Phalaenopsis Flower Upside Down: Phototropic Peduncle and Light Position

Question:

Hybrid Phal bought month ago. One recent flower bloomed awkward—upside down (dorsal sepal bottom, labellum top facing down). 1–2 buds remain. Common?

Answer:

David, could be aberration or growing method. Peduncle (flower connector) is highly phototropic (light-responsive). If plant position relative to light changes while bud develops, flower twists out of normal position. General rule: Keep emerging spike position fixed relative to light until flowers open.
