SLOW FLOWERS SUMMIT ANNOUNCES 10TH ANNIVERSARY CONFERENCE
Slow Flowers Society’s annual gathering returns to FILOLI HISTORIC HOUSE AND GARDEN for a collective focus on floral design, flower farming, and sustainability education, June 20-22, 2027
SEATTLE, WA (September 22, 2026) -- Debra Prinzing, founder and creative director of Slow Flowers LLC, announced the speaker lineup for the 2027 Slow Flowers Summit, taking place live and in-person on the grounds of the famed cultural destination, Filoli Historic House and Garden, located in the San Francisco Bay Area .
“We’re thrilled to again partner with the horticulture and floriculture teams at Filoli Historic House and Garden, the location of our unforgettable 2021 Slow Flowers Summit,” Prinzing said. “Filoli plays a leading role in horticulture and gardening education, with an emphasis on sustainability and design – and we know our attendees will be enriched by their time there.”
Following two years of successful online programming as the Slow Flowers Worldwide Summit (2025 and 2026), the Summit returns to a popular live, in-person format. “We’re celebrating our 10th annual conference for the Slow Flowers community, as we highlight new ideas and leading voices in floral design, flower farming, and sustainability topics,” she added.
The Slow Flowers Summit will take place June 20-22, 2027 during which attendees will experience a full immersion of the gardens, landscape, and natural areas at Filoli. “Our guests will learn from expert Slow Flowers instructors, including from Filoli’s horticulture and floriculture teams. We’re planning a number of special, hands-on experiences during which they will learn from and engage with floral and botanical experts,” Prinzing noted. “A highlight of the 2-1/2-day conference will be the ‘Floral Takeover’ of Filoli’s historic mansion as teams of designers embellish and adorn interior rooms and exterior spaces for a unique display of locally-grown botanicals.”

The Slow Flowers Summit theme for 2027 is “California Blooms,” with speaker invitations extended to California-based designers, flower farmers, and experts from the Slow Flowers membership. The conference will be headlined by Oakland-based landscape designer Leslie Bennett, owner and principal designer of Pine House Edible Gardens. Bennett is the author of Garden Wonderland and the creator of the Black Sanctuary Gardens project.
