    Fall color photo: 11/10/05

    The spring color is quite nice on this plant, but the summer and fall color have not been outstanding. Maybe others have got better fall color. This plant is very rigid in its growth--I am not sure if I like it or not.

    Hi Mike,

    You mention that the summer color is not so great...does this plant behave similarly to Red Dawn. ie. does not hold it's red color well? And do you think that yellow was/is the predominant fall color for johnin?

    Hi Robert,

    I would say that Red Dawn holds its color better in adequate sun. As for Johin, after I have thought more about it, the plant behaves much like, if not identical to, Palmatifolium. The difference being that it starts out red. This plant has had some nitrogen late in the season, so the complete yellow fall color might be misleading, but I suspect it to change very little and maybe have some oranges come up like Palmatifolium. The two plants for me have had identical fall color.

    MJH

    Just a spring update. I still don't know what to think of the plant, but it is rigid in it growth habit.

    Hi MJH,

    I grow a plant that is tagged 'Johin". And I have a A.S. 'Palmatifolium'. You mentioned in this thread the similarity between 'Johin' and 'Palmatifolium'. Do you find that the growth rate is similar? Also do you find that they are alike in being "very rigid in its growth"?

    The 'Johin' I'm growing is not like the examples pictured. Wondering about its identity.

    Thanks

    I'm very interested in this cultivar, but I'm wondering about the colors. In Vertrees' the pictures appears as though the leaves are more of a rusty red color rather than the more purple tones of these pictures. Is the picture in Vertrees' more correct?

    Jalf,

    Sorry i don't have a pic. My plant must be wrong. It is not red at all mine looks a lot like A.S. 'Microphyllum'. Maybe it will change up this year but I've had it 2-3 years and it's been elegant, rigid, very slow and green.

    It's a pretty easy one to locate for a good price so I might try another.

    here is the color in the first part of august. The color is very nice, its growth habit is not as popular.

    This is Acer Shirasawanum ' Johin' the darkest of my Shirasawanum's. I was not sure about buying this cultivar, but after a couple of seasons in the ground in morning sun and full afternoon and evening shade it looks rather special IMO and I'm glad I did purchase it.
    I have attached Spring and Summer photos and you will see the lovely bronze colouring. Later in the Summer it does turn to a nice dark green with those hints of earlier bronze on the outer tips.
    I fully reccomend this cultivar.

    An update on my Johin, another Shirasawanum that has done very well after the very strong winds of the beginning of July 2020.

    One month on from my last posting, now August 9th 2020. Johin is doing very well IMO. Now completely green, but I am hoping for some good Autumn colours.

    Well it's the last day of August 2020 and as we have had a lot of rain and cooler weather here in England over the past two weeks, all my maples are doing well for the time of year.
    The greens have become more intense on my Johin. If you love the emerald greens that I do in Summer, then this is one for you.
    It does have those lovely bronzes in the Spring also.

    10th September 2020 and my maples are now racing into Autumnal colours. So warm and sunny at the moment, it does seem a bit strange though.
    Now my Johin is one of my Shirasawanum's that has held it's Summer colour really well, as can be seen in my photo. So a definate Autumn show is expected this year.

    20th September 2020 and new growth plus some strange colouring on my maples now. But my Johin is holding it's greens still. One of only a few in my garden that is.

    24th September 2020 and Autumn has really hit home quickly. Cold nights and lots of rain already. But raindrops on colourful leaves is why Autumn is a favorite for so many of us Maple enthusiasts.
    Johin is just starting to turn now.

    11th October 2020 and I thought I would show my Johin as it is just turning with the yellows at the edges of the lobes. I think this is a pretty phase for this tree and arguably better than it's full Autumn colour.

    Hello @Acerholic . . . it's hard not to be inspired by the numbers and variety of Acers you grow. If I'm not being presumptuous to ask, how large is your garden? I have quite a bit of space here but the growing conditions are not good for most anything, including maples. (Shallow, rocky soil; too much sun, watering challenges.) Still, I'm curious to find out how many I might aspire to acquire. :-)

    @Margot Good morning Margot, I don't have a big garden at all, I just arrange and prune to get the required sizes. It is surprising how many you can get in a small area. At last weeks Maple Society AGM a prominent member from the US said how he has 1200 maples in 2 acres.
    I have 160 maples in a 5th of an acre.
    That is the beauty of Japanese maples, you can have more than you think you can.
    My friend has over 400 cultivars in a smaller space than me, then there are others who keep them in pots and have massive collections.
    Shade is the most important thing to consider but this can be achieved by planting a larger non maple to give some shelter. There are some including Atropurpureum that do very nicely indeed in full sun and give wonderful colour from Spring to Autumn.

    So if you want to grow a few, I say go for it. But perhaps consider large decorative pots.
    Thanks for your nice comments and good night. My shift now Lol.

    Thank you @Acerholic. Your comments give me much food for thought - and inspiration! I agree that planting in pots is the way to go, not only for maples but also for other challenging plants so that I can be sure they get enough water.

    Yes - your shift now . . . I often look at the time when sending or receiving and calculate what time it is in Hampshire. Good night!

    24th October 2020 and my Johin is only just starting to turn. Very late this year. But thought I would share it to show that you can never guarantee anything in the maple world.

    31st October 2020 and my Johin is about to drop, so before they do here is how it looks today. The yellows are pretty to the end and add some needed brightness to my garden.
