RM Riann is a burst of color and joy in the garden

At just 2.5 inches, the blooms may be small, but they have a warmth that makes them hard to overlook once you stop to look. The reddish-orange petals are warmed by a subtle wash of light apricot toward the outer petals, giving the formal decorative blooms a beautiful glow and a surprising amount of depth for such a petite flower.

RM Riann is one of those dahlias that doesn’t necessarily demand your attention from across the garden. Instead, you notice it as you walk by — and then wonder why you haven’t heard more about it.

Growing on a compact plant, RM Riann is a lovely choice for bouquets, cutting gardens, and gardeners who appreciate smaller blooms with plenty of personality. Its warm coloring also makes it an especially cheerful addition to late-summer and early-autumn arrangements.

Provenance

RM Riann is a River Merle dahlia from hybridizer Hailey Sly of River Merle Farm. Our RM Riann stock is grown from verified River Merle material as part of our commitment to preserving the provenance of the varieties we offer.

Pedaling Petals is a licensed seller of River Merle dahlias, and a portion of every sale supports Hailey’s ongoing hybridizing work.

At Pedaling Petals, provenance matters because every exceptional dahlia has a story that begins with the hybridizer who created it. We grow River Merle varieties in our own gardens so we can experience them firsthand — not simply sell a photograph and a description.
