Drought-Tolerant Perennials

As the effects of climate change become increasingly apparent, it is vital for gardeners to embrace drought-tolerant perennials. These hardy plants not only thrive in dry conditions but also offer stunning beauty and low-maintenance care. In this blog post, we will explore some of the most popular drought-tolerant perennials for New Brunswick, discuss their care requirements, and provide guidance on when and where to plant them.

Sedum 'Autumn Joy' (Stonecrop): Sedum 'Autumn Joy' is a beloved choice for New Brunswick gardens due to its resilience and long-lasting appeal. This perennial produces fleshy, succulent leaves and clusters of vibrant pink flowers in late summer and early fall. 'Autumn Joy' thrives in full sun and well-drained soil, making it an excellent option for drought-prone areas. These low-maintenance plants require minimal watering once established and are highly tolerant of New Brunswick's variable climate. 

Lavandula angustifolia (English Lavender): Known for its heavenly fragrance and stunning purple flowers, English Lavender is a classic choice for water-wise gardens in New Brunswick. This perennial thrives in full sun and well-drained soil. It requires regular watering during its establishment phase but becomes more drought-tolerant once mature. English Lavender blooms from early to mid-summer and can be pruned after flowering to maintain its compact shape and encourage vigorous growth.

Echinacea purpurea (Purple Coneflower): With its vibrant purple petals and distinctive cone-shaped center, Purple Coneflower adds a pop of color to any garden. This native North American perennial is well-suited to New Brunswick's climate. It thrives in full sun to partial shade and can tolerate a wide range of soil conditions. Purple Coneflower requires regular watering during its first year but becomes more drought-tolerant as it matures. This long-blooming perennial attracts pollinators and can be divided every few years to rejuvenate the plant.

Coreopsis verticillata (Threadleaf Coreopsis): Threadleaf Coreopsis is a hardy perennial that offers delicate, fern-like foliage and bright yellow flowers. It flourishes in full sun and well-drained soil. Once established, Threadleaf Coreopsis is remarkably drought-tolerant and requires minimal watering. Deadheading spent flowers can promote continuous blooming throughout the summer. This perennial also attracts butterflies and other beneficial insects, making it an excellent addition to any New Brunswick garden.

• Water newly planted perennials deeply and regularly during their establishment phase, typically the first year.
• Once established, reduce watering to allow the plants to develop deep root systems. Water deeply but infrequently to encourage root growth.
• Apply a layer of organic mulch around the base of the plants to help retain moisture and suppress weed growth.
• Avoid over-fertilizing drought-tolerant perennials, as excessive nutrients can promote excessive foliage growth rather than flowering.
• Regularly monitor your plants for signs of stress, such as wilting or yellowing leaves, and adjust watering as needed.

Drought-tolerant perennials can be planted in New Brunswick in early spring or fall when the soil is workable. It is crucial to choose a location that receives ample sunlight, as most of these plants thrive in full sun. Ensure the soil is well-drained, as excessive moisture can be detrimental to drought-tolerant plants. Consider grouping together plants with similar water needs to optimize water usage and create an aesthetically pleasing display
