For today's challenge, I submit a photo I took of my epiphyllum. The leaves are iridescent, so the flowers show up different shades of red and pink.
At first, since it's a cactus, I had it in direct sunlight but it didn't thrive at all. I then read up on it, saw that they grow in tropical forests, and in effect needs filtered light. Since I moved it into the shade underneath one of our trees, it has rewarded me with beautiful flowers year after year.

Enjoy your day and take care.
