Our Mammoth Sunflowers are bold, field-grown statement blooms harvested at peak stage for maximum impact and vase life. These towering stems are ideal for large-scale installations, ceremony pieces, statement arrangements, and late-summer displays.

Grown locally and cut fresh, each bloom carries natural variation and strong stems that hold up beautifully in design work. Because of their impressive head size and height, Mammoths are best suited for floor arrangements, event work, and designs where scale matters.

Primary Harvest: July–September
Cut when outer petals have fully opened but center disk is still tight for best longevity.
