I used to have these in my other garden, given to me by a sweet Japanese friend from her garden. They were such easy to grow plants, not fussy at all despite their delicate orchid looks. She later passed away and it was a special memento of her but one year they didn't return.
Nice shot Marylyn!
Unfortunately these little beauties were at an arboretum and not in my garden. I would love to have them!!
