There are a lot of different species told apart by fine botanical characteristics - except for a comparatively small number that don't look like any others.

Thanks for the info, those look like the ones. Another question for anyone who cares to offer your thoughts; those trees in the last pictures - what should I do about those. It seems that 2 of those cherry trees have sprouted up between 3 older dogwoods. The dogwoods are in decent shape, although they all have some 'dead' section up higher. I can't imagine all 5 of those trees being able to co-exist in that space. It appears that the prior owners cut the cherry down to the ground (those 2 trees have sprouted up out of an old trunk in the ground). Any ideas?

Thanks Ron! I believe you are right. Growing on the same support is a plant with blooms that look like Akatsuki no Murasaki and they were all planted from the same packet of seeds. The blue is a bit darker and more saturated than in this picture. They came from a trade packet labeled Hatsu Arashi, which none of the blooms resemble. I think it is a matter of a mislabeled packet compounded by the variation you mention. I am confident you have solved my mystery! Alana
