I have both in Zone 5b also. Neither are as green as pictures and Little Menehune didn't bloom this past year but I had accidently crushed it while working on my pond. I do have a very nice seedling out of Little Menehune and Bob Faulkners Psychedelicious that I crossed with 4 other mini's this past year. I wish I had a picture to post but I can't find one. Both seem to be slow growers with little bloom here but I will continue to use them when I can.
