Semi-Cactus · 4–6"Red1954

Prince Noir was first introduced in 1954. Wine-dark ruffled petals open on long wands that lean into late summer light. A postwar heirloom rescued from a British national collection, it survived decades of obscurity on the strength of its color alone. Prince Noir is a semi-cactus dahlia that opens 4–6" blooms in red.

Growing Prince Noir

Stake early and deep because the canes push past shoulder height in good soil. Pinch at the first fork of true leaves to force branching from the base. Watch for late-season wind, which can snap the long flowering stems at the joint. Disbud lightly if you want fewer but cleaner ruffled blooms.

Spacing: Space roughly 2–3 ft apart
Staking: Stake early — stems carry heavy blooms and lean in wind
