Identification: Help with Maple ID

Hello,

Hopefully someone can help us with ID-ing this maple. We thought it might be a Silver maple, but the flowers don't match, and then, maybe a Norway, but again, there are some features that don't match up.

Thank you so much for the help!

Andrew

 

mistake .

 

Sorry, Chimera, do you mean we've made a mistake in ruling out Silver or Norway?

 

Sorry schroeder, was thinking it might be Acer tschonoskii or maybe A tschonoskii subsp. australe , but they are said to have red petioles so changed my mind.

 

My thought was also tschonoskii. The flowers look right, pic 3 seems to suggest section Macrantha. A picture of the buds would help, or of course the samaras. I have been unable to obtain tschonoskii here so perhaps someone who grows it will comment.

I agree that leaves and flowers look like tschonoskii's but I am growing it and confirm that petioles are red at Spring. Most Macrantha maples have those red petioles......hmm, a new tschonoskii's selection with green petioles?

Maybe the petioles will turn red , some of the young bark looks reddish.

 

Hi Everyone,

I appreciate you're thoughts on this one. If it is indeed Acer tschonoskii, where can I find a replacement that's about the same size (approx 14-16') as the one in the photo? I'm guessing based on your replies that I'm not too likely to come across one.

Out in Chilliwack, I'm planning on swinging by Minter Country Garden store, is there anywhere else that you know of in the area likely to have them?

Thanks again,
Andrew

 

The Shop in the Garden at UBC had some smaller ones a few years ago, if I remember right. Or maybe they were A. tschonoskii subsp. koreanum.

 

Maybe, there seems to be some variation http://f030091.ffpri.affrc.go.jp//f...E.cpwe1?-lay=All_data&-recid=7837&-find=-find

 

Chimera,

In my tschonoskii the petioles, red when they form, do turn green as the season advances and at the end of the summer they are all green, which agrees with the pictures in your link. I have assumed that the pictures shown by Andrew were taken in early spring.

Thanks Gomero, interesting. Have noticed some A. palmatum petioles changing from green to red here.

 

Surely we can expect some natural petiole and bud color variation within the species, depending on exposition, soil factors, climate factors? For example my heldreichii ssp trautvetteri doesn't have very red buds, which doesn't make me doubt (much) it's authenticity.

Of tschonoskii Harris writes: "branchlets are purplish with some white markings, later greyish-brown and smooth; winter buds are purplish and small." He doesn't mention petioles (though other sources do).

For sure emery. Some A. tschonoskii are reported to keep the red petioles till fall, so all interesting.
