Achillea ‘Cerise Queen’ is a carefree and generously blooming perennial which requires little maintenance to create an explosion of late summer colour. The large, flat-topped clusters of vibrant, pink flowers with tiny white centers are irresistible to butterflies, and also make excellent cut flowers.

Achilleas are traditional border flowers valued for their feathery foliage and striking flat, circular heads of flowers ‘F2 Summer Berries’ is a compact variety growing to only 60cm tall at maturity. This beautiful improved mixture includes the richer tones of red, cerise and pink in addition to many pastel shades.

Achillea millefolium 'Proa' is an improved yarrow, a selected form that is higher yielding, with higher essential oil content, better flower production, and the flowers are more uniformly white. Preferred by those who use yarrow medicinally.

Achillea sibirica var. camtschatica 'Love Parade' is an upright, tufted, perennial yarrow that is native to Siberia. Very different from the common yarrow, with dense clusters of large flat-topped soft pink flowers and glossy, dark green, fern-like leaves, they remain attractive throughout the growing season.

Ajuga genevensis is used throughout the world yet this relatively uncommon form is less well known. This very well behaved, evergreen groundcover has deep gentian blue flower spikes and is by far the showiest of the species. It is often the plant of choice for smaller areas or along edges and pathways.

For most of the year Ajuga is a pleasant, quiet achiever, a very versatile low growing ground cover, with evergreen, rosette-like foliage that hugs the ground like an evergreen carpet but those weeks in spring when the blue flowers appear are simply quite magical.

Alcea ficifolia is reliably perennial and unlike the biennial forms which produce a single spire, they produce many upright stems, resulting in a bushy form. ‘Happy Lights’ is a beautiful strain, a bold blend of white, pink, purple, red, and yellow blooms. If sown early they will bloom in their first year.

Alcea rosea ‘Chater's Rose’ 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.
