Silver Plants in the Garden

Silver is not a favored color in the garden, evoking a melancholy tone that brings to mind a doomed starlet in the winter of her reign. But there is also a glamorous beauty in the color silver, alluding to bygone days when classiness was not a mere suggestion but a way of life. 

For those who want to bring back the silver-screen era, they must look to silver foliage – not predictable, washed-out fillers often relegated to the back of commercial borders, but stunning iterations that no garden should be without. 

The best garden plants are those that bridge the seasons with their luminous glow. Once the curtain closes on summer and gardeners hurtle into the chillier months, the silver-leaved beauties you dot around your borders and pots really are the secret to the aesthetic cohesiveness of a space. Reminiscent of that clean, frosty morning light, they help to make a garden feel layered, tone down color compositions, and soothe the eyes. 

 

 1. Senecio 'Angel Wings'

Many silver plants have fuzzy leaves, evolved to survive hot, dry, or windy environments. Among them, Senecio candicans 'Angel Wings' has few equals, catching the gardener’s eye each time. The leaves radiate the brightest silvery white, glowing from within so that even the most overcast days cannot dim their shine. As too much moisture or humidity is anathema to this plant, keep it well drained by growing it in raised garden beds. 

2. Artemisia 'Powis Castle'

Artemisia 'Powis Castle' is recommended in areas with a dearth of greenery – gravel beds, hard edges and mulch. Though many relegate it to an underwhelming dusty mound, there are places in the garden where it acts as great filler, assuaging even the most landlocked gardens. When brushed against, it releases a sharp, aromatic herbal scent. As those in the Artemisia genus can get unruly, prune for shape rather than health with a hori hori knife. 

3. Stachys byzantina (Lamb's Ear)

Few gardeners ever invest in silver, to the detriment of their overall harmony. Stachys byzantina offers a classic, neutral contribution of silver. Falling on the sage green side, it thrives on neglect and can be grown in any average to poor soil with good drainage. Plant alongside alliums and red-hot pokers to placate their fierier hues. 

4. Convolvulus cneorum (Silverbush)

Bindweeds are malignant, noxious invaders, yet still some gardeners indulge in them, preferring them to the overtly hideous weeds armed with an abundance of spikes. Silverbush is an evergreen shrub that preserves the desirable trumpet-shaped blooms without the toxic taproots that sprawl underground. Ditch the destitute patches of scorched grass and wilting flowers with groupings of silverbush, a highly drought-tolerant alternative. Those cultivating a moonlit garden filled with night-blooming flowers often find daylight flowers overly garish, but silverbush is an exception, bridging the hours between twilight and dawn.  

5. Brunnera macrophylla 'Jack Frost'

Many silver-shaded plants appear as if they need a good wash. Their ancestors, adapting to harsh deserts and arid regions, knew that they could not rely on a constant supply of water – it is this deficit that makes them invaluable in drought-tolerant, alpine, and xeric gardens. By contrast, this plant is a shade-tolerant species that grows in moisture-retentive soils. Detailed with a crackle-like finish, it is a unifying force for those that wish to thread cool tones throughout the garden. 

6. Santolina chamaecyparissus (Lavender Cotton)

Lavender cotton may seem like an irritating sidekick, much the same way Guy views his comrade Sam in Green Eggs and Ham, yet just as Sam constantly shows up for Guy, lavender cotton is devoted to being present at the roll call of your garden. It can be clipped into tight, formal mounds or allowed to tumble naturally over dry-stone walls. The fragrance is deeply pungent and clean, and it excels in poor, gritty soils where other plants might falter.

7. Eryngium giganteum 

Many aren’t sure what to make of Eryngium giganteum, colloquially known as Miss Willmott's ghost, but it does make for an interesting garden marker. This is perhaps the same sentiment once accorded to Miss Willmott, a wealthy 19th century horticulturist considered prickly and eccentric by her peers, and thought to have practiced an early form of guerrilla gardening. Those that want their gardens visited by a plant that gives off ghostly vibes, perhaps reminiscent of drowned sailors at sea, can look forward to growing this sea holly. 

8. Festuca glauca 'Elijah Blue'

No list of silver plants would be complete without an ornamental grass, and 'Elijah Blue' is a great companion. Forming neat, spiky pincushions of powder-blue and silver like a sea urchin, this ornamental grass provides a brilliant geometric contrast to softer, leafy neighbors. It maintains its striking coloration throughout the coldest months, ensuring your containers and borders never feel flat or empty.

9. Salvia argentea

Another plant that invites tactile engagement is the plush leaves of silver sage, generously covered in silky white hairs. It looks wonderful in contrast with fine-textured grasses and delicate flowers in cottage gardens. At first glance, it almost appears like a cabbage, but without the coarse, utilitarian appearance. To enhance the cottage garden theme, twine clematis and other lush vining plants over wall trellises. 

10. Lychnis coronaria (Rose Campion)

The vivid magenta flowers of rose campion prove that pink and silver can coexist, earning it a place in the autumn garden. The leaves are soft, felted, and a pale, luminous silver-grey. Long after the blooms have faded, these velvety rosettes remain hugging the ground, providing a bright, clean textural accent that keeps the garden grounded through the quiet months ahead.
