Sunpatiens are exquisite boxy-like flowers that come in vibrant shades of pinks, reds, purples, and whites.

These lovely flowers grace the landscapes of many and fill gardens and outdoor living areas with their charming presence. 

Did you know that Sunpatiens are part of the impatiens family, and these flowers are referred to as “Touch Me Nots?” The coined term comes from the exploding seed pod on the plant. When touched, the pod quickly pops open releasing seeds.

Often these pods can fly up to a few feet in the air!

What are Sunpatiens?

growing sunpatiens

Sunpatiens are a unique series of impatiens that were specifically developed by Sakata Seed of Japan in 2006. Sakata Seed cross-bred two species of impatiens; the New Guinea impatiens and wild impatiens. The goal was to create a species of impatiens that could withstand full sun and warmer climates. 

The three-season feature of Sunpatiens provides a landscaped garden a lovely dimension of color and greenery. Leaves of differing greens, bronzes, and variegations add as the backdrop as the vibrant blooms appear in late spring lasting to mid-fall.

How to Plant & Propagate Sunpatiens

Propagating Methods for Sunpatiens Cuttings

There are TWO simple methods to propagate a Sunpatien cutting. Use either the soil/media method of the water method. It can take up to a month for roots to develop.

Soil/Media Method

Materials you will need:

  • Sharp/sterile knife
  • Planting container
  • Potting soil/media (you can use either potting soil or soil-free media)

Soil-free media (use a mixture of vermiculite and perlite that is damp; soak in water)

  • Grow light
  1. Place your soil-free media in your container.
  2. Start with a healthy mother Sunpatien plant.
  3. Locate the stem that you will cut. It should be:
    • Healthy
    • Free of any blooms
    • 3-6” long
    • Have at least 3 leaves.
  4. Cut your stem (3-6” down) at a 45-degree angle.
  5. Remove any leaves towards the bottom to allow new root growth.
  6. Gently place the cutting into the potting soil/media in the container. 
  7. Water thoroughly.
  8. Place in a warm area under a grow light. 
  9. Continue to mist as needed daily.
  10. Once roots have developed, you can move to the desired planting site.

Water Method

Materials you will need:

  • Sharp/sterile knife
  • Jar or vase
  • Dow rods to support plant
  • Grow light
  1. Fill your jar/vase with water.
  2. Start with a healthy mother Sunpatien plant.
  3. Locate the stem that you will cut. It should be:
  • Healthy
  • Free of any blooms
  • 3-6” long
  • Have at least 3 leaves.
  1. Cut your stem (3-6” down) at a 45-degree angle.
  2. Remove any leaves towards the bottom to allow new root growth.
  3. Place dow rods over the top of the jar/vase to support the cutting.
  4. Gently position the cutting over the jar/vase, ensuring the end is in the water. 
  5. Place in a warm area under a grow light. 
  6. Monitor the water level to make sure the end of the stem cutting is in the water.
  7. Once roots have developed, you can move to the desired planting site.

Transfer Planting

If you have just purchased Sunpatiens at your local nursery, it’s time to get them transferred into a permanent planter or location in your landscape. It’s quite simple to do this.

To a Container

When transferring to a container or hanging basket, use a good potting soil and a container with holes in the bottom for drainage. Fill your container halfway with potting soil. Gently lift and remove your Sunpatien from the nursery container. Place the Sunpatien in the permanent container and fill with the remaining potting soil. Water thoroughly. 

To a Landscape

To transfer to your landscape, be sure to have your planting site prepared. 

  • Site should not be in an area that floods or retains water.
  • Mix a good flower soil mix into the planting site to have a good mixture of earth and flower soil mix.
  • Space Sunpatiens at least 16” apart from one another.
  • Holes should be about 8” deep and 8” wide.

Gently lift and remove your Sunpatien from the nursery container. Place the Sunpatien in the hole and cover with soil. Water thoroughly. 

Growing From Seeds

There are two methods to growing Sunpatiens from seeds. You can either germinate them indoors or plant the seeds directly into the ground outdoors. 

Whether you choose to germinate indoors or plant directly outdoors, follow the instructions on the seed packet. Directions will be specific for your particular zone. Regardless of where you plant them, be sure the plants will get ample sun.

Caring for Sunpatiens

Ease of Care

Level of MaintenanceLow
Sun RequirementsFull sun to partial shade
Sunpatiens are happy to be in the full sun and do rather well in heat and humidity. Never place them in full shade because they will not thrive.
Water RequirementsMedium
Water your Sunpatiens early in the day to avoid disease. Damp plants and soil attract not only disease but pests as well. The best way to know if your plant needs to be watered is to watch for a slight wilt. Water thoroughly once you see this indicator. If you do this, your Sunpatiens will develop a robust root system. It also promotes an uptake in calcium – constant watering results in a weak plant structure.
Soil PreferenceMoist, well-drained
Potential DiseasesBortrytis cinerea (gray mold)Pythium irregulare
Potential PestsFungus gnatSpider miteThrips

Diseases and Pests of Sunpatiens

Sunpatiens have an amazing resistance to disease and pests. However, there are rare occasions something could slip through as we will cover below.


Botrytis cinerea (gray mold)

Cause: high humidity and decaying plant matter

Conditions: temperatures 64-77 degrees (F)

Botrytis cinerea is first noticeable by dusty white growths that turn gray. This disease is spread through spores released into the air. It feeds on decaying plant tissue.

Pythium irregulare

Cause: Soil that is too wet

Conditions: moist

Pythium irregulare is a soilborne disease that causes blight and root rot. It is spread through movement of contaminated water.


There are three pests that can attack Sunpatiens.

Fungus Gnats:

  • Small flies that lay larvae in the soil and potting mixes.
  • Larvae destroy plant roots causing stunted growth and death.

Spider Mites

  • Oval shaped insects
  • Found on the underside of leaves.
  • Leaves appear to have yellow speckles, will turn brown and fall off.


  • Small, slender insects with hairy wings.
  • Leaves appear to be scarred, distorted, and spotted.
  • Flowers may not bloom if infected.
  • Females lay eggs on leaves. The hatched nymphs feed on both the leaves and flowers destroying them.

Management of Disease and Pests

Cultural Control

  • Avoid watering plants late in the day. Diseases love moist and damp plants and soil.
  • Remove all dead plant matter on the ground and the plant. 
  • Thoroughly clean all garden tools to prevent spreading disease.
  • Space plants apart to allow air circulation.
  • Do not water from overhead, instead, water at the base of the plant.
  • Don’t overwater plants.
  • Do not plant in an area that is prone to retaining water or flooding.

Chemical Control

Use of preventative insecticide, miticides, and fungicides should be applied BEFORE infection happens.
