Keeping Mill Valley in bloom since 1985

Bloomathon 1

Bloomathon is a dedicated group of volunteers who are focused on the beautification of Mill Valley. Founding members planted their first Daffodil bulbs in the Miller Avenue medians in 1985 and since, the group has planted thousands of bulbs, shrubs, trees, annuals and natives throughout the city in public spaces and parks.

Bloomathon’s work contributes greatly to creating the pleasant and charming atmosphere that is Mill Valley. Their plantings are only made possible by community donations and volunteer hands. The group is always looking for new participants. Please join us at one of regular meetings or an upcoming event. Click here to view our Citywide event calendar
