Learn About Perennials

We've provided a reference section below for you to enjoy. Get help figuring out what to plant so your garden is constantly blooming, or find out how to space a garden, or discover how to build a rain garden. Then take a look at our wide variety of helpful lists to make sure you get the plants that will work in your specific situation.

Why Latin Names for Plants?

Why does Northern Sunset use those confusing, scientific names for their plants?

You will find that all Northern Sunset Perennials have their Scientific, or Latin, name listed prominently. We understand that Latin names, with their genus, species and cultivars may seem very confusing. Not to mention their pronunciation!! It was confusing for us too, in the beginning.

However, the pros outweigh the cons when it comes to using scientific names. In truth it is the only way to make sure you are getting the plant that you want. Latin is a universal language in the horticultural world. If you know a plant's Latin name, you could order it from Russia and they would know what plant you want!

However, if you use the common name of, let's say, Black-eyed Susan, you could get one of 5 very different plants. It could be either:

  • A biennial native plant that seeds prolifically, Rudbeckia hirta
  • Another native, Rudbeckia triloba, a perennial, also known as Brown Eyed Susan
  • A perennial, Rudbeckia fulgida speciosa, also known as Showy Coneflower
  • A cultivar, Rudbeckia fulgida Goldsturm
  • A vine, Thunbergia alata
  • Or a daylily variety, Hemerocallis x Black Eyed Susan
We encourage you to be an informed consumer. By doing a little research, either online or by using a good reference, you can be sure that the plant you want is the plant you get. A good Internet search engine can be used with Latin and/or common names, and the result may give you a picture to boot. A good reference book is a great way to spend a cold winter evening by the fire, dreaming of the beautiful garden you will create in the spring.

And, by the way, the easiest way to figure out how to pronounce a scientific name is to remember that there are no silent letters, every one is sounded out.


What's Bloomin' Each Month?

Create a garden that blooms continuously during the growing season. Determine the light your garden will receive and then review our list of what blooms each month, by light preference and height. Then look for these plants in your local garden centers! Don't be confused by the Latin names -- your garden center will assist you in locating the plant you need.

Our list has been designed to complement the Northern Sunset color system: Periwinkle Blue for Full Shade, Mint Green for Part Shade, Warm Apricot for Part Sun, and Sunny Yellow for Full Sun.

Select the proper guide for your garden and enjoy a quick reference to bloom time and height. With the right plant in the right place, perennials can give any garden constantly changing colors and textures.

We have created some additional tools to help you determine the perennials that are right for your garden. As you choose the links below in our chart, please note our designations for bloom times, re-blooming perennials, and height categories.

Bloom times roughly correspond to the months of the garden season beginning with March and going through October. Perennials can vary in bloom time from year to year by as much as two weeks, depending on weather conditions.

Longer bloom times have been designated by an asterisk (*). Each asterisk indicates an extra 2-4 weeks of bloom.


Re-blooming perennials are indicated by a lowercase, superscript r, as you see in the Iberis s. Autumn Beautyr

Height has been divided into 5 categories:

    Groundhugger Small Medium Tall Vine
    2"-12" 10"-24" 18"-36" 30"-9' 48"-75'


We hope this information, along with the Northern Sunset System for Success, and of course, the quality of Northern Sunset helps you achieve your most beautiful garden ever!

Rain Gardens are one of the newest garden types around. Not only are they beautiful, they filter rainwater, help reduce runoff and attract wildlife like birds and butterflies!! They are easy to build and maintain, too.

There is lots of information about rain gardens on the web. Here are a few of our favorites, along with a list of perennials suitable for rain gardens both formal and informal.

Salt Tolerant Perennials

The cold, snowy and icy winters of the Midwest require the use of salt to clear roads and sidewalks. Salts accumulate over time in the soil along roads, sidewalks and driveways. Plants subjected to these salty situations may not be able to take up water and may be damaged or even die, because of a sodium induced 'drought'.

What Grows Under the Black Walnut

If you have one in your yard, you may have observed the difficulty in finding plants to thrive under their branches and in their root zone. The root, bark and seeds of the Black Walnut (Juglans nigra) gives off a chemical, called juglone, which is toxic to many plants.
