This is a pencil cactus. But really, it is a succulent. The stems are round like a dowel. During cooler months, they glow in vivid shades of pink, orange, and yellow. How fun is that? Their nickname is “Sticks On Fire”.

Even I’m amazed by My achievement
but I confess that there were disappointments.
Cacti, for example. I never really got them right.
Can’t imagine what I meant them to look like,
but certainly, they turned out wrong.
Maybe I had the plans upside down.
