This is not a question.
Douglas Justice did a write-up and photos on Akebonos for the April 6, 2007 Botany Photo of the Day, so thats where to find out about those.
One thing to add: This cultivar is often confused with Somei-Yoshino. Some distinguishing features are listed under the Somei-Yoshino thread. Somei-Yoshinos have not been planted recently in Vancouver, so it's a fairly safe guess to call young trees that look like this Akebonos.
Here are some autumn colours, three trees in a row perpendicular to the English Bay seawall. One has not turned yet, one is completely turned, and the third is two-thirds turned, one third completely green. I thought when trees were grafted that they put a top on a different bottom, but it looks like this might have been two or three tops grafted on? It's beginning to dawn on me that trees have individual differences just like people do, so trees of the same cultivar can develop at different rates, but this would be like one arm developing differently from the way the other arm develops. The green leaves in the first photo looked like the yellow leaves - it didn't seem to be rootstock growth.
Here is an ungrafted Akebono youngster that has quite a different habit from what we're used to seeing. It's growing straight up with what looks like a single leader, the way Aviums do, but it has an Akebono label (thank you Parks Board) and is budding out now like the other Akebonos in the city.
Here are some more West End young Akebonos that seem to not be grafted. The locations are in the file names you see when you mouse over the photos.
How much variation can there be in these things? I'm going to use Douglas's words from the Kanzan vs Pink Perfection posting to haunt him:
I think it's really important that people try not to be "absolute" about anything, particularly biological systems. Better that through familiarity and close observation, we get a better understanding of "die gestalt." Agreed, we need information to initially differentiate the various cultivars before we "get it." However, we have to keep in mind that the information we're given may sometimes be misleading or even wrong.
All I'm going on now to identify Akebonos is that staminode (extra petal thing in the centre of the occasional blossom), but Kate, in the Strathcona posting (the one that comes up and the following one), and today David Tracey, on our walk, remarked on how different some young trees look from the older ones that I've been claiming are the same cultivar. Here's a photo of a tree that David says is not likely to spread out, but it has Akebono blossoms. Sorry about the brilliant (not) camera angle - I hope you can see that it's very upright - the wispy bits to the side are from a tree behind it). I posted a younger one that shape in the previous posting here, which came with an Akebono name tag.
"Die gestalt" says "different tree". What gives? Are these all Akebono? Are there new and improved Akebono that just don't get a new name?
Note my posting on April 18 last year, of the young presumably Akebono with the very upright appearance. Here's a young tree I saw yesterday (March 6) with a very horizontal appearance. This is the shape I think of for older 'Akebono'; young trees do seem usually to be more martini-glass shaped.
The number of petals is more variable than I'd thought. This 'Akebono' has lots of blossoms that seem almost double, with extra petals as well as staminodes, but on other trees we saw today that I swore were 'Akebono', we had to look hard to find a single staminode, and no double blossoms at all.
I've heard a lot of talk lately about how 'Somei-yoshino' look white and 'Akebono' are more pink, and that's how to distinguish them. Sorry, that won't work. In the Akebono vs Somei-Yoshino thread, it does say as much, but there's not much mention of that here.
What does seem to be the case is that when 'Akebono' are open and pink, nearby 'Somei-yoshino' are white. In spite of what I said in that thread I linked to above, I think that's primarily because the 'Somei-yoshino' open about three days earlier than the 'Akebono'. As well, 'Somei-yoshino' turn white more quickly when they open than 'Akebono'.
As they age, though, 'Akebono' do turn bright white. In the first photo, the middle tree (it's quite a ways toward the back) is 'Somei-yoshino' and the other two are 'Akebono'. The trees in the next two photos are 'Akebono'. Where the 'Akebono' have been open for several days, they are entirely white.
What happens next is that any 'Somei-yoshino' blossoms that hang on the trees will start to get pink centres before the 'Akebono', so the more white trees will be the 'Akebono'.
Here's an example of a very pink-looking 'Akebono' just opening, on the SW corner of 16th and Marine Dr. I walked all the way over there (well, across the street, but it was a complicated street to cross) to see what I thought was a new-to-me pink pendula sort of tree, so was actually disappointed to find that it was just an 'Akebono' that seems to have had a hard life.
On the other end of the colour spectrum are the 100 young 'Akebono' trees at David Lam Park, which I posted in the Downtown blog. There are a few trees that were still very pink, as seen in the background here, so I was convinced all the others must be 'Somei-yoshino', but they're really 'Akebono' too.
