Hollyhill Diamond

Hollyhill Diamond is a bright, clean white semi-cactus dahlia with strong form and excellent presence. The blooms fall into the BB size range, typically measuring just over 4 inches up to 6 inches, with pointed, narrow petals that give the flower structure, movement, and a crisp finish. Plants grow to approximately 4 feet in height and hold their blooms well on sturdy stems.

This variety is especially valued for its clarity of colour and architectural form. The true white petals make Hollyhill Diamond highly versatile, equally effective in classic white-and-green arrangements, modern designs, or as contrast alongside bold colours. In the garden, it is very showy and dependable, while in arrangements it adds texture and light without heaviness.
