What is the difference between impatiens and New Guinea impatiens?

Impatiens and New Guinea impatiens are both popular choices for adding color to a garden or landscape. While they are similar in some ways, there are a few key differences that set them apart.

1. Sun Tolerance: One of the primary advantages of New Guinea impatiens is their ability to tolerate more sun than regular impatiens. Regular impatiens thrive in shady or partially shaded areas, but New Guinea impatiens can handle more direct sunlight. This makes them a great choice for gardens or landscapes with more sun exposure.

2. Bloom Size and Color Variety: Another noticeable difference is in the size and variety of blooms. New Guinea impatiens typically have larger blooms than regular impatiens. These blooms can range in size from medium to large, creating a more eye-catching display. Additionally, New Guinea impatiens come in a wider variety of colors, including vibrant shades of pink, purple, orange, red, and white. This allows for more options when designing a colorful garden or landscape.

3. Sun Tolerance in Hybrids: While regular impatiens are more shade-tolerant, there are some New Guinea impatiens hybrids that have been bred to withstand full sun. These hybrids have been developed to combine the best traits of regular impatiens and New Guinea impatiens, offering the larger blooms and vibrant colors of New Guinea impatiens while also being able to handle more sun exposure. This makes them a versatile choice for various lighting conditions.

4. Plant Size and Growth Habit: In terms of plant size, New Guinea impatiens tend to be a bit larger than regular impatiens. They can grow up to 12-24 inches tall and wide, whereas regular impatiens typically reach about 8-12 inches in height. The growth habit of New Guinea impatiens is also more upright and bushy, while regular impatiens tend to have a more spreading habit.

5. Watering Needs: Both impatiens and New Guinea impatiens have similar watering needs. They prefer consistently moist soil but can be sensitive to overwatering. It is important to monitor soil moisture and water accordingly to avoid root rot or other water-related issues.

The primary differences between impatiens and New Guinea impatiens lie in their sun tolerance, bloom size and color variety, plant size and growth habit, and the availability of hybrids that can withstand full sun. Considering these factors can help gardeners and landscapers choose the best option for their specific lighting conditions and design preferences.
