Globally, cities are expanding. By 2050, more than two-thirds of the population is expected to live in urban areas. This growth increases the demand for green spaces, prompting people to find creative ways to incorporate nture into a limited footprint. At the same time, awareness of native plants’ importance is on the rise. Driven by this need and curious about the outcomes, I took on the challenge of discovering to what extent native plants can successfully be grown in containers. With a mix of enthusiasm, trial and error, and plenty of sweat, I discovered what works best—often through unexpected lessons along the way.

Gardening in a major city

Annuals are far from the only plants that offer summer color on city balconies. A multitude of native plants create stunning container displays.

As an urban botanist based in Chicago, my encounters with wild plants are often limited to the same aggressive species pushing through sidewalk cracks or the predictable selection of ornamental plants in city gardens. While I appreciate the resilience of dandelions, the summer displays of impatiens, and even the fiery red of burning bushes in the fall, I know native plants can offer so much more. Determined to bring biodiversity to my own urban space, I transformed my small 5×10 balcony into a haven for native Illinois prairie species—an experiment driven by curiosity, a love for plants, and the challenge of growing them in pots year after year. With little guidance available on overwintering natives in containers, I had to select pots that could withstand Chicago’s harsh freeze-thaw cycles, experiment with different soil compositions, and carefully choose species that could thrive in a limited space.

Overwintering Results

Beautiful for the gardener and beneficial for pollinators: These bees flocking to an anise hyssop (Agastache fennelZones 4–8) say this native plant experiment was a success.

Over 15 years, I’ve learned which native plants survive best in pots, which struggle, and which ones flourish beyond expectations. Species with fibrous roots or rhizomes, like certain asters and sedges, tend to overwinter well, while tap-rooted plants often struggle. I’ve also found that “nurse” plants, like Carex species, help stabilize soil and protect more delicate neighbors. Some of my standout performers include nodding onion (Garlic cernuumZones 4–8), partridge pea (Chamaecrista fasciculataZones 3–9), and aromatic aster (Symphyotrichum oblongifoliumZones 3–8), while overachievers like wild columbine (Aquilegia canadensisZones 3–8) and stiff goldenrod (A rigid oligoneuronZones 3–9) are great for beginners.

Overachievers:

I would recommend these plants for first-time growers. All were overall really robust and will thrive even with occasional neglect.

Stiff goldenrod (A rigid oligoneuronZones 3–9)
  • Wild columbine (Aquilegia canadensisZones 3–8)
  • Lanceleaf coreopsis (Coreopsis lanceolateZones 4–9)
  • Stiff goldenrod (A rigid oligoneuronZones 3–9)
  • Giant Solomon’s seal (Polygonatum exchangedZones 3–7)
  • Heath aster (Symphyotrichum ericoidesZones 3–10)
  • New England aster (Symphyotrichum new-englandZones 4–8)

Favorite top performers:

Wild blue phlox
Wild blue phlox (Phlox divaricataZones 3–8)

In total, there are 23 plants that made my top-performers list. Here, I will keep the selection brief and highlight some of my favorites. Let me know in the comments if you’d like a deeper dive on this topic and my full list of recommendations.

  • Partridge pea (Chamaecrista fasciculataZones 3–9) reseeds and attracts wonderful pollinators.
  • Nodding onion (A bunch of garlicZones 4–8) is a reliable performer. The city of Chicago gets its name from the Algonquin Indian name for this plant, chigagouso Chicagoans can have a little extra pride growing this native.
  • Spotted beebalm (Monarda punctureZones 3–8) self-seeds easily and produces a wonderful display. It also attracts some amazing wasps.
  • Sand phlox (Phlox bifidaZones 4–8) and wild blue phlox (P. divaricataZones 3–8) are two of many phloxes that are amazing and worth the effort.
  • Aromatic aster (Symphyotrichum oblongifoliumZones 3–8) is not too aggressive and has amazing fall color.

Favorite good performers:

Harebell
Harebell (Campanula rotundifoliaZones 3–6)

This list is longer—31 native plants altogether. These are all wonderful, but there were small issues that left them off the top-performers list. Either they did not do well every year or were a messier plant to deal with, but that does not mean they aren’t worth buying and potting up. Here were my favorites from that list:

  • Anise hyssop (Agastache fennelZones 4–8) is almost a top performer but is messy and big. However, pollinators love it, and it also self-seeds nicely.
  • Canada anemone (Anemone canadensisZones 3–8) is a bit aggressive but produces a nice display.
  • Harebell (Campanula rotundifoliaZones 3–6) is a little messy but so beautiful.
  • Prairie clover (Dalea spp., Zones 3–8) can create such great displays but does not always overwinter well.
  • Fringed loosestrife (Lysimachia ciliatesZones 3–9) was a surprise. The color and floral display are wonderful, but it can also be aggressive.
  • Starry campion (Silene starryZones 5–8) has fantastic flowers, but it did struggle at times.
  • Large-flowered bellwort (Uvularia grandifloraZones 4–9) is a personal favorite that lived many years but did not always flower.

Conclusion

The moral of this story: You have more gardening options than you might imagine in a small space. Any urban gardener can plant up a plethora of beneficial plants in just a couple of containers.

Despite setbacks, this ongoing experiment has proven that native plants can thrive in containers, providing vital habitat for pollinators and adding beauty to even the smallest urban spaces. My hope is that by sharing my success, more city dwellers will be inspired to bring native plants into their own lives, creating richer, more sustainable urban landscapes.
