Times of flowering are estimates based on references and
my own observations. They can vary depending on elevation and climate.
Great effort has been made to correctly identify wildflower species. If you believe a species has been misidentified,
please send an email
and I will make corrections. This feedback will strengthen the site

Thank you to Sara, Kate and Charlie for their patience
during family hikes and for allowing me to dominate our computer for
several months. Thank you also to my friends and colleagues who have
assisted with plant identification. And to my parents, whose copy of
Eliot Porter's Birds of North America was an inspiration.
