cactus flowers are so lovely
15 years with you is some time - seems you are taking care of cactus very good
May cactus story : I remember when I was kid I bought the cactus and it had nice pink flower. Later however , as I recall , I found out that flower was fake. I was disappointed at the time. I think after that I got some cacti but they where without flowers.
Good to check flowers of cactus when you want to buy one.
I love these little flowers too, when I saw them first time I was surprised with such intense colour. Yes, it is important to make sure what kind of flower we want to buy :)
