Bachelor's button

Bachelor's button is a sweet little flower, reseeding freely here and there in your garden, adding a bright touch of true, clear blue wherever it chooses to sprout. This easy-growing annual produces papery flowers atop tall stems; the blooms are great for cutting and drying.

The plant is happiest in sandy loam. It doesn't need much, if any fertilizer, and tolerates drought, but prefers moderate moisture. Plant from seed directly in the garden after the last frost in your region. Space to 6 to 12 inches apart. Deadhead after the first flush of bloom to encourage a second flush. But if you want lots of reseeding next year, allow some flowers at some point to ripen on the plant and go to seed.
