Bigleaf Hydrangea 'Hopcorn': Unique Popcorn-Textured Mophead

Bigleaf Hydrangea 'Hopcorn': Popcorn Texture Meets Hydrangea

Hydrangea macrophylla 'Hopcorn' (PP18391, also known as Hovaria® Hopcorn) is a startlingly original cultivar whose sterile florets are so deeply cupped and inflated that they resemble popped corn kernels—hence the playful name. Hybridized by Hofstede and introduced in 2006, it adds a whimsical, tactile dimension to the mophead class.

Popcorn Florets

Each sterile floret is dramatically involute (cupped inward), forming a tight, balloon-like pouch. The mophead inflorescence is a mass of these 3D "kernels," creating a bubbly, tactile surface that begs to be touched. Colors range from soft pink to lavender-blue (pH dependent). The florets are thick and waxy, holding their inflated shape for weeks. The overall effect is whimsical and utterly unique.

The plant is compact, 2–3 feet tall and wide, with sturdy stems and glossy green foliage.

Dutch Innovation

Bred by Hofstede (Netherlands) as part of the Hovaria® program, which focuses on novel flower forms and textures. 'Hopcorn' pushes the boundaries of hydrangea morphology. Standard culture: morning shade, moist soil, zones 6–9. Blooms on old wood. The cupped florets can hold rainwater, so a sheltered site helps preserve the display.
