That kishu color is great, have you noticed any big differences between the two?
The foliage is quite different. I've written more on the topic
here and
here. Itoigawa fans out and is light green in color. Kishu balls up and is deeper, but bright green.
Itoigawa reverts to juvenile foliage more quickly with moderate pruning, and changes bronze color in the winter, as a response to cold.
Kishu seems to grow faster in my climate, by about double. The kishu region is a much warmer climate than the Itoigawa region, so that may have something to do with the differences between their growth rates in my area. They don't seem to go nearly as bronze in color.
Interestingly, the color change must be the results of some type of response cold-climate junipers have to cold weather. Here, ERC and RMJ go bronze in the winter, but Hollywood and San Jose don't.
Mites go after kishu more than Itoigawa in my yard. I have several of each in the ground together, and the kishu was attacked last year, and the itoigawas were a foot away and untouched.
The photo shows them just starting to go bronze...Itoigawa in the front, Kishu in the back, and in the can at the right. They were all planted as about 4" pots in Feb '12.
