Looking for a taller perennial statement in your garden? Do you want a great cut flower? Try the Tall Cosmos, an erect annual with wispy foliage and flowers that are 2 to 3" across. Blooms come in shades of rose-pink to lilac, but cultivars in whites and bi-colors may also be found. Most are suited to the back of the garden bed, using other plants around them to lend a little support. Flowers continuously from spring to fall.
