Thelocactus setispinus cactus is an eye-catcher to humans and insects alike. I mean who doesn’t give these flowers a second or third glance? Just look at it. It has a cheerful demeanor of a girl who just stepped out of a salon. Its flowers (7 cm wide) are silken glossy yellow with a red center the first day they bloom. The following day, they change their petal into a rosy color. And even if thelocactus doesn’t have flowers, it still looks interesting because its spine colors range from white and yellow through red all the way to brown.
