Sidehill Trishie dahlia bloom with buttercream yellow petals and soft peach-pink undertones

Sidehill Trishie Dahlia

Sidehill Trishie is a warm, softly colored formal decorative dahlia, with buttercream-yellow petals washed in peach and pink. The color is especially beautiful toward the center of the bloom, where the warmer yellow tones give the flower a gentle glow.

The 4–6 inch blooms have a full, rounded form and a soft palette that works beautifully with peach, blush, cream, and warmer late-summer colors. Its upward-facing flowers also make Sidehill Trishie particularly useful for cutting and floral design.

Why We Grow It: Sidehill Trishie is the most romantic yellow we’ve grown. Its warm buttercream color is softened with peach and pink, giving it a gentleness that most yellows don’t have. It has all the glow of a yellow dahlia, but with a softer, more romantic character that makes it especially easy to use in floral work.
