During the dog days of summer, having a resilient, dependable, and beautiful perennial flower in your garden is terrific. Meet the Black-Eyed Susan. They are quick to establish and mature, and perfect for a perennial border, cutting garden, or naturalized garden. Depending on the variety, they will grow 1-3 feet tall and spread about 2 feet wide, making them a show-stopping spectacle!

If that and the cheerful, dark-centred, golden-yellow, daisy-shaped flowers aren’t enough to draw you in, here are more reasons we love these plants!

Long Blooming

Black-Eyed Susan (Latin name: Rudbeckia) is a prolific bloomer whose flowers can last from July to October. At a time in the season when many other flowers can look weary, Rudbeckia is a shining star. Its flowers grow on sturdy stems, which adds to their resilience.

Easy to Grow

Rudbeckia are robust! They are drought—and heat-tolerant and generally do well in hard-to-grow locations. Once established, they do not require frequent watering. Rudbeckia hirta is an Ontario native plant, and exceptionally hardy.

Plant Black-Eyed Susan in full sun to partial shade and almost any type of soil. They are adaptable, generally trouble-free and do not require any extra care.

Pollinator-friendly

We aren’t the only ones who love Rudbeckia; butterflies, birds and bees do, too. This makes Black-Eyed Susan a perfect partner for other pollinator-friendly plants like Monarda (aka Wild Bergamot and Bee Balm), Gaillardia (Blanket flower), Yarrow and Echinacea (aka Coneflower).

Who doesn’t love Black-Eyed Susans? Because of the course hairs on the stems, this is a plant that rabbits and deer don’t care for.

Black-Eyed Susan is perfect to grow in a border, bed, planter, or in a field as a mass planting. It’s resilient, attractive, low maintenance and a beneficial addition to any garden!

The much-loved boxwood hedge has been a classic for centuries and is widely used in gardens worldwide. Neatly trimmed and manicured boxwood becomes the framework for containing everything from roses to riots of perennial blooms. From extensive estate gardens to small and modest yards, boxwood is a versatile shrub that earned its place by being easy to care for and prune.

Unfortunately, this staple shrub has trouble brewing, which impacts its leafy lifespan. 

Since its first appearance in Ontario in 2014, the Boxwood Blight has become a significant concern for gardeners. However, the University of Guelph is not sitting idly by. They are actively researching this issue and working hard to find solutions to protect beloved boxwood shrubs.

Sometimes, being popular isn’t all it’s cracked up to be. Because Boxwood is a widely planted favourite, a new pest attracted to it, the Boxwood Moth (from Asia), has easily spread and is infecting shrubs.

Beautiful Boxwood Alternatives

Boxwood Blight and Boxwood Moth do pose severe threats to Boxwood shrubs, but here's the good news—many shrubs make great alternatives! Using a similar shrub is one of the simplest solutions to Boxwood's issues. You have lots of options to protect and diversify your garden.

Inkberry Holly

The closest Boxwood lookalike is the Inkberry holly. It naturally grows in a rounded evergreen mound, can be trimmed like a traditional boxwood hedge, and has other enticing bonuses! Not only is it native to North America, but unlike boxwood, it blooms. In the spring, Inkberry holly is covered in showy white flowers, making it a standout alternative to boxwood. Here at Eising Greenhouses, look for Gem Box Inkberry Holly.

Upright Junipers

Blue Arrow and Moffat Blue Junipers make beautiful hedges and stand-alone accent trees. Both have an elegant upright form, striking blue evergreen foliage, and silvery blue berries from late spring to late fall. If that isn’t enticing enough, add drought tolerance to the list of features!

Showy Shapes and Standards

Consider a standard evergreen or a dwarf variety that has been pruned and sculpted to become a piece of art if you want to add something even more unusual. What’s a standard? It’s usually a single trunk with a plant at the top, like a compact evergreen shrub. 

Standards and shaped dwarf evergreens can make a bold statement or add wonderful whimsy to your garden. We have lots to choose from, but here are a few examples to get your imagination going!

When it comes to replacing boxwood, there are many creative solutions and beautiful plants to choose from!
