Are Impatiens Annuals or Perennials? A Gardener’s Guide

Are Impatiens Annuals or Perennials?

Impatiens are technically perennials, but they are primarily grown as annuals in most regions.

In USDA growing zones 10 and 11, they can be overwintered outdoors or grown as houseplants.

However, in colder climates, they are typically planted in the spring and treated as annuals.

Key Points:

  • Impatiens are technically perennials, but commonly grown as annuals.
  • In USDA growing zones 10 and 11, they can be overwintered or grown as houseplants.
  • In colder climates, impatiens are typically treated as annuals.
  • Impatiens are primarily grown as annuals in most regions.
  • They can be planted in the spring and enjoyed for one season.
  • In some regions, impatiens can be grown as perennials if appropriate conditions are provided.

Did You Know?

1. Impatiens, also known as busy Lizzies, are primarily a popular annual plant choice in many gardens worldwide. However, they can be successfully grown as perennials in certain regions with mild, frost-free winters.

2. The genus name “Impatiens” is derived from a Latin word meaning “impatient” or “eager,” which refers to the plant’s unique seed dispersion mechanism. When the seed pods are ripe, they explode when touched, sending the seeds flying up to several feet away.

3. There are over a thousand known species of Impatiens, but the most commonly cultivated species is Impatiens walleriana. Its vibrant and abundant flowers have made it a favorite choice for hanging baskets, containers, and flower beds.

4. Among the various colors of Impatiens, the color blue is notably absent. While Impatiens flowers can be found in shades of white, pink, orange, and red, true blue flowers are not naturally occurring in this species.

5. Impatiens are native to the tropical and subtropical regions of Africa and Asia. They were introduced to Europe in the 19th century as ornamental plants and gained immense popularity due to their ability to thrive in shade and produce colorful blooms even in low light conditions.

Impatiens: Annuals Or Perennials?

Impatiens, with their vibrant blooms and lush foliage, are beloved by gardeners around the world. But are they annuals or perennials? The answer is a bit more complex than a simple yes or no.

Impatiens are technically perennials, but only in USDA growing zones 10 and 11, which encompass warm climates. In these regions, impatiens can be grown year-round, and with proper care, they can thrive and continue to bloom for several years.

However, for most gardeners in regions outside of zones 10 and 11, impatiens are grown as annuals. These gardeners typically plant impatiens outdoors after the threat of frost has passed, and enjoy their colorful display throughout the spring and summer months. In colder climates, impatiens cannot survive the winter frost, so they are replanted each year.

Growing Impatiens: Tips And Information

Impatiens, also known as Busy Lizzies, are native to tropical and subtropical mountain forests in Central America, Africa, Madagascar, southeast Asia, and other areas. They thrive in partial to full shade, making them an ideal choice for shady gardens or areas with filtered sunlight. It is important to wait until the soil has warmed to at least 60 degrees Fahrenheit before transplanting impatiens. When planting, they should be spaced 10 to 12 inches apart to allow for proper air circulation and prevent overcrowding. Pinching back the stems after planting will encourage bushy growth, resulting in a fuller and more vibrant display of flowers.

Impatiens can also be grown in containers, provided they have good drainage and are filled with a standard commercial potting mix. However, container-grown impatiens require more fertilizer and water than those grown in the garden. It is recommended to fertilize with water-soluble fertilizer every two weeks for optimal flowering. Additionally, impatiens need at least two inches of water per week, potentially more in hot weather. Window boxes and hanging pots may require daily watering in high temperatures.

In summary:

  • Impatiens thrive in partial to full shade.
  • Wait until the soil has warmed to at least 60 degrees Fahrenheit before transplanting.
  • Space impatiens 10 to 12 inches apart for proper air circulation.
  • Pinch back stems after planting for bushier growth and more vibrant flowers.
  • Container-grown impatiens require more fertilizer and water than those in the garden.
  • Fertilize with water-soluble fertilizer every two weeks for optimal flowering.
  • Impatiens need at least two inches of water per week, potentially more in hot weather.
  • Window boxes and hanging pots may require daily watering in high temperatures.

Best Varieties Of Impatiens For Different Conditions

With over a thousand varieties of impatiens available, gardeners have a wide range of choices when it comes to selecting the best variety for their specific conditions. Some recommended varieties of standard impatiens include ‘Imara XDR’ and ‘Beacon’, which are known for their disease resistance. For those seeking a hybrid between New Guinea and standard impatiens, the ‘Bounce’ series is recommended, as it is resistant to downy mildew.

If you have a sunny spot in your garden, the ‘SunPatiens’ series is a great option, as these impatiens thrive in full sun and produce large flowers. New Guinea impatiens, such as the ‘Celebration’ series, require more direct sunlight than standard impatiens, making them perfect for slightly sunnier areas. It is important to note that New Guinea impatiens can tolerate full sun, but they will need extra moisture to thrive.

Frequently Asked Questions

How do I know if my impatiens are annual or perennial?

One way to determine if your impatiens are annual or perennial is by observing how they respond when you cut them back. If you trim the plants back to about 6 inches and new growth emerges within a few days, it is likely that they are perennials. Perennials have a strong resilience and will quickly surge back with fresh growth and flowers. This regrowth will indicate that your impatiens are capable of growing back year after year, distinguishing them as perennials.

On the other hand, if cutting back your impatiens does not result in new growth and they do not regenerate, it is more likely that they are annuals. Annual plants have a shorter lifespan, usually lasting only a single growing season, so they may not show the same regrowth and vigor as perennials. By observing the response of your impatiens to trimming, you can determine whether they are annuals or perennials and plan your gardening accordingly.

Do impatiens like full sun or shade?

While impatiens can tolerate some sun exposure, they generally prefer partial shade for optimal growth. The ideal conditions for impatiens include sites with filtered sun for 2 to 4 hours a day or areas that receive morning sun and afternoon shade. It is worth noting that impatiens can adapt to heavy shade, although in such locations they may grow taller and produce fewer blooms compared to plants cultivated in partial shade.

Do impatiens last all summer long?

Impatiens, the beloved annuals of shade gardens, indeed have the ability to last all summer long, making them an excellent choice for those seeking continuous blooms. Besides their vibrant assortment of colors, impatiens are known for their unmatched bloom power. With their prolific flowering capabilities, they can provide an ongoing display of blossoms throughout the entire growing season without the need for deadheading. Consequently, these hardy plants can grace your garden with their vibrant beauty all summer long without showing signs of weariness.

Thanks to impatiens’ remarkable endurance and self-sustaining nature, they are able to thrive and bloom tirelessly throughout the summer months. These shade garden classics offer a convenient and low-maintenance option, as they do not require regular deadheading to keep their blooms coming. As a result, impatiens prove to be a reliable and long-lasting choice for those seeking a continuous floral spectacle in their gardens from early summer to the brink of fall.

Are impatiens hardy annuals?

Impatiens are not hardy annuals, as they are perennials in frost-free regions but typically grown as annuals or houseplants in other areas. With a height range of 8 to 30 inches, most impatiens varieties are of short to medium stature. Although they can withstand frost-free conditions and thrive as perennials, their cultivation as annuals is more common in regions where frost occurs.
