When they’re at their best, Impatiens grow into these beautiful, densely branched mounds that look like sturdy little shrubs from a distance. But don’t let that “tough bush” look fool you! These plants are actually quite delicate and absolutely terrified of the frost.
Planting Your Impatiens
That bushy shape is a real lifesaver in garden design all summer long. Since Impatiens usually stay pretty low—topping out around 12 inches—they are perfect as ground cover, colorful border edging, or tucked under taller plants. They also look stunning in containers; a pot at least 6 inches in diameter is usually enough to let this “shrub” really shine. Whether you keep them on the balcony or as a houseplant on a sunny windowsill, they’re sure to impress.
You can get a head start by sowing seeds indoors in March, or just grab some starts from your local nursery in mid-May. Use a nutrient-rich, well-draining potting soil and don’t forget a drainage layer at the bottom. If you’re planting them directly in a flower bed, mix in some compost for nutrients and a bit of sand to keep the soil nice and airy.
The Perfect Summer Spot
The Impatiens family is a big one. While there are some wild varieties we try to get rid of, the garden types are total keepers. They all love light, but they aren’t big fans of the harsh, direct midday sun. You really can’t go wrong with a partially shaded bed. A little morning or evening sun is totally fine, but make sure the location is protected from heavy wind and rain. A roof overhang, a nearby wall, or a larger “bodyguard” plant close by will help keep them safe.
Pro Tip:
Busy Lizzies are super flexible—they’re happy in a shady spot as long as it’s bright enough. That said, there are some newer cultivars specifically bred to thrive in full sun, so check your tags!
Saving Them for Winter
While your Impatiens might look invincible during the summer, their “Achilles’ heel” shows up as soon as autumn hits: they hate the cold. If the temperature drops below 50°F (10°C), these plants are toast. If you want to keep your “bush” alive for next year, you’ve got to take action:
- Dig up garden plants and move them into pots.
- Bring them indoors to overwinter safely.
- Keep them between 50°F and 68°F (10°C–20°C), depending on the variety.
- Make sure they stay in a bright spot away from direct sunlight.
- Keep up with your regular watering and care routine.
