Cream and pink variegation. Quite common, but some branches revert to plain green and they have to be pruned because they're stronger than the variegated ones (last photo). This reversion often happens on street trees grafted high and since it's difficult to prune each tree, most of them are now almost all green. Mine is not grafted, probably from cutting, and was only about 20 cm high when I bought it. The 1st photo is from June 20th, 2020, the other ones taken today, May 14th 2021 :
Brilliant, I'd been wondering what this one was, my mother bought it a few years back but I couldn't remember what it was, it all came back when I saw the above pictures.
Yes, the leaves on yours are younger and show well the pink colour that gave its name to the cultivar. "Flamants roses" at "Parc Floral", flamingo(e)s (not "Flamands roses", that would be socialist Dutch-speaking Belgians, a very rare species <LOL>) : PS : planting the seeds won't give you a variegated specimen. I tried, some of my friends tried, and the seedlings all had green leaves. But as I said, mine is not grafted and I heard that it can be reproduced by cutting. My tree being overgrown, I'll try at different times in the season because I'll prune it drastically next spring so I have plenty of shoots to play with, and I'll let you know if it works.
Do you have a confirmed ID on yours Alain? Honestly it looks like 'Variegatum', but the two are difficult to tell apart. 'Flamingo' is pinker coming out, but only a little. There are a lot of older 'Variegatum' planted in parks in France. 'Flamingo' is I suppose a "superior" replacement, but there's not much in it. Our 'Flamingo' has been cut hard this year in a "last chance", it's not very healthy. It's just back-budding now. We have a couple of younger 'Variegatums', I'll try to get a pic.
I bought it as 'Flamingo', and when it was younger, the leaves were definitely pink variegated. They also show more pink when they're just budding out. I'm pretty sure it's a 'Flamingo'...
I'm sure it's 'Flamingo' then. All of these show much more pink when they're cut back, too. Even 'Aureomarginatum' comes out pink.
