Dahlia 'Cactus' Hybrids are spectacular ornamental dahlias known for their large, fully double flowers with long, narrow, pointed petals that curve outward, creating a dramatic "cactus-like" appearance. They bloom in a wide range of colors including red, yellow, orange, pink, purple, white, and bicolors. They are excellent for flower beds, borders, containers, landscaping, and cut flower gardens.
