River Merle dahlia collection

Discover the River Merle (RM) Dahlia Collection from Hailey Sly of River Merle Farm  — a collection of distinctive, collector-quality dahlias known for their extraordinary color expression, artistic patterns, strong garden performance, and exceptional bouquet presence.

At Pedaling Petals, we believe every remarkable dahlia begins with the person who creates it. We are proud to be a licensed seller of River Merle dahlias, offering authentic introductions while supporting Hailey’s ongoing hybridizing program. A portion of every RM dahlia sale goes directly back to River Merle to help fund the next generation of unique and beautiful introductions.

River Merle varieties are selected for the qualities that make gardeners and floral designers stop and take notice: rich, painterly colors, intriguing petal patterns, strong stems, and blooms that bring depth and personality to the garden and vase.

Our RM collection is grown and evaluated here at Pedaling Petals, where we experience each variety firsthand — watching how the colors develop, how the plants perform, and which blooms become unforgettable moments in the garden.

For collectors, designers, and gardeners looking for dahlias that feel truly special, River Merle offers a rare combination of artistry and performance.
