Night blooming yellow wildflower
Does anyone know of a wildflower that blooms at night. I no longer have it, but I would sure love to know the name or get some seeds. It grows about 3 to 4 feet high and late evening you can actually watch the flowers open before your eyes. It is so fun for children to see. It has pure yellow blooms which go away when the morning sun comes up. Hope someone knows of this plant so they can help me find it.
Thank you so much
