Prized for its beautiful silvery foliage, the fine grey-white stems of Artemisia ludoviciana bear silvery-white leaves that are fragrant, fuzzy and soft. This finely textured plant adds a different element to the garden, the texture and leaf form setting them apart from those other garden plants with rather less refined foliage.

Artemisia stelleriana 'Mori's Strain' is a superior, dense, mat-forming selection. Uniquely shaped silver-white felted leaves with deeply divided, rounded lobes, it forms very attractive low mounds, giving an attractive ground-hugging carpet. Its foliage makes a wonderful foil for more colourful flowering plants.

Aubrieta 'Hendersonii' is a vigorous variety that is smothered by rich lilac-purple flowers for several months in spring. It grows to only 10 to 15cm tall at maturity, but with a spread of around 45cm it makes a lively edging to a sunny border, growing over rock walls or placed in stonewalls.

Commonly called ‘Rock Cress’, Aubrieta is a traditional rock garden plant that is lovely spilling out of crevices, growing over rock walls or placed in stonewalls. 'Leichtlinii' forms a low cushion of leaves that is, throughout the summer months, smothered by wonderful deep-carmine flowers.

Aubrieta has long been treasured for its delightful spring show of brightly coloured flowers. ‘Whitewell Gem’ is smothered by large, intense reddish-purple flowers for several months. Lovely spilling out of crevices or over rock walls, the plants can also be used in paving with other ground hugging plants.

‘Indian Prince' has unique petals quite unlike other Calendula, the dark orange rays are in layers of orange, backed with rich mahogany red petals. Easily grown, sown direct in spring or in autumn, they are perfect candidates for cutting and flower arrangements.

Calendula officinalis ‘Ivory Princess’ is a tall show stopper with giant buttery flowers. The petals are a mix of creamy buff-yellow with tips of the serrated, buttercream petals having the tiniest outline of brown, giving a ruffled, lacy effect which beautifully compliments the dark brown eye.

Don’t be misled by the name - Calendula officinalis 'Orange Flash' produces stunning peachy apricot-copper coloured blooms with darker shades of ombré-rose on the reverse. They grow to a height of around 60cm and a spread of 45cm, are an excellent variety for borders and make a stunning cut flower.

'Sunset Buff' is a lovely, more subtle coloured calendula. It is the soft apricot-buff version of 'Indian Prince' with the same crimson petal backs. They grow to a height of around 60cm and a spread of 45cm, are an excellent variety for borders and make a stunning cut flower.

'Snow in Summer' lives up to its name in late spring when the foliage is smothered in luminous white flowers. Beautiful used as a path edging, in a stone wall or cascading over containers. Try it amongst your spring bulbs - tall lily flowering tulips above a dense carpet of white Cerastium… Breathtaking!

Eryngium variifolium ‘Miss Marble’ is a spectacular evergreen perennial. The neat mound of basal leaves are attractively marbled with silver veining.

Long sword-shaped leaves that launch an architectural wonder of tight set thistle-style, white spheres, the flowers of Eryngium yuccifolium are borne on tall branching stems. The unique structure and colour make it highly desirable to gardeners as accent plants in borders and wildflower meadows.

From the Tian Shan Mountains of northern China comes this tough little subshrub that is among the finest expressions of silver foliage to be found. Helichrysum thianshanicum is a superb silver leaved evergreen, subshrub that forms a tight mound of eye-catching silver foliage.

The Kniphofia hybrids have extended both the flower colour and height range. The usual fiery reds and oranges work particularly well in a planting scheme based on 'hot' colours - use them to light up sultry August borders. The cooler yellow, cream, ivory and sometimes green flowers is more restful.

Munstead Lavender is a fragrant robust English lavender that, due to its short size and tightly held blooms, makes a great hedge. It flowers profusely in the spring, after which a good pruning will provide an attractive grey bush with highly aromatic leaves.
