    I just added this tree to my garden. I placed it in full sun which may or may not be the best for the tree. Of all the red/pink upright type trees this is the one i have seen the most amount of varigation. it is a very nice tree with mostly dark rich red leaves. On some branches you will get the varigation but not all. It is well worth having in the garden.

    As the tree sits in my yard it looks better and better and is becoming one of my favorites. The pink coloration is coming out more and more. It also has wonderful pinl striping on the bark. I have the tree planted in full sun then again we have not seen the sun this year. If the coloration keeps on this path, I will have a new tree in my top ten list.

    I know you've only had the tree a short time, but how would you compare it to Taimin nishiki? Any quirks or sensitivities you've noticed? Curious how well it would stand up to the intense Kansas heat...

    I have had two Taimin nishiki for two years and have seen no varigation. As for Rainbow, it has loads of varigation and the varigation has increased since i have put it in the ground.

    Just got one yesterday after waiting over a year to find one in the U.K.
    I heard it likes afternoon sun?
    To keep the variegation you need to prune non-variegated branches?

    I can't give you a definite opinion about exposure, but so far I've found that the variegated specimens I have tend to fare better in semi-shade: sun in the morning and in the evening, but shade during the hottest hours of the day. But perhaps we have more hot sunny days here than in Britain. My son who is now in Belfast told me they've had a heat wave a few days ago... 23°C! Here it was about 30°
    ;°)

    I usually prune non-variegated branches because they tend to be stronger and after a while they can take over the variegated branches. This is obvious on variegated Acer negundo planted in a neaby street: half of them have reverted to plain green and on others, half the branches are taking the same path. But I've read different opinions...

    Anyway, mine is developping well, the new shoots are a vibrant red (I had to enhance the photos a bit to get closer to the real colour):

    Thank you, we have had close to 30 degrees too, hasn't rained for nearly three weeks. I have had to put alot of my trees in shade but my large katsura is in full sun all day doing great. My rainbow got a little crisp on the tips on 1 or 2 leaves but on the whole is ok. The new growth on yours looks amazing. I find adding contrast slighty achieves a more realistic representation.
