Red Flowered Cactus

This cactus put on a show today with several red flowers.

I wonder why it is so difficult to take pictures of very red things?

Last year, this plant was infested with tiny, white mealy bugs. I noticed the bugs before, but they usually come and go on their own. Several months ago, though, I took the time to manually remove them with a pair of tweezers. I guess my work paid off as this seems to have resulted in more blooms this time.

This other pot of the same cactus was growing, neglected, underneath the shade of some bushes. The plant seems to have grown longer in its search for more sunlight. And, the flower blooms are going to happen much later than the other plant.
