Is My Sunflower An Annual Or A Perennial Sunflower

By: Heather Rhoades

You have a beautiful sunflower in your yard, except you didn’t plant it there (probably a gift from a passing bird) but it looks nice and you want to keep it. You may be asking yourself, “Is my sunflower an annual or a perennial?” Read on to learn more.

Annual and Perennial Sunflowers

Sunflowers are either an annual (where they need to be replanted every year) or a perennial (where they will come back every year from the same plant) and telling the difference is not that hard if you know how.

Some differences between annual sunflowers (Helianthus annuus) and perennial sunflowers (Helianthus multiflorus) include:

  • Seed heads – Annual sunflowers can have either large or small seed heads, but perennial sunflowers have only small seed heads.
  • Blooms – Annual sunflowers will bloom the first year after being planted from seeds, but perennial sunflowers grown from seed will not bloom for at least two years.
  • Roots – Perennial sunflowers will have tubers and rhizomes attached to their roots, but annual sunflowers just have the typical string like roots. Also, annual sunflowers will have shallow roots while perennial sunflowers have deeper roots.
  • Post winter emergence – Perennial sunflowers will start up from the ground in early spring. Annual sunflowers growing from reseeding will not start to show up until late spring.
  • Germination – Annual sunflowers will germinate and grow rapidly while perennial sunflowers grow much more slowly.
  • Seeds – Non hybridized perennial sunflowers will have relatively few seeds since it prefers to spread through its roots. The seeds also tend to be smaller. Annual sunflowers spread through their seeds and, because of this, have many large seeds. But because of modern hybridization, there are now perennial sunflowers that have more seeds on their flower heads.
  • Growth pattern – Annual sunflowers tend to grow from a single stems spaced out from each other. Perennial sunflowers grow in clumps with many stems coming out of the ground a tight clump.

Top Perennial Plants For Wildflower Meadows

After seeding and tending wildflower meadows for over 20 years, we've learned a lot. Most of our work has been done in Vermont, which means we had to deal with Zone 4 weather, but by working with wildgardeners from all over North America, we also learned which plants do best in various areas.

Below are my recommendations, based on actual growing almost anywhere. You can try almost any perennial in your meadow, of course. But these are all plants I promise you will be major colormakers, and return for you year after year. They're all either unhybridized wildflowers or close hybrids, and that's what you want for a natural wildflower garden. (Of course, check the zone hardiness before you buy your plants.)

Helianthus "Lemon Queen" is a large, fast-growing perennial sunflower that reaches heights of 6 to 8 feet and widths of 3 to 4 feet. The plant produces masses of 2-inch, pale lemon-yellow, semi-double blooms with dark brown centers. Blooms appear in midsummer and last six to eight weeks. Helianthus "Lemon Queen" is perennial in USDA zones 4 through 9.

Helanthus x multiflorus includes a number of attractive perennial sunflower varieties, each displaying masses of colorful, early- to late-summer flowers on fuzzy stems measuring as tall as 4 to 5 feet. Varieties include the intense gold, double-flowered "Lodden Gold" "Capenoch Star," with bright yellow, single flowers and "Soleil d’Or," with vivid yellow, semi-double blooms.

A List of Perennial Flowers For Your Garden.

Perfectly Planned Perennial Garden With Annuals Tucked In Between.

The following list of perennial flowers will help you choose just which permanent plants you want to invite into your garden to stay. When planning your perennial garden, keep in mind the fact that some of these plants could be around for many years to come. These are the plants which will live from three to thirty years or more, depending on how happy they are.

So even though you don't need a pencil and paper to map out your garden, it's a good idea to give it some thought before you go out and buy what could be a quite expensive plant. You need to know how to care for it so that your investment is not wasted - and where to put it.

If you are just starting out and have a large, bare plot to cover, it can be quite overwhelming, but imagine a garden without any perennials . It's worth it. Of course the main things to plant first are the Trees (if you want some), then the tall Woody Perennials such as Roses, Rhododendrons and Hydrangeas, and then the smaller Herbaceous Perennials. Herbaceous Perennials are the ones that are easiest to deal with and move around if you get them wrong eg. Chrysanthemums. The Herbaceous Perennials are the ones which die back each year to ground level, and then bloom again in the spring. The best examples of these would have to be the Bulbs.

After you know what is going where, it's time to think of the Annuals which can be tucked in between the Perennials. When planning your garden, keep in mind the fact that Herbaceous Perennials fit well with evergreen shrubs and small trees and bushes. See more information on this site: Perennial Flowers.

The following List of Perennial Flowers contains flowers which are common and easy to grow. In some cold areas they are only grown as Annuals. The information will be on the tag. I hope the images at the top of each page will give you some ideas about your perennial flower garden design. Check back here often as I add what I find because this list is by no means complete!

Welcome to our gallery of alluring perennial gardens!

It’s nice when your hard work in the garden pays off. It’s even better when those rewards come back time and time again. When planting perennials you can see your efforts pay dividends each year as the flowers perk back up in the spring, returning with blooms of color.

Any garden you invest in will increase the beauty, curb appeal, and value of your property.

With a perennial garden (for both perennials for shade and perennials for sun) most of the work will be devoted to the initial landscaping and planting of the flowers. From then on, with proper maintenance, you will have a fabulous garden that returns year after year.

The alternative to perennials are annuals. Annuals are flowers that die out each year and need to be replanted.

What are the pros and cons of having a perennial gardens?

  1. No replanting – Perennials come back every year and do not need to be replanted. This is a time and money saver. If you maintain your plants they will come back year after year to brighten up your yard.
  2. Expansion – With enough care your flowers will not only return every year, but may even multiply and fill out your flowerbed. This means that a few plants can potentially turn into an entire garden over time.
  1. Overwhelming your garden – Because perennials spread if you do not thin them out each spring they can take over your garden space. They can also overwhelm other plants and become hard to manage if you do not keep up on maintenance.
  2. No change – When your perennials return each year, the look will be very similar to the look of the year prior. When you set your perennial design it should be one that you are going to be happy with multiple years in a row. If you prefer change it may be more of a chore to change out perennials versus annuals.
  3. Shorter bloom – While perennials do return every year, the amount of time during which they are blossoming is shorter than annuals. Your garden will be colorful for a shorter period during the year than if you take the time to replant annuals.

When installing a garden, size is the most important factor when it comes to cost. If your garden is going to be smaller than 500 square feet you can expect to spend around $480 or less, depending on how small your garden is. Gardens between 500 and 1,000 square feet cost around $600, while those around 1,000 to 2,000 square feet run upward of $830. Price continues to increase with size. Extra features such as irrigation will increase your costs as well. (Source: Red Beacon)

Planting Perennial Sunflowers

Sow perennial sunflower seeds either in the fall or in the spring after the last frost. (Get seeds here.)

If sowing in the spring, the seeds must first be cold stratified, which means they need a period of cold to germinate.

To cold stratify the seeds indoors, start about 8-10 weeks before your spring frost date. Put seeds in a ziplock bag with moistened seedstarting medium, and store in the refrigerator for 30 days. Check the seeds weekly, and if they begin to germinate, it’s time to plant them.

Sow the stratified seeds indoors under lights. For details on seed starting, see my step-by-step guide. Plant them outside after the danger of frost has passed.
