Impatiens Walleriana Germination

Impatiens walleriana is an annual flower from African rainforests. In the United States, you find it cultivated indoors, as outdoor potted plants or in the flowerbed. Impatiens develops as a 2 ½-foot-tall mound of pink, white, purple, orange and red flowers depending on the variety. They bloom from early summer through early fall. Although impatiens seeds require some special attention, getting them to germinate is a simple process. Start them indoors 10 to 12 weeks before the last freeze.

Planter with drainage holes
Potting mix
Clear plastic film
Shallow tray
Propagation mat as needed

Instructions

- 1
  Fill a planter with potting mix to within ½ inch of its rim. Select a pot that has drainage holes. Hydrate the soil until excess water flows out of the drainage holes and the surface is evenly moist.
- 2
  Sow impatiens seeds on the soil surface. Keep them exposed, as they require light to germinate. Cover the planter with a piece of clear plastic film to maintain the environment warm and humid.
- 3
  Place the planter in a shallow tray of water for the potting mix to absorb moisture through the drainage holes. Irrigate the seeds in this manner until they germinate to avoid dislodging them. Water the soil whenever the surface begins to dry.
- 4
  Move the planter to an area that stays at 70 to 75 degrees Fahrenheit, impatiens' required range for germination. Set the pot on an electric propagation mat to heat the soil if necessary. Germination occurs in two to three weeks.
