Did You Know?
1. Did you know that impatiens are native to the rainforests of eastern Africa, where they thrive in the shade of the forest canopy? They have adapted to low-light conditions and prefer dappled or filtered sunlight rather than direct sun.
2. Impatiens are also known as “touch-me-not” plants because their seed pods explode when touched, dispersing their seeds up to several feet away. This explosive opening of the seed pods is nature’s way of ensuring wider seed distribution.
3. In Southeast Asia, impatiens flowers are commonly used in traditional medicine. The juice extracted from their leaves is believed to have antimicrobial properties and is often used to treat burns, cuts, and skin irritations.
4. Impatiens flowers vary widely in color, from vibrant pinks, reds, and purples to soft pastel shades. However, did you know that impatiens flowers can change colors throughout the day? They tend to be more vivid in the morning and fade slightly as the day progresses.
5. While impatiens are generally known for their season-long bloom in gardens, they also make striking indoor plants. With proper care, they can brighten up a room year-round, adding a pop of color to your home while providing a reminder of the beauty of nature.
Impatiens Sun And Shade Requirements
Impatiens, commonly known as busy Lizzies, are popular flowering plants that brighten up gardens with their vibrant colors. They perform best in partial shade, but can also tolerate heavy shade. However, in heavy shade, they will grow taller and bloom less profusely.
Partial shade refers to areas that receive filtered sunlight or dappled shade throughout the day, such as under trees or near buildings.
It’s important to note that impatiens are not sun-loving plants. Direct sunlight can be too harsh for them, especially during the hottest part of the day. Therefore, it’s ideal to plant them in areas with dappled shade or morning sun and afternoon shade. This allows them to absorb the gentle morning sunlight while being protected from the intense midday rays.
However, it’s worth mentioning that not all impatiens have the same sun and shade requirements. New Guinea impatiens, for example, prefer locations with morning sun and afternoon shade. They are relatively more tolerant of direct sunlight compared to other impatiens varieties, but still thrive best in some shade.
To ensure your impatiens receive the optimal amount of sunlight and shade for growth and blooming, it’s best to observe their reaction to different lighting conditions in your garden. Adjust their placement accordingly for their ideal sun and shade conditions.
Bullet Points:
- Impatiens prefer partial shade and can tolerate heavy shade.
- Plant impatiens in areas with dappled shade or morning sun and afternoon shade.
- Direct sunlight can be too harsh for impatiens, especially during the hottest part of the day.
- New Guinea impatiens perform best in locations with morning sun and afternoon shade.
- Observe impatiens’ reaction to different lighting conditions in your garden and adjust their placement accordingly.
Planting Impatiens Outdoors
Before planting impatiens outdoors, it’s crucial to wait until the danger of frost has passed. Impatiens are highly susceptible to cold temperatures, and even a light frost can damage or kill them. In most regions, it’s safe to plant impatiens after the last spring frost date.
When choosing a planting location, keep in mind the sun and shade requirements mentioned earlier. Select an area that provides the appropriate lighting conditions for the specific impatiens variety you’re growing. Ensure the soil is well-drained and amended with organic matter to promote healthy root development.
If starting impatiens from seeds indoors, they should be sown around 8-10 weeks before the last spring frost. Once the seedlings have developed a few true leaves, they can be transplanted into the garden. Take care not to disturb the fragile roots during transplantation, and give them adequate spacing to prevent overcrowding as they mature.
When planting impatiens, dig a hole that is slightly larger than the root ball and gently loosen the root system before placing the plant in the hole. Backfill the hole with soil, ensuring the top of the root ball is level with the soil surface. Water the newly planted impatiens thoroughly to settle the soil around the roots.

Watering And Fertilizing Impatiens
Impatiens have moderate water requirements and should be watered once a week in garden beds. However, container-grown impatiens may need more frequent watering due to their limited soil volume. Check the moisture level of the soil regularly and water whenever the top inch feels dry. Avoid overwatering, as impatiens do not like wet conditions and can suffer from root rot.
In addition to proper watering, impatiens require moderate fertilization to support healthy growth and abundant blooms. For container plants, a water-soluble fertilizer can be applied every two weeks during the growing season. Choose a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium to provide essential nutrients.
In flower beds, slow-release fertilizers are recommended. These fertilizers gradually release nutrients over time, ensuring a steady supply for the impatiens. Follow the manufacturer’s instructions for application rates and timing.
Regularly inspect the plants for any signs of nutrient deficiency, such as yellowing leaves or stunted growth. Adjust the fertilizer application accordingly to maintain optimal plant health.
Growing New Guinea Impatiens
New Guinea impatiens have slightly different growing requirements compared to other impatiens varieties. They perform best in locations with morning sun and afternoon shade. This allows them to benefit from some direct sunlight while avoiding the intense midday rays.
In terms of soil conditions, New Guinea impatiens prefer moist, well-drained soils. They do not tolerate wet or dry conditions well, so it’s important to find a balance. Adequate drainage is crucial to prevent waterlogged roots, while regular watering is needed to keep the soil consistently moist.
Similar to other impatiens, New Guinea impatiens should be planted outdoors around 2 weeks after the last spring frost. Follow the planting guidelines mentioned earlier to ensure successful establishment.
- Prefer morning sun and afternoon shade for optimal growth.
- Moist, well-drained soils are ideal.
- Avoid wet or dry conditions to maintain health.
- Plant outdoors 2 weeks after the last spring frost.
Remember to provide the ideal conditions for New Guinea impatiens to thrive.
Managing Impatiens Downy Mildew
Impatiens Downy Mildew is a serious disease caused by the water mold Plasmopara obducens. It primarily affects varieties of Impatiens walleriana and Impatiens balsamina, leading to leaf drop, stunted growth, and eventual death of the plants. New Guinea impatiens, however, are more tolerant to this disease.
To manage Impatiens Downy Mildew, sanitation is key. Remove and destroy any infected plants immediately to prevent the spread of the disease. Avoid placing infected material in home compost piles, as the spores can survive and reinfect future plantings.
To prevent the disease from taking hold in your garden, it’s recommended to avoid planting susceptible varieties of impatiens altogether. Instead, choose resistant varieties or explore shade-tolerant alternatives like begonias, pansies, lobelia, torenia, caladium, and coleus.
“By implementing these precautionary measures and staying vigilant, you can minimize the risk of Impatiens Downy Mildew and enjoy healthy, vibrant impatiens in your garden.”
