dang it, i wrote a good amount to explain this but i pressed backspace by accident and its all gone
anyways, looking at the pots i think the first 3 are from matsui. the paph has culture similar to phalaenopsis. the next 2 are oncidiums both will fit to the intergeneric culture. and phals well theyre phals and will grow almost anywhere. read up on them since they have very beasic culture.
the blue one i might say is slightly different because of the species used to get "blue" but idk, i would researcg it. its lovely btw and im kinda envious as i want a blue phal. whered you get this one at again?
