This is a photo of leaf color comparison. The bottom orchid is a Phal violacea and the 2 above are Phal hybrids ..
My Phal hybrids have species in their lineage but are further removed than my Phal. violacea cross.
Your Phal 'Sweet Memory' has Phal violacea as one of it's parents.
Many phal species leaves are 'granny apple' green in color.
The same green color is apparent on a leaf that is growing and is most apparent closest to the crown ( or where the leaves meet in the center)
No worries
