~ Eileen Mullen, The Lion Head Beach Association
[Edwina’s] presentation was inspirational, entertaining & filled with a joyous sense of freedom – all while imparting such important information & a new way of looking at landscapes & plantings. I am so interested in getting as many of our residents as possible to understand a new perception of beauty.
~ Jean Thatcher, Three Harbors Garden Club
We received wonderful, positive feedback from so many of the attendees who said that they felt informed and empowered to make changes in their home landscape practice towards a more ‘magical’ and sustainable model.
~Lisa de Guzman, Three Harbors Garden Club
My husband and I are totally inspired! And the feedback today says…so are the 175 + guests listening last night.
