Caladium Fancy Leaf 'Postman Joyner (Ships in Spring)
Caladium
Caladium 'Postman Joyner' is a fancy‑leaf tuberous perennial prized for its vivid red leaves accented by bold green margins and delicate veining. It thrives in partial to full shade and prefers humus‑rich, moist, well‑drained soil. Its striking foliage brings strong color to shaded borders, containers, and indoor plantings. Though small calla‑type blooms may appear in summer, it is primarily grown for its decorative leaves. In colder climates, tubers should be lifted and stored indoors before winter to ensure a fresh display the following season.
