| | Fall Blooming Bulbs (Site not responding. Last check: ) |
 | | In zones 6 or higher, spring- and summer-blooming herbaceous perennials are usually divided after bloom, either in late summer or in early fall as the foliage dies down. |
 | | Fall-blooming herbaceous perennials are usually divided in spring when the foliage is 2 to 3 inches tall, giving the plants an entire growing season to recover. |
 | | Some herbaceous perennials such as beebalm and chrysanthemum benefit from being divided every year, while other herbaceous perennials such as gas plant, false lupine, lavender, lenten rose, monkshood, oriental poppy, sea holly, and spurges are best left undisturbed as long as possible, or never divided at all. |
