I have a few unknown MG's in bloom. I don't know if they might just be variations of some of the known ones or different varieties. All but the last have bi-lobed foliage and the middle two are variegated.
Just some guesses for you
#3 could be Orhime, or Akatsuki no Hikari
#4 and #5 both look like seiryu
#6 could be viki harding
Thanks Fran. BTW 2 & 3 are the same plant as are 4 & 5. The blue blooms all have different amounts of stripes.
I don't know what #1 is but I sure like it a LOT!
