Just forty plants?
I found with collecting orchids, it is best to decide what qualities in an orchid are important to you and go from there. I have limited space for the orchids so I now only collect smaller orchids with some being miniatures. I prefer fragrant orchids but I do have three or four that are not fragrant because I like the flowers.
I have a few CP's but they were bought to solve some issue...Sundew for the fruit flies, Butterwort for the fungus gnats, Nepenthes for the flies/yellow jackets, Purple pitcher plant...vendor sent it by mistake...Venus fly trap...flies. None of the ones I have are complicated to grow, thankfully. I can see how Nepenthes could be very addicting but, fortunately, the other plants limit how many CP's and orchids I can grow.
Good luck with the orchids and have fun!
