Hi, Could someone please identify the Cactus in the attached photos? It blooms throughout the summer months, profusely this year. The fruits mature to a red/purple color. I am not sure if they're edible. I have searched a lot of the Night Blooming Cactus photos but don't see a good match. Assuming I have the correct plant name I am looking for the exact variety of such. The blooms have no fragrance and close up during the day. They're usually fully open in a morning and ALL blooms face in a western direction. Thank you so much in advance. Andrew Close.
