I should know better than to start proclaiming "favorite" cactus blooms, as I did when my night blooming cactus bloomed last week. Right after that bloom died, one of my newest cacti, labeled just "Trichocereus" bloomed and what a gorgeous bloom it was! This one truly is in line for my favorite day bloomer anyway! The bloom lasted two full days, on my patio, out of direct sunlight. This cactus is new to my collection- bought within the last month from a local nursery. If anyone knows more about what kind of Trichocereus this might be please do comment. I had some fun doing some real close-up shots of the bloom- the red-pink-lavender colors were really striking.
