The epitome of the shade garden plant, impatiens have been used for years for their bloom power and wide variety of colors. These tropical plants are blooming powerhouses and will fill a space with blossoms as long as there is no frost. They can bloom for a whole growing season, and they don’t even need maintenance, like deadheading, to keep up! More recently, many impatiens have become susceptible to downy mildew, a devastating fungal disease, so make sure to look for resistant varieties.
Impatiens are great plants if you want loads of color with little effort. Most commonly, impatiens come in softer pastel shades, but some tropical species come in warm colors like yellow, coral, and orange as well. With their quick growth habit, impatiens are great fillers for both garden beds and containers. The soft color palette allows them to blend well with pretty much anything.
Impatiens Care Must-Knows
You might think there would be some catch with a plant this floriferous and easy to grow—but there isn’t! An important thing to remember, however, is that impatiens are tropical plants. Once the first frost comes, your impatiens will turn to mush, so if you are planning on overwintering some indoors, make sure to bring in any pots or take any cuttings before the temperatures get too low.
When you are planting impatiens, give them rich, well-drained soils. In containers, any general-purpose potting media will do. In the ground, if you have heavy clays, it is best to add some organic matter like compost or peat moss to loosen it up and add nutrients. Impatiens are not very tolerant of drought, and during long dry spells the plants will quickly wilt. Luckily, they are very quick to bounce back once watered. So if you see an impatiens that looks beyond hope, give it some water and watch—in a very short time, its will look good as new.
There are a few things to watch for and to be aware of when growing impatiens. Recently, a major problem has been a nasty fungus called downy mildew. Downy mildew can be tricky to identify in the early stages. It typically begins by causing leaves to yellow and drop off or die. Eventually, this can become more dramatic, and portions of the leaves will erratically become brown and dead. You can identify downy mildew by finding their trademark downy white spores on the undersides of leaves. Downy mildew is a tricky disease to control, so the best way to avoid it is to choose resistant varieties when planting. If you do find powdery mildew, destroying the plants and any debris around the plants to prevent it from infecting any other plants is the best course of action.
Because of the devastating affects of downy mildew on such an important horticultural crop, there has been quite a bit of research on new hybrids. Many of these new hybrids are more similar to new guinea impatiens, which are not affected by powdery mildew. This has created some beautiful new cultivars, many of which boast the best of both worlds, including larger plants, more sun tolerance, and disease resistance. Be sure to look for these disease-resistant varieties as you shop for plants in the spring.

Plant Impatiens With:
Browallia earns its nicknames of amethyst flower and sapphire flower for the richness of its small blue flowers, which pop out like jewels against the bright green of its foliage. A tidy mounding plant, it’s great in containers or planted as edging in a neat row at the front of the border. Plant in a shady spot in spring after all danger of frost has passed. It likes rich soil high in organic matter, so add some compost at planting time. Keep well watered, and mulch to keep soil cool and moist. It may not flower in areas where summers are very cool. It may overwinter in the warmest regions (Zones 10-11), especially if covered with loose autumn leaves, straw, or any other light, airy winter mulch.
Talk about foolproof: Annual begonia is about as easy as it gets. It does well in a variety of conditions, but to keep it its most luxuriant best, give it light shade; rich, well-drained soil; and ample water. It also loves plenty of fertilizer, so be generous. Plant annual begonias in spring after all danger of frost has passed. No need to deadhead this flower unless you want to because it’s “self-cleaning.”
Tired of impatiens? Try the enchanting wishbone flower, also dubbed clown flower for its vividly marked flowers that are said to resemble the face of a clown. It’s a wonderful, relatively new choice for shade. The flower shape resembles tiny snapdragons, with mouths opening wide and showing off delicate throats marked with a contrasting color. Torenia grows easily from seed sown indoors in pots or outdoors in the ground. This little clown flower blooms nonstop until frost.

How To Grow New Guinea Impatiens
Colour your summer with this versatile Impatiens; in the garden or indoors
The New Guinea impatiens are a great value bedding plant, they flower all summer into autumn and they make quite a large plant so you don’t need as many to have a good show. They have become a lot more popular in the last few years as they don’t get the highly contagious downy mildew that has plagued Busy Lizzies. Unfortunately Busy Lizzies are one of the few summer bedding plants that will thrive and give you some colour in a shady spot. The New Guineas won’t thrive in the shade but do need to be out of the midday sun. The flowers are much larger than Busy Lizzies and come in shades of orange, red and lavender, and also pure white. As their name suggests they are a tropical plant native to Papua New Guinea and the Solomon Islands.
Pick a spot out of the midday sun but where they receive morning and late afternoon sun. If planting in the garden you need good moisture retentive, but not soggy, fertile soil. If you are growing it as a houseplant don’t place it in a south facing window, it will last a lot longer if shaded from the midday sun and kept on the cool side.
If planting in containers use good quality peat-free compost with slow release fertiliser and water retention gel added. When planting in the garden add some balanced fertiliser such as Growmore or blood, fish and bone. They make a thick mound about 30cm (12”) in diameter so don’t plant them too close together.
They won’t thrive if they become dry so make sure they are kept well-watered, especially in a drought. Feed every week with a high potash fertiliser, such as Tomorite, if you feed with a nitrogen based fertiliser you will end up with a big plant but not many flowers. Deadhead regularly to encourage it to go on producing more flowers. Treat the houseplant just the same as you would in the garden.
Pests and diseases
They will suffer from slugs and snails so take the usual precautions.
Mildew can also be a problem so make sure you don’t let them dry out and ensure there is a good airflow around them.
Q: I have some particularly beautiful impatiens that I want to grow next year. Is there any way to keep them alive indoors over the winter?
A: There are three ways to keep your impatiens. You can simply dig a clump of the plants and keep them in an indoor pot for the winter. You’ll need to grow them in plenty of light to keep them healthy. Another option is to take 6 inch long stem cuttings and root them in water. When the roots have grown one half inch, transplant the cuttings into small pots filled with potting soil. The third choice is to collect the impatiens seeds and plant them next year. You could either start them indoors in March or plant them outdoors in late April. If you plant the seeds, remember that they need light in order to germinate. Sprinkle the seed on top of the soil but do not cover it with more earth.
Q: What is the best winter care for my New Guinea impatiens?
A: Unlike geraniums, New Guinea impatiens and common impatiens can not be forced into dormancy for the winter. They must be brought inside and cared for as a house plant. To make the job easier, prune the plants back now so they will be correctly sized for indoor life. If they are planted in the ground, dig them and put them in pots now. Put the plants in deep shade outdoors until fall so they won’t suffer “light deprivation” when they go indoors. Then, place them in your sunniest window and water only when necessary during the cold weather.
