Impatiens are one of the rare annual plants that will provide colorful blooms in shady gardens—so they’re also perfect for hanging baskets or containers on porches. Learn how to plant, grow, and care for impatiens.
About Impatiens
Impatiens are very popular as both a bedding and hanging plant. Also called “Busy Lizzies,” these beauties are low-maintenance and don’t even need pinching! The genus name, Impatiens, is a Latin word describing how its seeds shoot out of its pods when ripe (the slightest touch can make a ripe impatiens seed pod burst open and scatter its contents).
Ornamental impatiens are primarily from two groups, Impatiens walleriana and New Guinea impatiens, Impatiens hawkeri. The two look different, but growing them is pretty much the same. I. wallerina cultivars are less tolerant of sunshine than the New Guinea hybrids, and the latter has larger foliage.
Of short to medium height, most impatiens varieties grow 8 to 15 inches tall, although some types reach 30 inches. They are perennials in frost-free areas but are grown as annuals or houseplants everywhere else.
Use impatiens for a splash of all-season color in any area that receives partial shade. Because of their shallow root system and low height, impatiens are ideally suited to containers like hanging baskets, window boxes, or deck railing planters. They also work well in the “filler” role in larger containers.
Growing
Impatiens are not fussy and, if planted in the correct location, will thrive with little effort–one of the reasons they are popular.
- The most important thing to remember about impatiens is to water them regularly. Keep the soil moist but not too wet. If the plants dry out, they will lose their leaves. If you over-water the plants, it encourages fungal diseases.
- Container-grown impatiens will benefit from fertilizer applied every two weeks when watering.
- Deadheading, while not strictly necessary, will improve their appearance and encourage more blooms.
Overwintering Impatiens
Impatiens are hardy in zones 10-12, but even a light frost will kill them. If you have a favorite color you’d like to overwinter, either take cuttings or dig up the plant and bring it inside. Depending on your available sunlight and day length, a grow light may be necessary.
Propagating Impatiens
Impatiens can be easily propagated from stem cuttings–a great way to get more of a favorite color or gift it to a friend. At the end of the growing season, taking cuttings and growing them over the winter may be easier than digging up entire plants and trying to keep them alive in the house.
- Inspect your plant to make sure it is pest-free.
- Sanitize your shears with alcohol.
- Choose several strong stems and snip them 4-6 inches below the bloom.
- Remove the flower and all but the upper one or two pairs of leaves.
- Place the cuttings in a clear glass container filled with clean water. If your water is treated by your municipality, let the water sit on the counter for 24 hours first to allow most of the chemicals to dissipate.
- In a week or two, when fine white roots appear, transition the cuttings to the soil in one of two ways:
- Plant them in individual pots filled with moist potting mix.
- Add a bit of potting mix to your glass container daily until it is completely filled with soil after a week. After filling the jar with soil, remove the plants and repot.
- Lollipop series (I. walleriana) ‘Fruit Punch Rose’ is a compact, well-branched variety with superbly vivid colors.
- Tom Thumb Series (I. balsamina) is a dwarf variety with large, double, brightly colored flowers.
- Beacon® impatiens are highly resistant to downy mildew and will keep blooming reliably until frost.
- Swirl Series (I. walleriana) has pretty pink and orange flowers with petals in red.

I just hung two containers of impatiens last week. They are in the shade all day. I water them daily and fertilized them last week after buying them. They do not seem to be doing well. The blossoms are smaller and not as open. Is this too much shade for them? Do they need some sun? I am watering them daily.
Thanks, Bill
Bill, get your plants into the sunshine as soon as possible! Impatiens need full sun—that’s six to eight hours per day. Without it, they will surely fail.
And once in the sun, water them to be damp but do not be afraid to let them dry out for short periods between waterings. All wet all the time is not good.
Hope you can save them!
I WOULD LIKE TO PLANT SOME IMPATIENS FOR A BURST OF COLOUR IN OUR FLOWER BED WHICH JUST HAS SOME BUSHES IN IT. IT GETS QUITE A BIT OF SUN MOST OF THE DAY,I HAVE HEARD THAT THERE IS A PLANT THAT CAN TAKE THE SUN, IS THIS CORRECT? I WOULD LIKE THEM TO STAY NEAR THE GROUND, NOT TOO HIGH, SO HOW FAR APART SHOULD I PLANT THEM? THANK YOU.
After doing some research, Ive realized I may be doing this wrong! I planted a full pot of impatiens, but the poor things sit under the sun all day! I water them every early morning..they seem to be doing ok, especially since Ive gotten rid of my garden slug problem!
The flowers do fall off rather easily..should I get them some shade for better blooming?
Impatients do grow well in shade but if your pot in the sun is healthy and doing well, there is no need to change location. You can experiment by planting some in a different pot and putting it in the shade to see if they will bloom more.
dont know why but the floweres were not open and fell off died why
I water my impatien flower everyday, but the tips of the leaves and flower stem are turning brown. Is this because I gave the plant too much? Or too little? How much water is enough? What is the exact amount (measurement) of water does it need?
You might be watering them too much. Let the soil dry out between waterings. It’s impossible to give an exact amount. Water when the soil is dry.
Some impatiens plants are also experiencing a downy mildew that causes severe defoliation and flower drop. Nursery and landscape plants were affected by the plants. We do not know if your plants are experiencing that. But you can learn more here: http://www.extension.umn.edu/garden/yard-garden/flowers/managing-impatiens-downy-mildew-in-landscape/
I have cared for my son's imapatien since he died 18 months ago. A month ago, it was big, leafy and blooming, then it started dropping leaves. Looked like little webs and mites on stems. Sprayed a natural house plant insecticide, but leaves still wilt and fall off. Please, help me save Nicky's plant, which he brought home for Mother's day when he was 7 years old.
It’s hard to get rid of spider mites. Check for reinfestation. Organic horticultural oils and soaps do help. Remove infested leaves and maybe cut some of the damaged stems.
