Embrace Sustainability: Drought Resistant Plants That Will Flourish In Alberta's Gardens

Across many regions of Alberta, where the summers can be scorching and rainfall sporadic, gardening can pose a challenge. Now to top that off, at least for the Southern part of the province, a water ban (which has now been reduced to a water restriction), has even further limited our hopes for any success in our dirt patches. 

However, if remain optimistic, wise and make conscientious plant choices, maintaining a vibrant garden can be not only feasible but also rewarding. One of the keys to success lies in selecting drought-resistant plants that thrive in Alberta's climate without excessive water consumption. Let's explore some of the top contenders for your drought-resistant garden oasis.

1. Russian Sage (Perovskia atriplicifolia)

Known for its aromatic silver-grey foliage and delicate lavender-blue flowers, Russian Sage is a standout in xeriscape gardens. Thriving in full sun and well-drained soil, this perennial adds both texture and color to any garden while requiring minimal watering once established.

2. Liatris (Liatris spicata)

A native prairie plant, Liatris boasts tall spikes of purple or white flowers that attract pollinators like butterflies and bees. This hardy perennial is perfect for Alberta's climate, tolerating dry conditions and thriving in full sun. Planting Liatris in clusters can create a striking visual effect while conserving water.

3. Sedum (Sedum spp.)

Sedums are a diverse group of succulents that excel in dry conditions. Their fleshy leaves and low-growing habit make them ideal ground covers or additions to rock gardens. Varieties like Autumn Joy (Sedum spectabile) add seasonal interest with their changing colors, from green in spring to pinkish-red in fall.

4. Yarrow (Achillea millefolium)

Yarrow is a hardy perennial with feathery foliage and flat-topped clusters of flowers in shades of white, yellow, pink, or red. This versatile plant is drought-tolerant once established and thrives in sunny spots with well-drained soil. Yarrow also attracts beneficial insects, making it a valuable addition to any eco-friendly garden.

5. Blanket Flower (Gaillardia spp.)

Gaillardia, or Blanket Flower, is a native wildflower that blooms profusely throughout the summer with daisy-like flowers in vibrant hues of red, yellow, and orange. These cheerful blooms not only add a splash of color but also attract pollinators to your garden. Blanket Flowers are well-suited to Alberta's dry summers and require minimal watering once established.

6. Prairie Smoke (Geum triflorum)

Prairie Smoke is a unique native perennial with bell-shaped pink flowers that turn into feathery seedheads resembling smoke. This low-maintenance plant thrives in dry, sandy soils and is an excellent choice for naturalizing in prairie-style gardens.

Tips for Success:

• Water Wisely: During establishment, water deeply and infrequently to encourage deep root growth. Collect rainwater, recycle your grey water from dishes and showers can all help to supplement your watering needs during a drought or a restriction. 
• Mulch: Use organic mulch to retain moisture and suppress weeds around plants.
• Group Plants by Water Needs: Create microclimates in your garden by grouping plants with similar water requirements together. This not only eliminates the risk of over/underwatering certain species, it will help limit water usage in your garden.
• Native Plants: Consider native species as they are well-adapted to local conditions and support local biodiversity.

By selecting drought-resistant plants like Russian Sage, Liatris, Sedum, Yarrow, Blanket Flower, and Prairie Smoke, gardening enthusiasts in Alberta can create thriving, sustainable gardens that require less water and maintenance.

Embracing these resilient plants not only conserves water but also fosters a more resilient ecosystem in your backyard. With thoughtful planning and a commitment to sustainability, your garden can flourish even in Alberta's challenging climate. Happy gardening!
