I have a feeling that Home Depot and Lowe's (we only have a Lowe's) purchase orchids depending on their climate and perceived belief on what will sell. Our Lowe's never has much to choose from, generally they will all be Phal. Sometimes there will be bare-rooted plants in mesh bags that are for sell. Those are usually Cattleya Alliance plants and often they will just be called "Cattleya", without proper labeling. I often see people post that that bought a (regularly-priced at $24.95) Phal./other orchid for $5.00. I never see our store discount plants like that. When I go to Lowe's I always check though!
