SHAMROCK is a flower and plant business based in Dobashi-cho, Naka Ward, Hiroshima. Guided by the belief that plants express vitality, beauty, tenderness and character, the team creates floral designs that help people mark meaningful moments and enhance everyday spaces.

Bouquets are available in round, long and natural styles, while arrangements can be made in complementary forms and color palettes to suit the recipient or occasion. Customers may request flowers sourced to their preferences with advance notice. SHAMROCK also makes dried-flower products using flowers it selects and prepares, including bouquets, wreaths, swags and decorative pieces.
