    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.

    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.
