When to plant purple fountain grass

Purple fountain grass is a tender mounding grass that NC State notes is normally grown as an annual (it is hardy only in zones 9-11). Set out nursery plants in spring after the danger of frost has passed; it blooms from summer until frost. Note it self-seeds readily and is considered invasive in some southwestern coastal states.

Purple Fountain Grass is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
