Mark Weathington - Author, Director of JC Raulston Arboretum, Horticulture Professor

Silas Zoeller - Far Reaches Botanical Conservancy Horticulturist, Rare Plant Enthusiast

Botanic gardens can feel as though they’ve always been there, shaped over generations and rooted in long-established institutions. But what does it take to create one now?

Join Cultivating Place host Jennifer Jewell for a conversation with three plantsmen experiencing that process firsthand. Sean Hogan is developing a new botanic garden in Portland, Silas Zoeller is helping guide Far Reaches Farm’s evolution into a botanic garden, and Mark Weathington brings the perspective of the JC Raulston Arboretum as Juniper Level Botanic Garden becomes part of its future.

Together, they’ll consider what transforms a remarkable collection of plants into a botanic garden, what these institutions can offer their communities, and how decisions being made today may shape the plants, knowledge, and landscapes preserved for generations to come.

The Four-Season Grass Garden

Susan Calhoun - Fine Gardening Contributing Editor Landscape Designer

Blooms & Bubbles - Botanical Love Letters: A Secret Message for the Table

Teresa Rao - Belle Pétale Founder, Floral Designer

Additional Ticket Required

View More
Flowers have always had something to say. Teresa Rao, founder of Belle Pétale, brings the romance and symbolism of the Victorian language of flowers to the design table, where you’ll create a seasonal centerpiece with a message all its own.

Teresa will introduce you to the hidden meanings associated with flowers, herbs, and foliage, then help you choose and combine botanicals that express a sentiment personal to you. As your arrangement takes shape, you’ll discover how meaning can add another layer to floral design, turning a beautiful collection of flowers into something far more personal.

You’ll leave with your own Language of Flowers centerpiece, along with inspiration for creating arrangements that are as articulate as they are beautiful.
