You will hopefully learn some new tips about how to care for perennials, and fingers crossed, be convinced that perennials are the perfect plant choice for you. Let’s get started with a few basics.
What are perennial flowers?
Perennial flowers are flowers that you plant once, and they will grow back year after year. During the winter months, the plant will go dormant and protect itself, and in most cases, there is no need for you to dig it up or bring it indoors.
Over time, perennial flowers will continue to divide and grow, covering more garden space and growing in size.
Perennials are often confused with annuals because people often think that “annual” means the plant will GROW back annually. The best way to remember the difference is that annuals will need to be PLANTED annually, while perennials will not.
What does “perennial flowers” mean?
A plant must meet several qualifications in order to be considered perennial. For a plant to be considered a perennial plant, it must live for more than two years. It also typically blooms in the warmer spring and summer months, dies in the fall and winter months, then repeats the process in the spring.
During this time, the plant will maintain a rootstock under the soil that continues to live, even in the coldest of months. It simply remains dormant at this time.
If trying to classify which plants count as perennials, these qualifications are sure to help.
So what is the difference between annual and perennial flowers?
When planning your garden, it is important to know what the difference is between annual and perennial flowers. Knowing these differences can help you plan your garden accordingly and choose plants that will work well for you and your circumstances. Here are a few of the major differences between annual and perennial flowers:
Annuals bloom in the spring and summer months like most perennials, but they will die off during the cooler fall and winter months and not return. They might drop seeds while they bloom, which could possibly grow the following year, but this does NOT qualify them as a perennial.
Perennials will also bloom in the spring and summer months, and they will die in the cooler like fall and winter. They will grow again the following season, however not simply because they shed seeds. The reason perennials will regrow is due to their rootstock, which remains intact and alive during the cold months.
What are the benefits of planting perennials?
Now that you know the difference between annuals and perennials, you might be wondering about the benefits of planting perennials. Perennials do offer some amazing perks to your yard and garden, and once you know these benefits you can plan your garden accordingly.
Here are 6 benefits of planting perennials in your garden:
1. Perennials are often native plants.
In most cases, you can find perennials that are native to your growing area. Native plants are excellent for attracting bluebirds and other wildlife who are more inclined to flock, feed, and nest around native plants.
2. Perennials can be cost-effective.
Instead of buying annual plants that will grow one season and die, consider perennial plants that will grow back for multiple years. With perennial plants you get more bang for your buck, enjoying numerous growing seasons instead of just one.
3. Perennials attract pollinators.
Perennials such as bee balm and coneflowers attract pollinators such as bees, butterflies, and hummingbirds. These pollinators can help your garden flourish and make a huge positive impact on the environment as a whole. A few other perennials that attract bees, butterflies, and hummingbirds include salvia, lavender, daylilies, trumpet flower, and hibiscus.
4. Perennials multiply quickly.
If you have a large garden space to fill, perennials can be your best friend! Perennials will divide quickly, and continue to spread out if they are allowed. Perennials are ideal for filling in garden beds, borders, and entire cutting gardens where you need a bulk of plants.
5. Perennials offer you FREE plants.
Most perennials will need to be divided over time in order to encourage further growth. Each time you divide a perennial you end up with additional, free plants! You can easily replant these flowers in other parts of your yard, or give them away to family and friends. Who doesn’t love free flowers?
6. Perennials can repel some biting bugs.
Perennials such as lavender can help keep biting bugs and mosquitoes away. If you spend a lot of time in your garden, you can surround the border with these repelling plants so that you can enjoy the space in peace. These perennials smell great to humans, but certain biting bugs can’t stand them!
Now that you know all about what makes a plant a perennial, the difference between annuals and perennials, and the benefits of planting perennials, let’s chat about the fun stuff!

How to Plant Perennial Flowers:
Once you have decided which perennials you wish to plant, there are a few planting tips to keep in mind. While planting instructions will vary from plant to plant (i.e. planting depth and spacing) here are a few tips and the answers to commonly asked questions that can help with no matter which plants you decide on.
Where to Buy Perennial Flowers:
First, let’s look at where to buy perennial flowers. You always want to buy from a trusted grower. There are many flies by the night dealers out there who offer unusual and “rare” plant seeds that oftentimes end up being duds. Don’t let this happen to you. Only buy from reputable growers who have a long history in the gardening business.
You can either buy your seeds, bulbs, or live plants via an online retailer, from garden supply catalogs, or at brick and mortar retail stores. If you head to a retail store, you may have better luck going to a store that specializes in gardening supplies. Here you can find a wide assortment and get more personalized help.
Look for a growing guarantee. Many greenhouses and brands offer a money-back promise, where if your plant doesn’t grow you can get a refund. Look carefully at all packaging and hanging tags to see if your plant comes with one of these guarantees. Then, save your receipt in case you need to get a refund.
How to choose the best perennials:
When choosing perennial bulbs or seedlings, take the time to inspect the product. Make sure there is no damage, mold, or evidence of disease such as a white powder coating. For bulbs, they should be firm to the touch, not overly dried out, and in protective packaging. Seedlings should be bright in color, in moist soil, and free from breakage or yellowing/browning.
What kind of soil do perennials need?
Most perennials will benefit from well-drained, nutrient-rich soil. Be sure you choose a planting space that doesn’t accumulate water after a storm. You never want to plant in an area that gets muddy or pools water. Instead, choose well-draining soil and give your soil a nutrient boost such as compost.
Soil should always be loose and never clumpy or compacted. Loose soil gives the roots the chance they need to grow and spread without a great deal of effort.
How do I feed perennials?
Most perennials will benefit from two inches of water per week. Soil should always be moist but never muddy. Water your perennials at the base of the plant so the liquid goes to the roots where it is needed. If you simply spray the entire plant the water may accumulate on the foliage, which can cause burning and rot.
Should I fertilize perennials?
Feeding your perennials fertilizer can help boost their growth. While feeding instructions will be different for each plant, in most cases two feedings a year should be sufficient. Liquid plant food can help give plants the nutrients they need and help you achieve bigger and brighter blooms. Most gardeners like to fertilize right after planting or at the start of the season, and again about 4-6 weeks into the season.
Should I prune perennials?
Perennials can benefit from pruning at the start of the season as well as at the end of the season. Pruning can help your plants grow bushier and keep them from getting lanky and thin.
How do I thin perennials?
After 2-3 years, your perennials may start to overgrow and can benefit from thinning. When you thin out the perennial, you simply dig into the root and dig out new growth sections. When thinning, take care not to break into the original root system. Once you remove the new root system, you can cover the original system up with soil and care for it as usual.
You can then take your thinned out pieces and replant them in other areas of your yard. As mentioned, this is a great way to get free plants for your garden!
Can mulch benefit my perennials?
Yes! You can use mulch to protect the roots of your perennial and hold in moisture. Mulch can help keep roots cool during the hot summer months, and can even help with weed prevention. Simply apply a few inches of mulch around the base of your plant to achieve results.
Mulch can help your perennials in the fall and winter months as well. Cover up your perennials before the first frost of the season to give the plants extra warmth and protection.
How do I protect my perennials from pests?
Slugs, aphids, and other pests can quickly devour your perennials if given the chance. There are some simple steps you can take in order to keep pests off your plants so they have a chance to thrive.
Crushed eggshells around the base of your plants can help keep slugs away. Slugs won’t like the feeling of the shells and will decide to go elsewhere. Another bonus is the eggshells will offer nutrients to the soil. This method is especially effective around hostas, which slugs really seem drawn to. You can also use shallow dishes of beer around the plants, which also work as slug traps.
Making your own DIY pest spray is also an answer when it comes to keeping bugs away. You can make a mixture of 2 cups of water and a tablespoon of dish soap and simply spray on your plants. This is an old fashioned pest remedy that gardeners swear by!
Finally, you can buy over the counter pest solutions. Keep in mind however that these contain chemicals that may repel if not harm your beneficial pollinators such as bees, butterflies, and hummingbirds.
Should I deadhead my perennials?
Yes. In most cases, deadheading your spent blooms can help the plant conserve its energy. Take the time to investigate your perennials daily and simply snap off any spent foliage. You can always toss the dead blooms in your compost pile when done.
As you can see, when it comes to perennials you have so many options! It doesn’t matter what your sun/shade situation is, what kind of space you have, what your gardening skills are, or even what your color preferences are. When it comes to perennials, there is honestly a flower that fits the bill for your needs.
