For Height, Drama, and Eye-Catching Interest
By Ava Green
Every well-designed garden needs an anchor, something tall and confident at the back that gives the whole planting a sense of structure and depth. While shrubs and trees often fill that role, perennials can also do the job beautifully. The back row perennials below are sturdy, reliable performers that thrive right here in Norfolk County. Plant them at the back of a border or the centre of an island bed as the backdrop that makes everything around them look better.
False Indigo, Baptisia australis
Baptisia is one of those perennials that gardeners discover and immediately wonder why they waited so long to plant it. In late spring, masses of stems are loaded with sweet pea-shaped flowers in shades of indigo blue, soft yellow, white or purple, and butterflies and bees absolutely love them. Once the blooms fade, the plant takes on a handsome, shrub-like form with blue-green foliage that holds its shape nicely for the rest of the season. While it’s slow to establish, it is extraordinarily long-lived, making it a plant you put in once and enjoy for decades.
Grows 3 ft tall and 3 ft wide | Full sun to partial shade | Blooms late spring to early summer
Hollyhocks, Alcea
Few perennials carry the nostalgic, romantic charm of a Hollyhock in full bloom. Their tall, stately spires are covered in large, papery flowers and are available in an irresistible range of colours from soft pastels to rich burgundies and deep purples, to classic white. They have a way of making a garden feel established in their first season, making them a desirable back-row choice.
Grows 2-8 ft tall and 1-2 ft wide | Prefers full sun but will tolerate part shade | Blooms in summer
Joe Pye Weed, Eutrochium or Eupatorium
A native plant that is as ecologically valuable as it is beautiful. Its large, showy clusters of rosy-purple flowers are a magnet for butterflies and pollinators from mid-summer well into fall, long after many other perennials have finished their show. If you want a back-row plant that works hard for wildlife while adding bold colour to the garden, this is an excellent choice.
Grows 4-6 ft tall and 2-4 ft wide | Prefers part sun and moist soil | Blooms mid-summer to late fall
Russian Sage, Perovskia atriplicifolia or Salvia yangii
When the garden fills up with yellow and orange blooms in late summer, Russian Sage arrives with a billowy, airy cloud of lavender-blue flower spikes rising above silvery-grey foliage. It catches the light beautifully and adds a softness that few other plants can match. Drought-tolerant once established and virtually pest-free, it is one of the lowest-maintenance perennials you can grow. Compact varieties are also available if space is limited.
Grows 3-4 ft tall and 3-4 ft wide | Full sun | Blooms mid-summer to fall
Bear’s Breeches, Acanthus Mollis
If you’re looking for a plant that makes a genuine architectural statement, Bear’s Breeches is in a category of its own. Its large, deeply lobed, glossy foliage forms an impressive mound, while dramatic flower spikes shoot three to five feet upward, bearing creamy white snapdragon-like blooms accented with striking reddish-purple bracts. It is bold, sculptural, and unlike almost anything else in the garden.
Grows 3-5 ft tall and 2-3 ft wide | Full sun to part shade | Blooms June to July
Foxglove, Digitalis
There is something undeniably enchanting and regal about Foxglove with its tall spires of tubular flowers freckled and spotted on the inside, nodding gently in the breeze. The colour range is also wonderful, from soft creamy whites and pale pinks to rich purples and deep rose. Many varieties self-seed freely, naturalizing happily in the garden over time. One important note: every part of the Foxglove plant is toxic to people and pets, so it is best planted away from areas where children or animals play. In the right spot, however, it is one of the most beautiful back-of-the-border plants available.
Grows 2-5 ft tall and 2 ft wide | Sun to part shade | Blooms in summer
Goat’s Beard, Aruncus diocus
Despite its stature, this is one of the most graceful and softening plants you can add to a shady border. Large, feathery plumes of creamy white flowers rise above finely divided, elegant foliage, bringing lightness to even the darkest corners of the garden. It is especially effective at softening hard edges, filling bare spots under trees, and providing a lush, natural backdrop for smaller shade-loving plants. Dwarf varieties are available for smaller spaces.
Grows 6 inches (dwarf) to 6 ft tall and 2-4 ft wide | Partial to full shade | Blooms early to mid-summer
Gardener’s Tip:
Removing spent blooms before they go to seed, also known as deadheading, encourages many perennials to produce a second flush of flowers later in the season. It takes only a few minutes and can extend your bloom display by weeks.
Ready to Build Your Back Row?
The team at Eising Garden Centre is here to help you choose the right tall perennials for your space, your soil, and your sun conditions. Stop by and let us help you create a border that looks stunning from front to back, season after season.
A well-chosen hedge can do a lot more than just look great—it can give you privacy, act as a windbreak, define garden spaces, reduce noise, or add year-round greenery. Whether you're looking to block out a view, frame your garden, or just create a lush backdrop, hedges are incredibly versatile.
One of the most underappreciated roles of a hedge? It makes everything in front of it—flowers, trees, garden art—look even better. Think of it as a green stage curtain that lets your garden stars shine.
Pretty much any shrub planted in a row can create a hedge, but the right plant depends on what you want it to do. Here are some of our top picks.
Evergreen Hedges - The Classic Green Wall
Botanical Name: Thuja occidentalis 'Smaragd'
Cedar is a favourite for a reason. With its dense, year-round green foliage and low-maintenance nature, it's ideal for privacy. Depending on the type, cedars can grow between 9–14 feet tall, forming a living wall that blocks wind, noise, and prying eyes. It also makes a lovely backdrop for all your other plants.
Botanical Name: Ilex glabra
Looking for a Boxwood alternative? Inkberry Holly is a great choice—especially if you're concerned about Boxwood Blight. This broadleaf evergreen keeps its dark, glossy green leaves all year and can grow up to 8 feet tall if left unpruned. It loves full sun, wet soil, and even acidic conditions. You can trim it to keep it neat or let it grow naturally—either way, it makes a fantastic border or garden divider.
Botanical Name: Taxus cuspidata
With dense, dark green foliage that stays lush all year-round, Yews make excellent hedges for privacy, property lines, and garden backdrops. They’re incredibly versatile—leave them to grow naturally for a softer look or trim regularly for a crisp, formal shape. Yews respond beautifully to pruning, creating a smooth, tailored finish. Just be sure to wear gloves when handling them, and plant them away from children, pets and livestock, as all parts of this striking plant are toxic.
Deciduous Hedges with Drama and Colour
Botanical Name: Spiraea x vanhouttei
Graceful, arching branches that are completely covered in double-white blooms in the Spring make Bridalwreath Spirea a truly stunning hedge plant in the spring. After its spring show, small, glossy green leaves cover this plant until the fall, when its leaves take on beautiful autumn colours.
Bridalwreath Spirea grows to a mature height of 4-9 feet, can tolerate light shade as well as a variety of soil conditions and can be lightly pruned to shape. They are also deer-resistant.
Botanical Name: Cotoneaster lucidus
Peking Cotoneaster may not be flashy, but there are lots of reasons to love this shrub. Its smooth, dark green leaves create a clean, structured look that works beautifully behind flowering plants or along fences. In fall, the leaves turn a fiery red, and black berries appear, which birds snack on through the winter. Growing 5–7 feet tall, this shrub is also a great choice for wind protection and bird habitat.
