Early in the morning I saw that one of the cacti on my window sill had started to grow a long appendage carrying a flower bud. By about 8 p.m. the bud started opening up.
Around midnight the flower was in full bloom with delicate pink petals spread wide to allow some desert insect to spread pollen and repeat the circle of life. Sadly, that would not happen on my window sil. 🙁
By the next morning the flower had wilted away again.
