Types of Impatiens

There are several main types of Impatiens that are popular for their colorful flowers and attractive foliage:

Impatiens balsamina (Garden Balsam): The plant produces attractive, brightly colored flowers that can be single or double, in shades of pink, red, purple, and white.
Impatiens capensis (Orange Jewelweed): This is a North American native annual plant that reaches a height of 2 to 5 feet (60-150 cm) and produces orange, trumpet-shaped flowers with red or orange spots from mid-summer to early fall.
Impatiens niamniamensis (Parrot Impatiens): This unique variety has exotic, parrot-like flowers that are very distinctive.
Impatiens walleriana (Busy Lizzie or Balsam): This is the most common type of Impatiens and comes in a wide range of colors, including pink, red, white, and purple. Walleriana cultivars typically need to be grown in the shade.
New Guinea Impatiens (Impatiens hawkeri): These are larger than the common Impatiens and have striking flowers and foliage. New Guinea Impatiens are often more sun tolerant and have more resistance to mildew diseases. They also have larger, showier foliage than walleriana cultivars. They can tolerate more sun than the traditional varieties but still prefer partial shade.
SunPatiens (Impatiens hybrid): A hybrid between traditional Impatiens and New Guinea Impatiens, SunPatiens can tolerate both sun and heat better than other types. As a result, they’re perfect for Florida and flower year-round. Like New Guinea impatiens, SunPatiens are unaffected by downy mildew and require regular watering.

Both are grown for their brightly colored flowers.

Planting Impatiens

Impatiens are typically planted in the spring after the danger of frost has passed.

Sunlight: Impatiens thrive in partial shade, making them ideal for planting under trees or in areas that receive dappled sunlight. Some varieties can also tolerate full shade, while others can handle a bit more sun exposure, especially in cooler climates. New Guinea impatiens are much more sun tolerant than Walleriana.
Soil: Impatiens prefer well-draining, nutrient-rich soil with a slightly acidic to neutral pH (between 6.0 and 6.5). Soil must be well drained. To improve drainage, compost or sand can be incorporated into heavy soils. Impatiens require a lot of moisture so soil must also be able to retain water well in addition to having good drainage.

Planting instructions:

Gently remove the plant from its container, being careful not to damage the roots.
Place the plant in the hole so that the top of the root ball is level with the surrounding soil.
Water the newly planted Impatiens thoroughly and keep the soil consistently moist, especially during the first few weeks as they establish themselves.
If planting in the garden, plants should be spaced at 8 to 12 inches.

Proper planting ensures healthy growth.

Caring for Impatiens

Caring for Impatiens is relatively easy, as they are low-maintenance plants that can provide a burst of color in your garden, especially in shaded areas.

Watering: Impatiens are moisture-loving plants that require frequent watering and watering needs will differ depending on the environment the plant is placed into. Impatiens require consistently moist soil, so be sure to water them regularly. A plant in full sun will require more water than one in the shade and plants grown in containers will require much more frequent watering than those grown in garden beds. Keep the soil evenly moist but not soggy, as both overwatering and underwatering can cause problems. Only water when the top 1-2 inches of soil is dry if growing in a garden bed. Water daily for container plants but make sure the container has drainage holes at the bottom to allow excess water to run out. Hanging baskets will require watering at least once a day and should also have drainage holes. If the plant starts dropping or losing leaves, that is a sign it is not getting enough moisture.
Fertilizing: Incorporate a granular general-purpose fertilizer with equal amounts of nitrogen, phosphorus and potassium into the soil at the time of planting. Fresh potting soil has all the nutrients your plant needs, so as long as it’s refreshed yearly, you shouldn’t need to use fertilizer. After planting, impatiens should be fertilized monthly using either a granular, water-soluble or a foliar fertilizer that contains higher amounts of phosphorus than nitrogen to promote new flower development over foliage growth. When using a granular fertilizer, be sure to incorporate it into the soil by watering or time your fertilizing schedule with natural rain events. Feed with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season. This will encourage healthy growth and more abundant blooms.
Pruning: Although pruning is unnecessary, you can pinch plants back if they become tall and leggy to encourage bushier growth. Your plants will quickly respond with a new flush of blooms. With walleriana cultivars, the top 2 inches of the plant can be clipped off right above a leaf node when it is about 6 inches tall. This will result in a bushier plant.
Deadheading: Removing old flowers is not necessary and will not promote new flower growth. Although deadheading is not necessary for all varieties, it can help promote more blooms and maintain a tidy appearance.
Repotting: New Guinea Impatiens should be repotted after it doubles in size or once a year, whichever comes first. To replenish this plant's nutrients, repot your New Guinea Impatiens after it doubles in size or once a year-whichever comes first.

To keep impatiens blooming, ensure they receive proper care, including consistent moisture (but not overwatering), well-draining soil, and a balanced, slow-release fertilizer applied according to package instructions.

Propagating Impatiens

Impatiens can be propagated through two primary methods: from seeds or from stem cuttings.

From Seeds:

Sow the Impatiens seeds on the surface of the soil, gently pressing them in.
Place the trays or pots in a warm, well-lit location, with temperatures around 70-75°F (21-24°C).
Impatiens seeds should germinate within 10-20 days.

From Stem Cuttings:

Choose healthy, disease-free Impatiens plants, and take 3-4 inch (7.5-10 cm) long stem cuttings from their tips. Make a cut just above the node. New Guinea Impatiens can be propagated by the stem method. Make a cut just above the node.
Make a hole in the potting mix with a pencil or your finger, and insert the cut end of the stem cutting into the hole.
Place the pot in a warm, bright location out of direct sunlight.
Roots should develop within 3-4 weeks.
Check for root development by gently tugging on the cutting; if it resists, roots have formed.
Remove the plastic covering, and let the cutting grow for another week or two.

Pests and Diseases

Impatiens are susceptible to several pests and diseases. Regular monitoring and prompt action can help minimize the impact of pests and diseases on your plants.

Aphids: These tiny insects suck sap from the plant, leading to distorted leaves, stunted growth, and the spread of viruses.
Spider mites: These tiny mites can cause yellowing and stippling on leaves, eventually leading to leaf drop.
Whiteflies: These small, white insects can cause yellowing and curling of leaves, as well as transmit viruses.
Downy mildew: This fungal disease causes the yellowing of leaves, followed by white, downy growth on the undersides. It can lead to defoliation and even plant death.
Powdery mildew: This fungal disease appears as white, powdery growth on leaves and can cause distortion and leaf drop.
Root rot: Overwatering or poorly draining soils can cause root rot, leading to yellowing, wilting, and plant death. Overwatering and root rot are the most likely cause of problems in New Guinea Impatiens, since they are sensitive to wet soil. The leaves may also appear to be curling or drooping.
Botrytis blight: This fungal disease can cause gray mold on leaves, flowers, and stems, eventually leading to plant collapse.
Deer and rabbits enjoy eating the succulent stems so a repellant should be used, either a spray-on or a granular repellent will work.

How to prevent downy mildew:

The best preventive measures include keeping the leaves dry when watering and providing enough air circulation between plants. If you do find impatiens downy mildew, it’s almost impossible to get rid of, and it is best to remove and dispose of the affected plants. To prevent reinfection, don’t plant new impatiens in the same garden bed. While the new plants may not have the disease (even types bred to be resistant are not completely immune), they could still fall victim if planted where spores still linger in the soil. If you haven’t grown them for a few years or you plan to put them in containers, there is less to worry about. Or, plant New Guinea impatiens instead, which are naturally mildew-resistant.

Downy mildew can devastate impatiens.

Additional Tips

Impatiens are sometimes called “Touch Me Nots” because their seed pods have a unique characteristic: when they mature, they burst open upon touch, sending seeds flying in all directions.
Impatiens can get too much sun, particularly in hot climates. Most impatiens prefer partial shade or filtered sunlight, especially during the hottest part of the day. Too much direct sun can cause the plants to wilt, scorch, or suffer from reduced blooming.
Yellow leaves aren’t always a reason to panic, and can be a normal part of a plant’s life cycle.
New Guinea Impatiens is not known to cause harm to humans or pets.

With their quick growth habit and abundant bloom production, impatiens are great choices for your garden. Use as bedding plants and container fillers, or wherever you want continuous color with minimal effort.
