This Birdcage Evening Primrose with large white flowers can be seen in the sands of Anza-Borrego Desert State Park, California. Flowers open in the evening. Oenothera californica (California evening primrose) is very similar to oenothera deltoides but with smaller leaves - often mostly hidden by the large petals; the deltoides species has leaves that are twice as long, projecting out beneath the flower head. It takes me a while to research them. Hopefully I identify the plants in my pictures correctly. The plant is grayish with basal, deltoid leaves. The large white flowers turn pinkish as they mature. When the plants die, the stems curl upward and form the "birdcage" for which the common name is derived.
這個有白色大花的鳥籠月見草(Birdcage Evening Primrose)在加州的 Anza-Borrego 沙漠州立公園的沙地上可看到它。花在傍晚開放。Oenothera californica（加利福尼亞月見草）與 oenothera deltoides 非常相似，但葉子較小 - 通常大部分隱藏在大花瓣中而deltoides 物種的葉子有兩倍長，從花頭下方伸出。我花了一些時間來研究它們。 希望我能正確識別照片中的植物。它是灰色，基生葉呈三角形。白色的大花在成熟時會變成粉紅色。當植物死時，莖向上捲曲形成“鳥籠”狀，俗名由此而來。
