New Guinea impatiens (Impatiens hawkeri) are vibrant and showy flowering plants that thrive in sunny garden locations. Here’s how to grow and care for them:

1. Light:

   • New Guinea impatiens prefer morning sun and afternoon shade in gardens with eastern exposure.
   • In extremely bright conditions, they’ll need more water and may not bloom as profusely.

2. Soil:

   • These impatiens thrive in slightly acidic soil with a pH range of 6.0 to 6.5.
   • Ensure the soil is moist but well-drained.

3. Starting from Seed:

   • Growing New Guinea impatiens from seed requires patience.
   • Start seeds indoors about three months before your average last frost date.
   • Fill a tray or 6-pack cells with a seed starting mix and water the soil.
   • Plant two seeds in each cell or broadcast them over the tray, covering with a light layer of soil.
   • Germination takes approximately 15 to 20 days.

4. Transplanting:

   • Once seedlings have two leaves, transplant them to the garden or containers.
   • Place them in a bright spot with morning sun and afternoon shade.
   • Keep the soil consistently moist.

5. Maintenance:

   • Weed your garden to eliminate competition for water.
   • New Guinea impatiens can also be grown as perennials in certain zones or as houseplants (though they won’t flower year-round indoors).

Toxicity

New Guinea impatiens (Impatiens hawkeri) are not toxic to humans. In fact, their flowers are edible and are sometimes used in salads. However, it’s essential to note that the plant contains a toxic sap that can be harmful to other plants and animals. So while they’re safe for us, it’s best to handle them with care and keep them away from pets and other sensitive plants.
