I never give them nicknames but i do give them clonal names if i know the plant is original and seed grown.
I mostly name them after friends and certain characteristics of the blooms.
I do like your nickname "Nicki Minaj" for that Dendrobium. Maybe i'll give a name like that to one of my Phrag kovachiis
My daughter names all her plants.... I am with Ray....the orchids are sweet babies and pretty girls when in bloom or putting out new roots and @#%&$%&&%!!@ when they are not growing good roots, stalled or haven't bloomed in over a year... I recently threatened a Dendrochilium that sat there for 8 months and after the stern talking I had with it, including the verbiage that I was going to throw it away, It promptly put out three inflorescences....
I don't generally give my orchids nicknames like this, but if one is under-performing I sometimes start referring to it as "Mulch" or "Compost" to see if it gets the hint...
Your dendrobium is Comet King 'Akatsuki'.
I have one in bloom also. How do you like the scent?
I love mine.
By the way, I only give nicknames to NOIDs since I want to call them or remember them by something other than just NOID #1, NOID #2....
but mines are normally much more boring than yours. hahaha
Hadn't thought much about it, but I suppose certain descriptions do come to mind with certain orchids. I'll post some later with pics, but for now, enjoy the term "Spider-Phal".
I grow Neofinetia falcata. Every plant I own has a Japanese name. The Japanese are far more memorable than what I can devise. Here is my Neofinetia falcata "Yoroidishi"
