Cosmos bipinnatus (90-100 days) These shimmering delicate beauties were named for the pleating of cupcake papers, evoked by the intricately fused folding of the outer petals. But not described is how the lightweight blooms seem to float on upright stems, more like ballerinas pirouetting in tutus of white and pinks than like cupcake papers. Even better, some of the blooms are doubled, with extra petal tufts surrounding a central yellow button, making for a charming profusion of frills: a scene stealer in the garden. The 4' tall plants attract pollinators and have long stems for cutting. Deadhead to keep the blooms coming. Full sun. Especially attractive to pollinators.①
