    A lot of fun and taught well
  • Playful Winter Collage - Botanical Art Workshop

    Mary K. • March 12, 2025
    I loved the class and it met my expectations. I do collage at home on my own but it was nice to get new ideas and to servers others were doing.
  • Botanical Print-Making Workshop

    Anonymous • May 11, 2023
    Perfect class. Offered just the right amount of instruction and information in order to play around with the concepts and walk away with the ability to do more on your own. The space was airy and spacious. Also appreciated that materials were included. Thank you!

    Good information, great presentation. Thanks, Bess.
  • Rose Pruning

    Anonymous • February 13, 2021
    Lots of practical information for the beginning gardener, or anyone who has grown roses but never was sure about what to prune and when. All of my questions were answered during the class. The instructor was highly qualified and had a good sense of humor.
  • Japanese Garden Pruning

    Anonymous • February 21, 2020
    The one issue was that the organization did not have me on the list when I checked. The registration was done on CourseHorse 2 weeks in advance.
  • Gardening with the Seasons: Winter

    Anonymous • January 24, 2019
    concise and clear explanation of winter tasks such as pruning (and which pruning for summer) including how to reduce waterspouts, common weeds that are best tackled in winter, kinds of mulches and useage, etc.

    Anca I. • October 10, 2018
    Superb easy to go along teaching! Never did that before & she’s a great teacher. Location is not so easy to go to due to crazy traffic, but it was worth it
  • Native Plants 101: Edible Native Plants

    Anonymous • August 9, 2018
    The handouts were tough to read and while the two teachers did a good job and knew the material, it would’ve been better to not look at the Yesler Swamp for IDing. I thought I was going to get a better idea of what plants should go in a yard/garden.
