There is no rush yet. Some cool season bedding plants can go into their gardens as late as autumn. Ornamental kale and cyclamen can be as late as winter if necessary. Locally, autumn and winter can be a bit later than elsewhere. Also, different cool season bedding plants rely on different schedules. Ornamental kale and cyclamen actually prefer to wait.

Cool season bedding plants are the same as winter bedding plants. They also qualify as cool season annuals and winter annuals. However, most have potential to be perennial, and some can perform after winter. Some are warm season bedding plants within cooler climates. Locally warm summers and mild winters limit their performance very differently.

All bedding plants provide a profusion of temporary floral color for their assigned season. Cool season bedding plants replace deteriorating warm season bedding plants. Within a few months, warm season bedding plants will become seasonal again. Most that can be perennials are disposable for simplicity. Replacement is generally simpler than salvage.

Installation of bedding plants is often contingent on performance of their predecessors. If petunias of last summer still bloom nicely, pansies for autumn may need to wait. Pansies might need to be early though, if petunias are already shabby. Most cool season bedding plants are fortunately adaptable in that regard. Merely a few must wait for cooler weather.

Scheduling for seeding of cool season bedding plants is not as adaptable. Seed can not germinate and grow faster if late. Actually, seedlings grow slower as weather gets cooler. Seedlings for some species should be growing already. Others should start about now or rather soon. Some should start in cell packs or flats. Several others prefer direct sowing.

Pansy and viola are probably the most familiar and reliable cool season bedding plants. Marigold and perhaps snapdragon are popular now, but may not perform through winter. They become seasonal again as winter ends. Sweet William and a few sorts of primrose are potentially perennial. Any that survive through summer could resume blooming soon.
