As our Calgary summers draw to a close, many local gardeners are turning their focus to creating or improving their ponds. Water gardens are a wonderful way to bring tranquility, attract wildlife, and add vibrant colors to your outdoor space—even in our region’s often cool and variable climate. Whether you’re a seasoned pond keeper or just starting out, choosing the right plants can make all the difference in water quality, aesthetic appeal, and habitat diversity.
Plant Recommendations for Your Calgary Water Garden
Water Violet (Hottonia palustris):
An excellent choice for oxygenating your pond and adding delicate pink blooms. It thrives fully submerged up to 12 inches deep, making it perfect for enhancing water clarity and creating a soft, natural look.
Tulbaghia violacea ‘Variegata’:
Ideal as a marginal or container plant, this variegated society garlic adds a splash of grey-green with cream stripes. Its fragrant purple flowers attract pollinators and provide a lovely scent around your pond area.
Scirpus cernuus (Fiber Optic Plant):
A charming, low-growing plant that resembles fiber optic lights with silvery tips. Its clumping habit makes it great for floating planters or baskets, filling in open spaces and adding texture to your water garden.
Carex elata ‘Bowles Golden’:
A hardy ornamental grass with bright yellow-golden foliage. It’s excellent for creating contrast and visual interest along pond edges and is resilient enough to survive Calgary’s cold winters.
Water Hibiscus (Hibiscus moscheutos):
A show-stopping plant with large, vibrant pink blooms that reach 4-5 feet tall. Perfect for adding tropical flair and a dramatic focal point in your pond. It prefers slightly acidic water conditions.
Myriophyllum brasiliensis:
A submerged water plant with striking red stems and fuzzy, feathery foliage. It offers excellent surface coverage, provides shelter for fish, and helps oxygenate the water.
Water Hyacinth (Eichhornia crassipes):
A highly effective floating plant for shade, nutrient absorption, and water clarity. Its rapid growth and dense roots create ideal spawning grounds for fish and help control algae. Be mindful of its pH preferences—lower pH levels (below 7.4-7.6) support its growth.
Colocasia ‘Illustris’:
An eye-catching tropical plant with dark leaves veined in bright green, bringing a Hawaiian vibe to your pond. It prefers slightly acidic conditions and is excellent for container planting or floating islands during the summer.
Mare’s Tail (Hippuris vulgaris):
A reliable, hardy aquatic plant that grows deep in the water, providing filtration and oxygenation. Its miniature Christmas tree shape adds a natural, decorative element to your pond’s landscape.
Tips for Success in Calgary
- Test your pond’s pH regularly: Plants like water hyacinth and imperial taro thrive in slightly acidic water; aim for below 7.4-7.6.
- Diversify your plantings: The more healthy plants you grow, the better your water quality—plants naturally filter, oxygenate, and stabilize your pond ecosystem.
- Manage excess growth responsibly: When plants such as water hyacinth become overgrown, compost the extras rather than discarding them irresponsibly.
- Protect tropical plants during winter: Bring tropical species indoors or into sheltered areas before the first frost to enjoy their beauty year-round.
Final Thoughts
Creating a thriving, clear-water pond in Calgary is entirely achievable with thoughtful plant selection. From the nutrient-absorbing rapid grower, water hyacinth, to hardy options like mare’s tail and the tropical allure of imperial taro, there’s a plant suited for every pond and every gardener’s vision. Remember, a diverse plant palette promotes water clarity, habitat variety, and overall pond health.
So get outside, experiment with new plants, and enjoy the peaceful beauty of your water garden throughout the year. Happy ponding!
