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.

Asphodeline lutea is an easy to grow perennial that has great architectural form. The overall impression is distinctly upright, so it is good for adding vertical interest to the garden. In early summer leafy stems arise that bear dense, unbranched cylindrical spikes of gorgeous yellow, star-shaped flowers.

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.

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.

Aquilegia var. stellata 'Barlow Mix' is one of the really exceptional doubles forms of Aquilegia. It is the first Aquilegia series with fully double, spurless flowers. Stylish and elegant, with a graceful upright habit they grow to around 80cm tall. It produces many stems and makes an ideal cut flower.

Native to Canada and the US in all states east of the Rockies, this superb variety is quite unlike the usual Aquilegia. Growing just twelve to eighteen inches tall, with dark-green foliage and eye-catching, scarlet and lemon-yellow flowers which hang like drifts of softly illuminated lanterns.

Aquilegia atrata is a beautiful free flowering species that is native to the alpine meadows and forest clearings of Switzerland and Northern Europe. With many branching stems of deepest coloured, almost black flowers. This is an outstanding, highly sought species that would be a showstopper in any garden.

Composed of a finely balanced selection of annual flowers designed to provide a long succession of flowers from June to September, the Tall Flowers Mix grows 60 to 70cm (24 to 28in) tall and produces large quantities of flowers that are ideal for the border and for the vase.

The Semi-Tall Flowers Mix is a richly flowering mixture of that produces large quantities of 50cm (20in) tall annual flowers for the border or for cutting. As well as being ornamental, they will provide nectar and pollen for bees, butterflies and other insects from early in the year to late in the season.

Incredibly easy to grow the Annual Dwarf Flowers Mix grows to around 30cm (12in) tall. Flowering just 10 to 12 weeks from sowing, these fast-growing plants provide an easy and cost-effective way to give naturalistic planting, plug gaps and fill the border with a summer full of colour.

Japanese Anemones are among the best late summer and autumn border flowers. The flowers open from round, silk-covered buds and in summer rain, look like pearls glistening in the border. Blooming from August to late October, they help push the show into autumn and provide colour when most gardens begin to fade.

Anchusa italica is a wonderfully statuesque plant with vibrant, gentian blue flowers, dense foliage and lance shaped mid green leaves. 'Dropmore' is a 1905 selection that is still available today. They will thrive in a sunny border and make a great companion to rich plums and purple tones.

Hollyhocks are a mysterious and prolific flower with a long and rich history. Traditionally associated with cottage-style borders, the dramatic, near-black flowers of Nigra work equally well in a contemporary, minimalist garden. This unique variety creates an impressive impact against most backgrounds.

This gorgeous award winning Hollyhock has the distinction of being the shortest in the Alcea rosea family. 'Queeny' is a dwarf Hollyhock that reaches only 60cm in height with fully double blooms. Unlike the tall varieties, it is a perennial that can also be used as an annual as it will bloom in its first year.

Alcea rosea ‘Chater's White’ is a dramatic, upright plant, with a spike-like inflorescence that is covered with large buds that open, in a staggered manner, from June to September, from the bottom to the top. Fully double and almost pom-pom in appearance, the fine crepe texture of the petals is so delicate that it allows light to pass through.
