Here is another posting of Acer rubrum 'Bowhall', with leaves this time. These are in the West End, my neighbourhood, just off one of the main streets. These are listed with this name on the city's database, and that seems right to me.
Here is another West End grouping, on Robson Street, one of the main streets. The city's database lists Acer freemanii 'Jeffersred' (Autumn Blaze TM is how they are listed) and Acer rubrum 'Autumn Flame' in this group. Here are the Acer freemanii 'Jeffersred' And Acer rubrum 'Autumn Flame'. These leaves are much smaller than on the Freemans.
Yesterday ... a wild « big leaf maple « nr Vancouver BC Acer macrophyllum Thé big leaf maples seem more yellow and more leaves this year ??? I noticed in the summer that it seemed they were not afflicted as much as other years with that mildew on leaves - I wonder if that has subsequently helped the brighter more yellow we see now. Acer macrophyllum - Wikipedia
Thank you, Ron. I have only found 'Autumn Flame' written this way, as a cultivar name, including U. of Florida and U. of Missouri sites.
As Arthur Jacobson wrote in North American Landscape Trees (1996, Ten Speed Press, Berkeley) - an example of a publication where Autumn Flame is presented as a registered trademark - even supposedly authoritative sources are frequently not in step with modern commercial designations. By the way if you are going to keep studying and writing about park and street trees I recommend picking up a copy of Arthur's book, even if it is now 23 years old. (In terms of cultivars what it won't have is kinds put into commerce since 1995, but all 3 named selections you have shown here for instance predate this cutoff by a wide margin). Last time I looked Amazon still had copies.
Thanks. I have set a reminder to make sure I don't already have it when I can get back to my bookshelf, when our window replacement project is finished with my unit, maybe not for another two or three weeks. And I've added it to the Plants Identification Written Resources resource file.
Here are two blocks of Acer cappadocicum, Cappadocian maples, in my West End neighbourhood, 1300-1400 blocks of Barclay St. They are listed on Vancouver's Heritage Register - Find a registered heritage building, site, tree, or monument on the Vancouver Heritage Register, moved one block east on the list. They are on both sides of the 1400 block; third and fourth photos are on the 1300 block. I'll make another attempt at some flaming Acer palmatum 'Osakazuki'. This little one is in my neighbourhood. And here is one in Burnaby, on Rumble next to Ron McLean Park. Curiously to me, I am sure this youngster is A. 'Princeton Gold', has yellow leaves earlier in the season, but now they are green. There are a lot of these in the neighbourhood
Here is a nice group in Burnaby, at Ron McLean Park. I think an Acer x freemanii cultivar. Testing out my Vancouver Trees App | UBC Botanical Garden here, what do you think of 'Marmo', similar to 'Armstrong' "with a strong central leader but denser crown, and the leaves with more exaggerated lobing and toothing, resembling to a great degree those of the A. saccharinum parent. … [A]utumn colour is … often more multicoloured - green, scarlet, purple, yellow and orange in varying amounts". Maybe too narrow, more like 'Scarsen' (Scarlet Sentinel TM)?
I'll make another attempt at some flaming Acer palmatum 'Osakazuki' The Japanese maples are previously known - via something like planting records - to be 'Osakazuki'? Or you are calling them that based on how they look to you now? Because there are hundreds of Japanese maple cultivars. And randomly encountered specimens can even be unnamed seedlings.
Yes, just on how they look to me. The Burnaby older tree would have been a landscape plant (planted by the landscaper). I can't guess on the young one in my neighbourhood, but I don't see an older similar tree nearby, so would likely have been purchased from a garden shop.
Thanks. Seeing that, I don't like that ID so much. I had edited my posting to suggest 'Scarsen' (Scarlet Sentinel TM).
I don't see an older similar tree nearby I wasn't talking about spontaneous seedlings, but rather planted specimens. Regarding the cloned Freeman maples I'd want to be comparing with known plantings in person before making naming assignments to found examples. Same goes for Japanese maples like 'Osakazuki', that's why I suggested visiting the one at Van Dusen which - assuming it is correct - could be used to check. Of course, certain selections such as 'Shishi-gashira' are effectively unique - at least in the general landscape of this region - and can soon be identified with confidence once learned. Without checking them against known examples elsewhere.
A couple more pics of Autumn colour. Pics 2 and 3 are Jerre Schwartz. I love it. Pic 4 is from my Ukigumo.
I can't resist an opportunity to share this photo of my glorious Seiryu - the blazing highlight of my wild garden and still only about 10 years old.
This is the best I can do since I can't reach a vantage point higher than the tree. It's close to 12 feet now.
Roger Williams Park in Providence, RI. Ill be posting more soon. I go 2 to 3x a week to catch the colour change. I hate that none of the trees are label.
- Acer p. 'Ryusen' : many of the leaves are burnt at the tip, but still, it's showing lovely shades between green, orange and red. - Three A. p. from seeds: . the first one was from a red dissectum: . the second one looks pretty much like (is from?...) the plain species: . the third one has longer internodes than the plain species and slightly larger leaves. I let the leader grow to strengthen it, then pruned it in late August. It's put out new leaves since - and yes, it needs repotting in a much larger pot ;°)
I mean not only the 'Seiryu', but the wild garden too (^^), and the late sunrays in the last sunny evening before another, week of rain... ;°)
As my friend to the south points out, we finally had a break in the rain, though with heavy winds. More rain on the way for tomorrow and suite, but I got some snaps in during the sunlight. I can't say it's a great year, a lot of trees are just giving up and have already shed leaves without much show. But there are enough exceptions to make it a pleasure anyway. First the lovely pure yellows of Acer cappadocicum. I don't know any maple with a better yellow, although like every tree this year there is burning at the top. The first 3 are the same tree, the 4th is A. cappadocicum 'Aureum', not really as good for fall color but shining in the sun, with A. chingii in foreground. Next are 3 of the always spectacular Acer 'Linearlobum'. This one had severe spring frost damage to the trunk a couple of years ago and I thought to lose the entire top; but it has miraculously recovered. Finally Acer 'Orangeola', a very tough and reliable dissectum cultivar. More to come, maybe tomorrow during the rain I will get to it!! -E
