FAQs About Annual Summer Flowers
What is the Difference Between Annuals and Perennials?
Knowing the difference between annual and perennial flowers will help you decide which type works better for your gardening needs. Annuals are plants that grow for just one season and that’s it. To get more of that plant, you will need to replant it each year.
Perennials will save you that extra trip to the home improvement store/nursery. This is because perennials will grow back for several years before replanting is required.
While this may make it seem like perennials are the obvious choice, there are benefits of annuals worth considering. One major upside of annuals is the extended blooming season. If you take excellent care of your annuals, you can prolong their life into the fall season.
For the best results, try planting both to find out which flowers are worth your time. There are so many to try out and it can be a very fun gardening experiment.
What is my Hardiness Zone?
For annual flowers that bloom all summer, it is best to find out what grows in your area. To find out what hardiness zone you live in, check out the USDA Plant Hardiness Zone Map. This will give you an idea of what will easily grow and what will take more effort.
