My Argentine Giant cactus has several buds on it that will likely open into giant white flowers. It will probably be a couple of days, but three of the five buds are almost ready to pop open with the beautiful flowers. The other two flower buds will follow with a couple more flowers a bit later.
The cactus isn’t particularly a giant, but the six-to-eight inch diameter flowers certainly are, among common cactus flowers. The cactus itself is only about fifteen inches tall, hardly a giant when compared to the saguaro, for instance.
The flowers smell like a fresh sea breeze the evening they open. I will post pictures of the flowers when they open. Click on the image to enlarge.
