This award-winning British ball dahlia is an absolute masterpiece of living architecture!

Every single petal is folded into flawless, overlapping symmetry on rock-solid, laser-straight stems

GROOVY TIP: Bright yellow ball dahlias like 'Polventon Supreme' act as natural "color boosters" in garden design!
