Homeowner Growing & Maintenance Tips:

Platycodons are easy, trouble-free perennials that thrive in almost any soil as long as it is well-drained. They can easily adapt to grow in either full sun or part shade. Be patient in the spring, as this genus is slow to emerge. Cut the whole plant back after the first hard frost.
