It’s no secret why the Busy Lizzie (or Impatiens) is a total superstar among home gardeners! These bushy, fast-growing beauties treat us to a spectacular show of blooms from May all the way through October. Whether you’re brightening up a windowsill, a balcony, or a garden bed, here’s everything you need to know to keep them happy and thriving.

Location, Location: Think Shelter and Partial Shade

Your Impatiens will be happiest in a spot with partial shade. You’ll want to avoid harsh, direct midday sun if possible. If you can’t avoid a sunny spot, just make sure the soil doesn’t dry out completely. Also, try to pick a place that’s protected from the wind so those delicate stems don’t snap.

The Secret to Great Growth? Nutrient-Rich Soil

The right foundation makes all the difference. If you’re planting your Busy Lizzies in containers, here’s a pro tip: they actually prefer a slightly snug pot. This encourages the plant to bloom even more vibrantly!
For the perfect soil mix, look for these qualities:

  • It should be loose and well-draining. These plants absolutely hate “wet feet” (standing water).
  • A sandy-loam consistency is the “Goldilocks” zone for them.
  • Make sure it’s rich in organic matter and nutrients.

Best Garden Buddies for Impatiens

Busy Lizzies look absolutely stunning when paired with these plant partners:

  • Fuchsias
  • Petunias
  • Coral Bells (Heuchera)
  • Begonias
  • Fountain Grass

When to Get Digging

These plants are very sensitive to frost, so don’t rush them outside! Wait until mid-May once the threat of frost has totally passed.
When planting, give them some breathing room—about 8 inches (20 cm) apart. Mixing a little compost into the soil during planting is a great way to give them a head start!

How to Grow More (Propagation)

If you want to propagate your collection, you’ve got two easy options: cuttings or seeds.

Growing from Cuttings

In the fall, take some tip cuttings from your healthy plants. Strip off the lower leaves and pop them into small starter pots with moist soil. They usually take root in about three weeks.

Growing from Seed

You’ll know the seeds are ready to harvest when the seed pods turn a translucent, light green. Collect them and start your seeds indoors between January and March. They like a room temperature of around 65°F (18°C). Important note: Impatiens seeds need light to germinate, so don’t bury them deep! You can move your young plants outdoors in early May.

One Last Pro Tip

Impatiens flowers are a bit delicate when it comes to heavy rain—it can make the blooms look a little soggy. If you can, place them under a bit of an overhang or a sheltered spot to keep them looking picture-perfect.
