Wild Calla: A Native Wetland Beauty for Your Water Garden
If you’re looking to add some native charm to a wet spot in your yard, meet the wild calla (Calla palustris) – not to be confused with those fancy florist calla lilies! This delightful native perennial is a true North American treasure that’s been quietly beautifying our wetlands for centuries.
What Makes Wild Calla Special?
Wild calla is a native forb – that’s garden-speak for a non-woody perennial plant that dies back to the ground each winter. Don’t let its humble classification fool you, though. This little beauty packs a visual punch with its glossy, heart-shaped leaves and distinctive white flowers that look like tiny calla lilies (hence the common name callalily).
Where Does Wild Calla Call Home?
This hardy native has an impressive range across North America. You’ll find wild calla thriving from Alaska down through Canada and into the northern United States. It grows naturally in Alberta, British Columbia, Manitoba, New Brunswick, Nova Scotia, Ontario, Prince Edward Island, Quebec, Saskatchewan, Yukon, Northwest Territories, and Nunavut. In the U.S., it’s found in Connecticut, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, North Dakota, Ohio, Pennsylvania, Rhode Island, Vermont, Wisconsin, and even extends into Labrador and Newfoundland.

Growing Wild Calla Successfully
The secret to happy wild calla is simple: keep it wet! Here’s what you need to know:
Growing Conditions:
- Moisture: Wet to saturated soil is essential – think bog conditions
- Light: Partial shade to full sun (more tolerant of sun when soil is consistently wet)
- Soil: Rich, organic, acidic soils work best
- Hardiness: Zones 2-6 (this plant loves the cold!)
Planting and Care Tips
Getting started with wild calla is straightforward if you have the right conditions:
- Location is everything: Choose the wettest spot in your yard or create a bog garden
- Spring planting: Best time to establish new plants
- Spacing: Allow room for natural spreading through underground rhizomes
- Minimal fertilizer: These plants prefer naturally rich, organic soil
- Winter care: None needed – they’re incredibly cold hardy
A Word of Caution
While wild calla is a wonderful native plant, it’s worth noting that all parts of the plant contain calcium oxalate crystals, which can be irritating if ingested. Keep this in mind if you have curious pets or small children.
The Bottom Line
Wild calla is a fantastic choice for gardeners with wet areas who want to embrace native plants. It offers unique beauty, supports local wildlife, and requires minimal care once established. Just remember – this isn’t a plant for dry gardens! If you’ve got a soggy spot that other plants won’t tolerate, wild calla might just be your perfect match.
By choosing native plants like wild calla, you’re not just creating a beautiful garden – you’re supporting the intricate web of life that makes our local ecosystems thrive. And that’s something worth celebrating!
