Old House Dahlias

My name is Mark Harvey and I started Old House Dahlias in Portland, Oregon, more than eighteen years ago. Using my backyard as a starter plot. When I began planting dahlias, I had just four types. Today, I have more than 200 new and heirloom varieties of dahlias. I offer both tubers to enliven your garden and fresh cut flowers for special events or weddings . I ship tubers across the U.S and employ sustainable packaging.

Take a minute to check out my vibrant collection, which comprises stark contrasts in color and size and will add a unique distinctiveness to your garden. And feel free to call me with any questions you might have about starting or maintaining dahlias.

From August 23rd to frost 2025, I can be found Saturdays and Sundays at Old House Dahlias, now located in Tillamook, OR. You can also find Old House Dahlias’ cut flowers at Whole Foods Market Laurelhurst, Fremont, Hollywood, Tanasborne, Bridgeport, N.W. Couch St. Greenway as well as at Hawthorne New Seasons Concordia , 7 Corners ,QFC on Burnside, Sammy’s flowers  , Flowers By Donna  and Beaumont Floral.
