Bloom Season of Perennials

Posted on

This table shows the relative time of blooming of perennials. Because actual bloom time and length of bloom vary from place to place and even year to year, it is only a rough estimate, to be used for an initial trial. If local tables of bloom time are available, use them to refine this one. By keeping notes of bloom time in your garden, you can make a personal bloom time table that will be more accurate than any published table.
