Gardeners and homeowners love perennial plants; these workhorses in your landscape deliver color and texture in the garden year after year. Unlike annuals, perennial plants live for many years and return after winter’s cold to bloom again.
When shopping for garden plants at your local nursery, you’ll notice the tags often say “annual” or “perennial.” Sometimes, you’ll even see “biennial.” Although colorful, covered in blooms, and so very tempting, annual plants die off every winter. Perennial plants, on the other hand, come back year after year. Biennials, the oddballs of the flower world, live for two years, blooming in the second summer.
The Advantages of Gardening with Perennial Plants
Annual flowers are very inexpensive, and you can find them in many big box and home improvement stores from early spring until late summer. They often only cost one or two dollars, so the idea of filling your flowerbeds with them is hard to resist. But annuals only last a few months, and next spring, you’ll have to start all over again.
Perennial plants cost more and don’t bloom as vigorously as annuals, but they provide more than just color to your garden. They also improve the soil in several ways. Because they live for many years, they develop deep root systems that aerate the soil and provide chambers for water absorption.
These roots reach deep to draw nutrients and bring them back to the top layer as they shed leaves and flowers. These extensive root systems also create the perfect environment for essential microbes to flourish.
Less expensive in the long run
One benefit to the perennial gardener is that this type of gardening can be less costly over the long haul. After all, you only have to purchase them once for years of growth. You'll also find them easy to grow from cuttings. So, if you have one hibiscus, it's relatively easy to propagate several more with the right tools and technique. You can get dozens of long-lived plants from just one initial purchase.
Turning a flower bed in the spring is a lot of work, and that makes yearly soil amendments a much more significant expense. With annual flowers, this results in an annual back-breaking and expensive ritual. Once you've made the initial of effort by preparing the plot for your new perennials, you've done most of the work.
may be some pruning and mulching before the cold sets in, but otherwise, they're worry-free. And because they feature deep root systems, you won't have to set up sprinklers or stand there with a hose every day of the spring to get them established.
Extended flowering season and better variety
Perennial plants also offer more variety throughout the year. Annuals generally only have one growing season to accomplish the job of reproducing themselves by flowering and going to seed. Most do this during the same time of year, which is mid to late summer.
Perennials, which are under much less pressure to reproduce right away, have different blooming seasons. So, you’ll be sure to enjoy the fruits of your labor from early spring through frost. In fact, some perennials feature evergreen foliage, which means you'll be enjoying them all year round.
Choosing the Best Perennial Plants
When selecting plants to add to your garden or landscape plan, however, you’ll need to consider several factors. For outdoor gardens, your hardiness zone will play a large part in determining which perennials will work best for you.
And some plants are perennial only in specific zones. The South enjoys flowering plants that remain evergreen throughout the year or grow back vigorously after a freeze. Northern states, on the other hand, enjoy the perpetual return of bulb flowers like daffodils, tulips, and irises, that require a low-temperature dormant phase to bloom the next year.
Most plants have a preference for temperature, hours of daylight, and moisture levels. Other, less simplistic considerations are salt tolerance and acidity preferences. If you have a greenhouse or use containers, you may be able to extend the life of otherwise cold-tender plants. And Southern gardeners have the option of digging up bulbs and storing them in the refrigerator for a few months before replanting.
How to Pick the Best Flowering Perennial Bushes
If you’re aiming for dramatic beauty for your lawn, nothing makes a statement like flowering bushes. These perennial plants provide color for any landscape plan, and many attract wildlife like birds, butterflies, and bees.
