Feel free to use the calculator for your own reference, but it's not perfect! Stay tuned for a Michigan-specific version.)
  • Plant species recommendations. This is a list of plants we commonly use in rain gardens, with details about flower color, height, and preferences for wetness and sunlight. We grow most of these plants at Calvin and several will be available at the plant sale on May 5 at the Bunker Interpretive Center.
