dark pink/burgundy painted on white, through magenta as you have experienced, into the burgundy-red & then into a stunning deep royal purple (my favourite). You have to only buy when it is in bloom to ensure that you are getting the shade of "burgundy" that you want. I had the ultimate deep rich tone on a standard until a freak wind gust caught it. Unbeknownst to me, the top tie had become undone & the whole wonderful candelabra broke off below the graft. I almost cried, as that shade is so hard to come by.

The color on 'Burgundy Iceberg' seems to vary a lot with temperature & UV - mine are generally deep rich purple from late October to mid-July, but are indeed a very bright almost fluorescent magenta from August to October, and intermittantly in the Spring during high UV days (a potted shrub moved into the shade doesn't turn magenta). All the flowers on the shrub can turn that magenta in less than a day - I need to take a before and after picture to post. In the spring, the ones that have changed color remain magenta, but new buds will open purple again

Well, you have to take into account that Burgundy Ice is a sport of a sport of a sport, originating in a pure white rose. A stunning fact in itself. So, one probably shouldn't be too surprised when the bloom colour recurs in some way to the former sport's colours (brilliant pink and pink, respectively).
I bought my Burgundy Ice when in bloom, and her blooms are of the darkest rich burgundy purple, their luminosity enhanced even more by the near-black stamens. It's so beautiful it nearly brings me to tears.
You should not hesitate to replace your specimen with another Burgundy Ice. When she shows her true colour, I guarantee you will fall in love with her.

Tante Rosa . . .

It's not a question of resporting - it's the response of the color producing cells to ultraviolet light. In Michelle's high altitude Colorado garden, she can expect to get the magenta color consistently, and sadly may go years without ever seeing a burgundy blossom. Her season is short and marked by intense UV.

My problem with this rose is leaf senility - we have a 48 week growing season here, but the leaves last no more than 10 or 11 weeks in direct sunlight, so from June to January (dormant season here is February) I'm plucking off dying leaves every few weeks.

If one doesn't mind the orange with purple effect, it does well in the dappled shade of a pomegranate or other such open tree with a very short leafless season - our pomegranates get new leaves within 3 to 7 weeks of defoliating, Under one, leaves on Burgundy Iceberg can last up to 5 months.

This is very interesting. Another factor to consider when assessing rose colour.

Remember, there is no gene that codes for white pigment - white roses are pigmented with reds (most commonly) or purples but have their color production inhibited.

Here, Iceberg (as do other 'white' roses) becomes mottled with pink after a few days of intense sunlight, the result of the inhibitors breaking down and the newly liberated chromatophores pumping out a little bit of color at the very tail end of their lives.

Burgundy Iceberg has chromataphores for both red and purple, as did Iceberg. When the red inhibitor failed to activate, Pink Iceberg was born, the additional failure of the purple inhibitor created Burgundy Iceberg, expressing pigments that were coded for all along.

The majority of my deeper purple roses (e.g. Ebb Tide, Violetta, Diamond Eyes) have a more magenta expression under hot and high UV conditions,

I uploaded some pictures taken this morning of magenta shifted roses - see Diamond Eyes, Midnight Blue, Night Owl & Rhapsody in Blue.
The first three generally are deep purple, the last a purplish steely blue.

Thank you so much! I know Rhapsody in Blue (neighbours have it), so it's stunning to see it in that colour. In our climate, it's cold blueish purple.
Also, thanks for the explanation of white in roses. Would the oppression of red also explain why white roses get pink spots after the rain? Because these freckles have always been a mystery to me. Are there white roses them that don't get them? I don't mind , just curious. And you seem to know a lot *smiles*
