Anthurium "Pustules" Explained: Normal Seed Development

Reader Concern: Yellow Bumps on Anthurium Flower Spike

Josie noticed green, then yellow, tomato-like globules on the spadix (spike) of her anthurium flower. She watered and fertilized regularly, provided bright indirect light (northwest exposure), and wondered if this signaled a problem.

Expert Explanation: Botany Lesson

Will Creed clarified the anatomy: the colorful "flower" is actually a spathe (modified leaf), while the spike is the spadix bearing tiny true flowers. The yellow globules are developing seeds—a sign of successful pollination. Since most cultivated anthuriums are hybrids, the seeds are likely sterile.

Verdict: Plant Is Healthy

No action needed. The anthurium is thriving. Simply remove the flower stem when it fades. Continue current care routine.
