Vine Maple (Acer circinatum) in Colorado Springs

Aha! Got your attention!...Of course, that's not flames but fiery fall color you're looking at. If someone had told me there was a mature vine maple blazing like that in Colorado Springs, I'd tell them "Phooey! We've tried growing vine maples at Denver Botanic Gardens a dozen times: they get a little smaller every year, and eventually die: they're just not hardy". These pictures were taken this fall by none other than Judy Sellers, Board Member of DBG and chair of the Garden and Conservation Committee. She purchased that vine maple at Denver Botanic Gardens' plant sale twenty-seven (that's right 27!) years ago as a small sapling: it has obviously grown and flourished and challenged every truism I would have believed about the hardiness of vine maples. I was frankly flabbergasted when she sent me this image and simply had to share it with you.
Why would a tree like this grow for Judy and not for us? Judy lives near the Broadmoor, practically in the foothills where Gambels Oak is common and soils probably a bit more acid than at York Street. Vine Maples come from the Pacific Northwest, where the maritime climate and acid soils are utterly different from ours. But Colorado Springs is higher, colder and somewhat drier than Denver, so the playing field should be tilted towards Denver. My hunch is that her tree just has hardier genetics, possibly coming from colder areas than those we have tried. I have seen vine maples growing on the east side of the Cascades at very high altitudes where the climate must be very much like Colorado Springs or Denver: those are obviously the ones we need to try growing.
There are myriad lessons in this wonderful tale: private gardeners in our area often succeed with special plants we don't have (or have failed with) at Denver Botanic Gardens. DBG does not have a monopoly on plants hereabouts! And we have much to learn from you. The biggest lesson for me is that I don't know quite as much as I thought about vine maple: it's always worth trying plants you've lost yet another time. And of course the best lesson of all to take from this is buy lots of plants at DBG's plant sale: you too may end up growing something that we've lost at at the Gardens, and just imagine your bragging rights then!

Here is a picture of Judy Sellers in one of her typical wild habitats! In addition to being a long time volunteer and supporter of DBG, Judy is a landscape designer and active environmental steward, prominent in the Nature Conservancy and Garden Club of America, among many other organizations. She has written the text for Colorado Wild, a stunning tribute to nature in Colorado.

Glad to get all of your comments: there should be a special club for us maple fanciers. By the way, despite our nasty cold snap that ruined much of our fall color, the thousands of young Acer x freemanii (A. saccharinum x rubrum) around Denver are truly eye blasting with their scarlet color. Arborists hate the plant, but it has proven to still turn despite extreme cold. I will be intrigued to watch these mature....

You must protect that little maple a bit for a year or two and get it above deer level so we can really find out how hardy it is! You mention provenance: do you know where your's came from? Of course in Wisconsin you have sugar maples galore, so fall color isn't the issue it is with us!

I've never succeeded with vine maple either, but speaking of gorgeous maples, another reliable sight for great fall maple color is on I-70 between mile 70 and the strawberry exit, east of Salina Utah. not vines, i imagine big tooths. usually see them in early october.

It's great to see Acer circinatum get a bit of attention, I forget how much we take it for granted out here in Portland Oregon. Seems like it takes a fresh eye or point of view to remind us of the everyday beauty we see in our own backyards.

O' how I must get up in the cascades this next weekend. I hear the Vine Maples look just like this along the upper Rogue River where we borrow a cabin for overnight stays. The owner asked me to paint an oil for the inside of the cabin. Then they can enjoy this color blast all year long. Glad it found it's place in Judy Sellers garden where you can visit.

Provenance seems to be the key with vine maples, but siting may play an important role too. I have a small one (deer!) in our creek bottom here in northern Wisconsin Zone 3b which has taken exposure to -30F without injury. It is however growing in a very sheltered site on an old mossy log.
