Did You Know?
1. The Impatiens genus, commonly known as “Busy Lizzies,” is named after the Latin word “impatiens,” which means “impatient” or “without patience.” This name alludes to the plant’s tendency to scatter its seeds eagerly when touched, leading to its rapid and widespread growth.
2. Impatiens flowers display an intriguing process known as “explosive pollination.” When an insect lands on the flower, its weight triggers a rapid release of stored energy in the form of a spring-like mechanism. This ejects pollen onto the insect, ensuring the efficient transfer of pollen to other flowers.
3. While most impatiens are annual plants, meaning they complete their life cycle in one growing season, there are perennial varieties as well. One such perennial impatiens, known as Impatiens sodenii or the “Poor Man’s Rhododendron,” can live for several years under the right conditions.
4. If you thought impatiens only grew as vibrant flowers, think again! Some species of impatiens are valued for their nutritious leaves, which are used in traditional cuisine across parts of Africa and Southeast Asia. These edible varieties are commonly referred to as “vegetable jewelweeds.”
5. Impatiens are not impervious to pests, and one particular insect that can pose a threat to these plants is the aptly named “impatiens necrotic spot virus.” This virus is transmitted by tiny insects called thrips, which feed on the sap of impatiens plants, causing severe damage and even death if left untreated.

Growing Impatiens In Different Climates
New Guinea impatiens are suitable for cultivation in USDA zones 10-12, as they are native to the tropical region of New Guinea. These plants thrive in high-humidity areas, where temperatures remain relatively warm throughout the year. In these zones, New Guinea impatiens can be grown as perennials, providing years of beauty and enjoyment.
For gardeners residing in other climate zones, New Guinea impatiens can still be cultivated as annuals. To do so, one can purchase established plants and transfer them to the garden. It is crucial to wait until all danger of frost has passed and the night temperatures consistently remain above 45°F before planting the impatiens outdoors.
The amount of sun exposure required for New Guinea impatiens depends on the climate. In hot and sunny regions, it is best to provide them with morning sun and afternoon shade to prevent scorching. This will allow the plants to thrive without suffering from excessive heat stress. In cooler climates, they can tolerate more direct sunlight but may still benefit from some shade during the hottest parts of the day.
Care And Maintenance For New Guinea Impatiens
Proper care and maintenance are essential for ensuring the prolonged beauty and health of New Guinea impatiens. These plants prefer slightly acidic soil and thrive in well-draining soil that retains moisture. It is essential to strike the right balance when watering to promote proper growth. Regular watering is crucial, but overwatering or letting the soil dry out for extended periods can negatively affect the plant’s overall health.
In addition to regular watering, supplemental fertilizer specifically formulated for blooming flowers should be applied every three to four weeks during the growing season. This will provide the necessary nutrients for the plants to develop robust blooms and lush foliage.
To encourage optimal growth and minimize competition for resources, it is crucial to keep weeds under control. Regular weeding and mulching the surrounding soil will help maintain a clean environment for New Guinea impatiens to thrive. Furthermore, these plants can be grown in containers, making them versatile for use in edging or bordering gardens.
Propagation And Pest Control For Impatiens
New Guinea impatiens can be easily propagated from cuttings. To do so, take a stem cutting with a few pairs of leaves and ensure it has nodes present. Place the cutting in a well-draining potting mix and keep it consistently moist until it establishes roots. Once the roots have developed, the cutting can be transplanted into a larger pot or directly into the garden.
When it comes to pest control, common pests that affect impatiens include aphids and spider mites. Regular inspection and use of insecticidal soaps or horticultural oils can help mitigate these issues. Additionally, practicing good garden hygiene by removing dead or damaged plant material can help discourage pest populations.
