What are biennial and perennial plants?
Definition. Annual plants complete their life cycle in one growing season. biennial plants are planted in one year, grow through the year, grow on and flower during the next year. Perennial plants grow strong year after year. Examples. Annual flowers grow for one long season, often into the fall, then die with the onset of freezing weather. Perennials come back year after year, with some plants that live just a couple years and others that continue growing for decades.Petunias are typically grown as annuals, meaning they complete their life cycle in one growing season and do not come back year after year. However, in some warmer climates, petunias may survive the winter and re-bloom the following spring, acting more like perennials.
Is marigold a perennial?
Most marigolds are annuals, which means they won’t come back the next year after they complete the first one. However, there are some perennial marigolds, such as the Mexican marigold (Tagetes lemmonii), that can come back year after year in suitable climates (typically USDA Zones 8-11). While most marigolds are annuals, some varieties are treated as perennial and can rebloom the following season because they self-seed. Pick according to your garden needs, and you’ll have a beautiful, new type of flower blooming this season in no time!When to Plant Marigolds. Young French and signet species can be planted from spring through midsummer, but the tall African marigolds are best planted right away in the spring (after the danger of frost has passed) because they are slower to mature and produce flowers.
What is the longest blooming perennial?
Which perennial flower has the longest bloom season? While many perennial flowers have long bloom times, the threadleaf coreopsis Moonbeam variety (Coreopsis verticillata ‘Moonbeam’) is a perennial with the longest bloom time. Moonbeam blooms early in the summer and will continue to do so until the end of the fall. Dahlias require full sun (at least 6 hours daily) to thrive and bloom abundantly. Southern growers might need to provide plants with afternoon shade if summer temperatures are extreme. Dahlias are cold sensitive and should not be planted until the soil has warmed to above 60°F (15°C) and all danger of frost has passed.Perennials have a longer lifespan than annuals and may bloom for several weeks or months each year. Lavender, jasmine, wisteria, peonies, and ornamental grasses are popular perennial choices for gardens, providing consistent beauty year after year.Botanically, dahlias are perennials, but their ability to return each year depends on how they’re cared for. In warm climates, they often come back with little effort.
Are roses a perennial or annual?
Roses are woody perennials, meaning their structure of stems and leaves doesn’t die back to the ground, and instead gets bigger each year. While some rose canes can be damaged by frost, in general, your rose shrub will remain through the winter and sprout new green growth each spring.

In pots you can plant as many bulbs together as you like, because the display will be less permanent, and you can replant the bulbs in the ground in one to two years’ time.When to Plant Daffodils.
