This colorful, heat-loving annual brings a tropical flair to your containers or flowerbeds.<\/p>

New Guinea impatiens are a tropical plant hailing from, you guessed it, New Guinea, arriving in the U.S. in 1970. These annuals feature succulent stems and attractive foliage that create the perfect backdrop for large, colorful blooms. There are many foliage variations of New Guineas, ranging from variegated to green with bronze or purple accents.<\/p>

\u00a0<\/div>

The flowers of New Guinea impatiens (Impatiens hawkeri)\u00a0<\/em>are like an exaggerated version of standard impatiens flowers. The showy blossoms are composed of five slightly overlapping petals, arranged around a small, button-like center. They come in a variety of bold hues from pink and white to lavender and orange. Impatiens also have a flower spur full of nectar, which makes them a favorite amongst\u00a0pollinators like moths and butterflies.<\/p>

Where to Plant New Guinea Impatiens<\/span><\/h2>

New Guinea impatiens thrive in part shade with consistently moist,\u00a0well-drained soil. However, they can also withstand full sun or shade, though the plants may yield fewer flowers in these spots. Consider adding organic material, such as compost or manure, to the soil to optimize growing conditions. A slightly acidic pH is ideal. If daytime temperatures are high, seek a spot with protection from the wind, since excessive air flow can dry out the water-loving plants.<\/p>

\u00a0<\/div>

New Guinea impatiens work well in containers or hanging baskets. They can also be grouped in flowerbeds or planted as borders near pools, walkways, or patios. Since they aren’t spreaders, they won’t take up a lot of space in a garden bed and\u00a0mix well with other shade plants. Consider pairing them with plants that don’t bloom as much\u2014the impatiens will more than compensate for any shortage of color.<\/p>

\u00a0<\/div>
\u00a0<\/div>

How and When to Plant New Guinea Impatiens<\/span><\/h2>

Late spring is the best time for planting New Guinea impatiens outside. Find out when your\u00a0last spring frost\u00a0is expected and plan to do your planting two weeks later.<\/p>

\u00a0<\/div>

When placing these annuals in flowerbeds, separate them by the same distance as the expected diameter of the mature plants. (Vigorous varieties may require a little extra room.) Dig a hole about double the size of the root ball.\u00a0Amend the soil with compost\u00a0and add a slow-release fertilizer at the time of planting.<\/p>

\u00a0<\/div>

Avoid planting your New Guineas during the hottest hours of the day, and make sure to give them a thorough soaking immediately after placing them in the ground. Add a layer of mulch around the plants to reduce water loss during peak summer months.<\/p>

\u00a0<\/div>

New Guinea Impatiens Care Tips<\/span><\/h2>

New Guinea impatiens are sensitive to their surroundings: They’re particular about nutrient levels in the soil, and they require lots of water. But the payoff is huge: With the right care, these plants will yield a gorgeous display of tropical flowers.<\/p>

\u00a0<\/div>

Light<\/span><\/h3>

Spots with part shade\u20142 to 6 hours of sunlight per day\u2014are where New Guinea impatiens will thrive. They perform particularly well with the combination of\u00a0morning sun, afternoon shade, and eastern exposure. However, these tropical beauties can also tolerate shade and full sun (especially where daytime temperatures are moderate).<\/p>

\u00a0<\/div>

Note that lots of sunshine, especially when paired with heat, will increase their water requirements, may damage the leaves, and can reduce the size and number of blossoms.<\/p>

\u00a0<\/div>

Soil and Water<\/span><\/h3>

Seek moist but well-drained soil for your New Guinea impatiens, and enrich the earth with\u00a0organic matter like compost. A slightly acidic pH is preferable. Soil that drains quickly reduces the likelihood of root rot.<\/p>

\u00a0<\/div>

Expect your New Guinea impatiens to need lots of water. Their leaves easily lose moisture, and this tendency is exacerbated in low-humidity conditions. They are not drought-tolerant and will often wilt when it’s hot outside if they don’t receive plenty of water. If they start to wilt,\u00a0give them a thorough watering\u00a0and they should bounce back in a few hours. However, the re-hydrated plant may still show signs of stress, including a reduction in blossoms and burnt foliage, especially if wilting occurs repeatedly.<\/p>

\u00a0<\/div>

Try not to let the plants dry out between waterings. (Hint: Plant New Guinea impatiens alongside\u00a0other plants with similar growing requirements.) For established plants, a weekly soaking should be sufficient; newly planted New Guinea impatiens need more water than mature plants.<\/p>

\u00a0<\/div>

Overwatering can lead to root rot, so don’t let the soil become soggy. To help prevent fungal disease, aim the water at the base of the plant, avoiding the foliage and flowers, and cut back on watering when the temperatures are cooler.<\/p>

\u00a0<\/div>

Temperature and Humidity<\/span><\/h3>

Since New Guinea impatiens don’t respond well to cool nighttime temperatures (below 45\u2109), it’s best to plant them about 2 weeks after the last spring frost. The sweet spot for growing them is when daytime temperatures hover between 70 and 85\u2109 and nighttime temperatures fall between 55 and 65\u2109. They will stop producing new buds when nighttime temps are 70\u2109 and higher. New Guineas perform well in high humidity, which reduces water loss through the leaves.<\/p>

\u00a0<\/div>

Fertilizer<\/span><\/h3>

New Guinea impatiens don’t require heavy fertilizing. When you plant them in a flowerbed, simply add a slow-release fertilizer to the soil, and you shouldn’t need to fertilize again. Container garden plants will benefit from a\u00a0biweekly application of water-soluble fertilizer.<\/p>

\u00a0<\/div>

Pruning<\/span><\/h3>

While the plant is immature, pinching the tips of branches can help direct growth into a more attractive shape.\u00a0Leggy impatiens can also be trimmed back\u00a0to a leaf node, though you shouldn’t remove more than 6 inches at a time.<\/p>

\u00a0<\/div>

Although New Guinea impatiens naturally drop their flowers,\u00a0deadheading throughout the season\u00a0will encourage blooming into the fall. This clean-up will also help you avoid the growth of Botrytis fungal mold, which can form on the dead flowers. When removing spent blossoms, simply pinch the stem back, right above the first leaf pair. If your impatiens are potted, shaking the container may also encourage old blossoms to fall off.<\/p>

\u00a0<\/div>

Potting and Repotting New Guinea Impatiens<\/span><\/h3>

New Guinea impatiens make great container plants for patios or even indoors. As a general rule, the pot should be about 1.5 times larger than the diameter of the plant, although there are certain fast-growing varieties that may need bigger containers. Make sure the\u00a0pot allows adequate drainage\u00a0of the soil, and use potting soil, not garden soil.<\/p>

\u00a0<\/div>

Pests and Problems<\/span><\/h2>

Fortunately, New Guinea impatiens are resistant to downy mildew, which can quickly wipe out other impatiens varieties. Common garden pests, like\u00a0aphids, thrips, caterpillars, and spider mites, may invade New Guineas, though they’re typically pest-free.<\/p>

\u00a0<\/div>

While these tropical plants require lots of water, they’re also susceptible to fungal root rot. This may occur in poorly drained soil or in containers that lack a hole for drainage.<\/p>

\u00a0<\/div>

How to Propagate New Guinea Impatiens<\/span><\/h2>

Most varieties are\u00a0propagated by stem cuttings. Cut 2 to 3 inches from the tip of a healthy-looking stem, disinfecting your garden shears with alcohol beforehand. Remove all of the leaves except for the top two. Stick the cutting into moist potting soil, and apply heat to the bottom of the pot if possible with a waterproof heat mat designed for plants.<\/p>

\u00a0<\/div>

As hybrids, most types of New Guinea impatiens are sterile and cannot be grown from seed. A few types, such as the Java and Divine series, may be propagated this way, but often with difficulty. And if the cultivars are patented,\u00a0propagating them may be illegal.<\/p>

\u00a0<\/div>

If you want to start your New Guineas\u00a0from seed, plant them indoors\u00a0about 10 to 12 weeks before you plan to move them outside (roughly 2 weeks after the last spring frost). Fill a starter tray with seed-starting mix, then place two seeds into each compartment. Only lightly cover the seeds with soil, since New Guineas require light to germinate. After misting the seeds, cover the tray with plastic. Place it in a bright spot, keep the soil moist, and take off the plastic once seedlings have two leaves. Let the new plants grow indoors until conditions are warm enough to move them outside.<\/p>
