Continuous Perennial Color

Planning your garden so there is color from spring through fall

Perennials are wonderful garden plants that will greet you each season with a happy bloom.  The trick is to have something in bloom constantly.

  1. Know in which months each perennial blooms
  2. Choose plants that bloom for at least 8 weeks for your “core” group of perennials.
  3. Fill in with other plants that support the long-bloomers.

Use the following information to help you plan for continuous color in your perennial garden.
