A florist’s window in Poland, the board behind it advertising seasonal work and funeral arrangements. There is plenty in the frame: anthuriums, garden roses, peonies, chrysanthemums, tulips at the bottom, statice off to the right. None of it registers. The cream Phalaenopsis spray comes forward and turns everything else into background. Growers know the effect without needing it explained. It is worth pulling apart anyway, because the reasons are structural rather than aesthetic, and because they explain the odd shape of the trade that has grown up around this genus.
