Yellow Moon Flowers Oenothera acaulis aurea

Common Names in English:

Dandelion-Leaved Sundrop, Evening Primrose, Oenothera acaulis aurea

My friend Colleen gave me some of these and my first one bloomed tonight. I am so excited!


Charming yellow flowers are striking against the rich green lanceolate leaves. Flowers appear in early summer and are fragrant. Four winged seed pods are produced after the flowers and are quite attractive


These flowers bloom in the evening between 8:30 and 9:30 pm from May through August I am told. Blossoms will come out after dark and be spent by noon the following day. Each plant will produce several blossoms each week throughout the four months. Another favorite name for them is yellow moonflower for obvious reasons. Mine were transplanted to my garden from some flower boxes that my friend Colleen planted them in. They had bloomed so we were not sure how they would take the shock of being transplanted into my rock garden but one bloomed in a exactly a week after being transplanted.
