50 Shades of Grey at Sophie’s Patch
I love shades of grey at Sophie’s Patch, not the movies, but the plants. Grey (or silver) foliage not only looks great and makes a great contrast with all flower colours and other plants, it indicates a hardy plant, able to withstand the onslaught of our tough summers. Grey, silver and white foliage plants have adapted and evolved to cope with extreme conditions of heat and drought, with the silver colour reflecting sunlight so the leaf does not get as hot. Many grey foliage plants are also hairy and these hairs act as an insulation layer for the leaf, like a windbreak, reducing water loss from the leaf. Most grey foliaged plants are sun lovers, thrive in full sun, and once established grow with minimal or no supplementary watering.
So, here is a list of some of the grey (or silver) foliaged plants grown here at Sophie’s Patch. I have ordered them in height, down from trees, tall and medium shrubs, dwarf shrubs, perennials and groundcovers, and then added in a few annuals at the end.
1. Elaeagnus angustifolia – Russian olive
This stunning deciduous tree has bright silver foliage which hangs gracefully off its branches. It produces an insignificant small lemon coloured flower in spring with a delicious sweet scent.

One of many wormwoods we grow, with soft downy silvery white foliage.
26. Artemesia absinthum ‘Lambrook Silver’
This perennial wormwood has fine ferny silvery foliage and is lower growing than the parent, reaching 40-50cm.
27. Artemesia ludoviciana ‘Valerie Finnis’
This hardy plant is one of the best silver foliaged perennials, spreading by underground rhizomes to form a dense thicket of large, jagged silver foliage to 30cm high. Like most Artemesias, its flowers are insignificant and are often removed so that they do not detract from its beautiful foliage.
28. Ballotta pseudodictamnus ‘Nanus’
This is a dense sub-shrub makes a rounded evergreen plant with dense silver-grey foliage, heavily felted with hairs. Although it does produce mauve flowers in spring, they are rather insignificant, and the plant is grown primarily for its foliage. 50cm.
29. Cynara scolymus – globe artichoke
This vegetable is a star performer at Sophie’s Patch and I never even get around to eating it!? Its striking, large dissected foliage is a brilliant silver and it produces thick upright stems to support the flower buds, which if harvested at the right time can be prepared into mouth-watering taste sensations. It’s on my ‘to do’ list for when I have more time, but for the moment I just enjoy the look of their foliage and seeing the buds open into massive purple thistle-like flowers.
30. Euphorbia rigida – spurge
This spurge has rigid architectural stems to 45cm clothed in blue-grey leaves, and they tend to arch with the weight of lime coloured flower bracts as they age. This variety should be pruned in early autumn to encourage new growth and spring flowers.

33. Nepeta faasennii ‘Walker’s Blue’ – catmint
Catmint is the classic species for underplanting roses and it makes a first-class edging plant in sunny gardens. This is my favourite form which flowers from spring to autumn, longer than other varieties. Its dark lavender-blue flowers are also more striking than other varieties of catmint, and they look great against its silver-green foliage. Growing to 45cm high, when used as a continuous edging, ‘Walker’s Blue’ prevents birds from scratching mulch onto paths. A mid season haircut will tidy up the plants and an annual hard prune to just above ground level is required.
34. Romneya coulteri – Californian tree poppy
This giant perennial to 2m high produces stunning large, white poppy-like flowers above grey-blue foliage in late spring and summer. Although not easy to establish, they are worthwhile persevering with. They need perfect drainage and resent transplanting.

39. Stachys byzantina ‘Big Ears’ – lamb’s ears
Lamb’s ears is a mat forming perennial with soft furry leaves, just like lambs ears, and it make a beautiful silver carpet. The heads of mauve-pink flowers held above the foliage are an added bonus in summer. There are several newer forms of this old-fashioned plant including ‘Big Ears’ which has larger leaves, each up to 20cm long, making a bolder effect, and also a miniature form called S. thirkei, only grows 10cm x 30cm, requiring less ongoing maintenance than the common form.

50. Escholtzia – Californian poppy
I have drifts of this delightful annual with greyish foliage and orange flowers up my driveway and I let it self-seed where it wants in this area. It is also available in other colours however orange seems to naturally work best here.
