The green, facile, low‐cost and sustainable fabrication of a SERS substrate is reported, through physical vapor deposition of silver on rose petals. The hierarchical structures on the petal contribute to not only the superhydrophobicity, but also E‐field enhancements. Therefore, the rose‐petal‐based SERS substrate shows high efficiency in the detection of R6G, and a detection limit of 10 ‐9 M is achieved.
